自定义构建配置架构
使用 EAS Build 进行自定义构建的配置选项参考。
为 EAS Build 创建自定义版本有助于自定义项目的构建过程。
🌐 Creating custom builds for EAS Build helps customize the build process for your project.
自定义构建的 YAML 语法
🌐 YAML syntax for custom builds
自定义构建配置文件存储在 .eas/build 目录路径中。它们使用 YAML 语法,并且必须具有 .yml 或 .yaml 文件扩展名。如果你是 YAML 新手或想了解更多语法信息,请参见 在 Y 分钟内学习 YAML。
🌐 Custom build config files are stored inside the .eas/build directory path. They use YAML syntax and must have a .yml or .yaml file extension. If you are new to YAML or want to learn more about the syntax, see Learn YAML in Y minutes.
build
用于描述自定义构建配置的定义。所有用于创建自定义构建的配置选项都在其下指定。
🌐 Defined to describe a custom build configuration. All config options to create a custom build are specified under it.
name
自定义构建的名称,用于在构建日志中识别它。EAS 构建使用此属性在仪表板中显示构建名称。
🌐 The name of your custom build that is used to identify it in the build logs. EAS Build uses this property to display the name of your build in the dashboard.
例如,构建名称是 Run tests:
🌐 For example, the build name is Run tests:
build: name: Run tests steps: - eas/checkout - run: name: Install dependencies command: npm install
steps
步骤用于描述一系列操作,可以是命令或函数调用的形式。当自定义构建在 EAS Build 上运行时,这些操作将会执行。你可以在构建配置中定义单个或多个步骤。然而,每次构建必须至少定义一个步骤。
🌐 Steps are used to describe a list of actions, either in the form of commands or function calls. These actions are executed when a custom build runs on EAS Build. You can define single or multiple steps in a build config. However, it is required to define at least one step per build.
每个步骤都配置有以下属性:
🌐 Each step is configured with the following properties:
steps[].run
run 键用于触发一组指令。例如,run 键用于通过 npm install 命令安装依赖:
🌐 The run key is used to trigger a set of instructions. For example, a run key is used to install dependencies using the npm install command:
build: name: Install npm dependencies steps: - eas/checkout - run: name: Install dependencies command: npm install
你也可以使用 steps[].run 来执行单行或多行的 Shell 命令:
🌐 You can also use steps[].run to execute single or multiline shell commands:
build: name: Run inline shell commands steps: - run: echo "Hello world" - run: | echo "Multiline" echo "bash commands"
使用单步
🌐 Use a single step
例如,带有以下 steps 的构建配置将打印 "Hello world":
🌐 For example, a build config with the following steps will print "Hello world":
build: name: Greeting steps: - run: echo "Hello world"
注意: 在
run之前的-被视为缩进。
使用多个步骤
🌐 Use multiple steps
当定义多个 steps 时,它们会按顺序执行。例如,具有以下 steps 的构建配置将首先签出项目,安装 npm 依赖,然后运行命令以执行测试:
🌐 When multiple steps are defined, they are executed sequentially. For example, a build config with the following steps will first check out the project, install npm dependencies, and then run a command to run tests:
build: name: Run tests steps: - eas/checkout - run: name: Install dependencies command: npm install - run: name: Run tests command: | echo "Running tests..." npm test
与其他步骤共享环境变量
🌐 Sharing environment variables with other steps
在一个步骤的 command 中导出的环境变量(使用 export)不会自动暴露给其他步骤。要将环境变量共享给其他步骤,请使用 set-env 可执行文件。
🌐 Environment variables exported (using export) in one step's command are not automatically exposed to other steps. To share an environment variable with other steps, use the set-env executable.
set-env 期望被调用时传入两个参数:环境变量的名称和数值。例如,set-env NPM_TOKEN "abcdef" 将会将 $NPM_TOKEN 变量及其值 abcdef 暴露给其他步骤。
注意: 与
set-env共享的变量不会自动在本地导出。你需要自己调用export。
build: name: Shared environment variable example steps: - run: name: Set environment variables command: | set -x # Set variable ENV_TEST_LOCAL="present-only-in-current-shell-context" # Set and export variable export ENV_TEST_LOCAL_EXPORT="present-in-current-step" # Set shared variable set-env ENV_TEST_SET_ENV "present-in-following-steps" # Will print "ENV_TEST_LOCAL: present-only-in-current-shell-context" # because current shell has access to this local variable. echo "ENV_TEST_LOCAL: $ENV_TEST_LOCAL" # Will print "ENV_TEST_LOCAL_EXPORT: present-in-current-step" # because export also sets the local variable value. echo "ENV_TEST_LOCAL_EXPORT: $ENV_TEST_LOCAL_EXPORT" # Will "ENV_TEST_SET_ENV: " # because set-env does not set or export variables. echo "ENV_TEST_SET_ENV: $ENV_TEST_SET_ENV" # Will only print LOCALLY_EXPORTED_ENV, # because it is the only export-ed variable. env | grep ENV_TEST_ - run: name: Check variables values in next step command: | set -x # Will print "ENV_TEST_LOCAL: ", because ENV_TEST_LOCAL # is only a local variable in previous step. echo "ENV_TEST_LOCAL: $ENV_TEST_LOCAL" # Will print "ENV_TEST_LOCAL_EXPORT: " # because export does not share a variable to other steps. echo "ENV_TEST_LOCAL_EXPORT: $ENV_TEST_LOCAL_EXPORT" # Will print "ENV_TEST_SET_ENV: present-in-following-steps" # because set-env "exported" variable to other steps. echo "ENV_TEST_SET_ENV: $ENV_TEST_SET_ENV" # Will only print ENV_TEST_SET_ENV, # because set-env "exported" it to other steps. env | grep ENV_TEST_
steps[].run.name
构建日志中用于显示步骤名称的名称。
🌐 The name used in build logs to display the name of the step.
steps[].run.command
command 定义了在执行步骤时运行的自定义 Shell 命令。每个步骤必须定义一个命令。它可以是多行的 Shell 命令:
🌐 The command defines a custom shell command to run when a step is executed. It is required to define a command for each step. It can be a multiline shell command:
build: name: Run tests steps: - eas/checkout - run: name: Run tests command: | echo "Running tests..." npm test
steps[].run.working_directory
working_directory 用于从项目的根目录定义一个已存在的目录。在步骤中定义了一个已存在的路径后,使用它会更改该步骤的当前目录。例如,可以创建一个步骤来列出 assets 目录中的所有资源,该目录位于你的 Expo 项目中。working_directory 设置为 assets:
🌐 The working_directory is used to define an existing directory from the project's root directory. After an existing path is defined in a step, using it changes the current directory for that step. For example, a step is created to list all the assets inside the assets directory, which is a directory in your Expo project. The working_directory is set to assets:
build: name: Demo steps: - eas/checkout - run: name: List assets working_directory: assets command: ls -la
steps[].run.shell
用于定义步骤的默认可执行 shell。例如,将步骤的 shell 设置为 /bin/sh:
🌐 Used to define the default executable shell for a step. For example, the step's shell is set to /bin/sh:
build: name: Demo steps: - run: shell: /bin/sh command: | echo "Steps can use another shell" ps -p $$
steps[].run.inputs
输入值会提供给一个步骤。例如,你可以使用 input 来提供一个值:
🌐 Input values are provided to a step. For example, you can use input to provide a value:
build: name: Demo steps: - run: name: Say Hi inputs: name: Expo command: echo "Hi, ${ inputs.name }!"
steps[].run.outputs
在某个步骤中预期会有输出值。例如,一个步骤的输出值为 Hello world:
🌐 An output value is expected during a step. For example, a step has an output value of Hello world:
build: name: Demo steps: - run: name: Produce output outputs: [value] command: | echo "Producing output for another step" set-output value "Output from another step..."
steps[].run.outputs.required
输出值可以使用布尔值来表示该输出值是否是必需的。例如,一个函数可以没有必需的输出值:
🌐 An output value can use a boolean to indicate if the output value is required or not. For example, a function does not have a required output value:
build: name: Demo steps: - run: name: Produce another output id: id456 outputs: - required_param - name: optional_param required: false command: | echo "Producing more output" set-output required_param "abc 123 456"
steps[].run.id
为一个步骤定义 id 可以:
🌐 Defining an id for a step allows:
- 多次调用产生一个或多个输出的同一函数
- 使用从一个步骤到另一步骤的输出
调用同一个函数一次或多次
🌐 Call the same function one or more times
例如,以下函数生成一个随机数:
🌐 For example, the following function generates a random number:
functions: random: name: Generate random number outputs: [value] command: set-output value `random_number`
在构建配置中,我们使用 random 函数生成两个随机数并打印它们:
🌐 In a build config, let's use the random function to generate two random numbers and print them:
build: name: Functions Demo steps: - random: id: random_1 - random: id: random_2 - run: name: Print random numbers inputs: random_1: ${ steps.random_1.value } random_2: ${ steps.random_2.value } command: | echo "${ inputs.random_1 }" echo "${ inputs.random_2 }"
使用从一个步骤到另一步骤的输出
🌐 Use output from one step to another
例如,以下构建配置演示了如何使用从一个步骤到另一个步骤的输出:
🌐 For example, the following build config demonstrates how to use output from one step to another:
build: name: Outputs demo steps: - run: name: Produce output id: id123 # <---- !!! outputs: [foo] command: | echo "Producing output for another step" set-output foo bar - run: name: Use output from another step inputs: foo: ${ steps.id123.foo } command: | echo "foo = \"${ inputs.foo }\""
functions
用于描述可在构建配置中使用的可重用函数。创建函数的所有配置选项通过以下属性指定:
🌐 Defined to describe a reusable function that can be used in a build config. All config options to create a function are specified with the following properties:
functions.[function_name]
[function_name] 是你定义的用于在 build.steps 中识别它的函数名称。例如,你可以定义一个名为 greetings 的函数:
🌐 The [function_name] is the name of a function that you define to identify it in the build.steps. For example, you can define a function with the name greetings:
functions: greetings: name: Say Hi!
functions.[function_name].name
在构建日志中用于显示函数名称的名称。例如,具有显示名称 Say Hi! 的函数:
🌐 The name that is used in build logs to display the name of the function. For example, a function with the display name Say Hi!:
functions: greetings: name: Say Hi!
functions.[function_name].inputs
输入值被提供给函数。
🌐 Input values are provided to a function.
inputs[].name
输入值的名称。它用作访问输入值的标识符,例如在 bash 命令插值中使用。
🌐 The name of the input value. It is used as an identifier to access the input value such as in bash command interpolation.
functions: greetings: name: Say Hi! inputs: - name: name default_value: Hello world command: echo "${ inputs.name }!"
inputs[].required
布尔值,用于指示输入值是否为必填。例如,一个函数可能没有必填值:
🌐 Boolean to indicate if the input value is required or not. For example, a function does not have a required value:
functions: greetings: name: Say Hi! inputs: - name: name required: false
inputs[].type
输入值的类型。它可以是 string、num 或 json。
🌐 The type of the input value. It can be either string, num or json.
函数调用中设置的输入值以及函数的 default_value 和 allowed_values 都会根据类型进行验证。
🌐 Input values set in the function call as well as default_value and allowed_values for the function are validated against the type.
默认输入 type 是 string。
🌐 The default input type is string.
例如,一个函数有一个类型为 string 的输入值:
🌐 For example, a function has an input value of type string:
functions: greetings: name: Say Hi! inputs: - name: name type: string - name: age type: num - name: other_data type: json
inputs[].default_value
你可以使用 default_value 提供一个默认输入。例如,一个函数的默认值为 Hello world:
🌐 You can use default_value to provide one default input. For example, a function has a default value of Hello world:
functions: greetings: name: Say Hi! inputs: - name: name default_value: Hello world
inputs[].allowed_values
你可以使用 allowed_values 来在数组中提供多个值。例如,某个函数有多个允许的值:
🌐 You can use allowed_values to provide multiple values in an array. For example, a function has multiple allowed values:
functions: greetings: name: Say Hi! inputs: - name: name default_value: Hello world allowed_values: [Hi, Hello, Hey] type: string
多个输入值
🌐 Multiple input values
可以向函数提供多个输入值。
🌐 Multiple input values can be provided to a function.
functions: greetings: name: Say Hi! inputs: - name: name default_value: Expo - name: greeting default_value: Hi allowed_values: [Hi, Hello] command: echo "${ inputs.greeting }, ${ inputs.name }!"
functions.[function_name].outputs
函数期望有一个输出值。例如,一个函数的输出值为 Hello world:
🌐 An output value is expected from a function. For example, a function has an output value of Hello world:
functions: greetings: name: Say Hi! outputs: [value] command: set-output value "Hello world"
outputs[].name
输出值的名称。它用作标识符,以便在另一步中访问该输出值:
🌐 The name of the output value. It is used as an identifier to access the output value in another step:
functions: greetings: name: Say Hi! outputs: - name: name
outputs[].required
布尔值,用于指示输出值是否为必需。例如,一个函数可能没有必需的输出值:
🌐 Boolean to indicate if the output value is required or not. For example, a function does not have a required output value:
functions: greetings: name: Say Hi! outputs: - name: value required: false
functions.[function_name].command
用于定义在执行函数时要运行的命令,如果你希望该函数是一个简单的 shell 脚本。每个函数必须定义一个 command 或 path 指向实现该函数的 JS/TS 模块。例如,命令 echo "Hello world" 用于打印一条消息:
🌐 Used to define the command to run when a function is executed, if you wish the function to be a simple shell script. Each function is required to define either a command or a path to JS/TS module implementing the function. For example, the command echo "Hello world" is used to print a message:
functions: greetings: name: Say Hi! command: echo "Hi!"
functions.[function_name].path
用于定义实现该函数的 JavaScript/TypeScript 模块的路径。每个函数必须定义 command 或 path 属性。例如,路径 ./greetings 用于执行在 greetings 模块中声明的 greetings 函数:
🌐 Used to define the path to a JavaScript/TypeScript module implementing the function. Each function is required to define either a command or a path property. For example, the path ./greetings is used to execute a greetings function declared in the greetings module:
functions: greetings: name: Say Hi! path: ./greetings
functions.[function_name].shell
用于定义执行函数步骤的默认可执行 shell。例如,步骤的 shell 设置为 /bin/sh:
🌐 Used to define the default executable shell for a step where a function is executed. For example, the step's shell is set to /bin/sh:
functions: greetings: name: Say Hi! shell: /bin/sh command: echo "Hi!"
functions.[function_name].supported_platforms
用于定义函数支持的平台。默认支持所有平台。允许的平台有:darwin、linux。
🌐 Used to define the supported platforms for a function. Defaults to all platforms. Allowed platforms: darwin, linux.
例如,该函数支持的平台是 darwin(macOS):
🌐 For example, the function's supported platform is darwin (macOS):
functions: greetings: name: Say Hi! supported_platforms: [darwin] command: echo "Hi!"
import
用于从其他配置文件导入函数的配置文件路径列表。导入的文件不能包含 build 部分。
🌐 A config file path list used to import functions from other config files. Imported files cannot have the build section.
例如,下面的构建配置导入了两个文件并调用了两个导入的函数——say_hi 和 say_bye。
🌐 For example, the following build config imports two files and calls two imported functions - say_hi and say_bye.
函数
🌐 Functions
内置 EAS 功能
🌐 Built-in EAS functions
EAS 提供了一组内置可重用函数,你可以在构建配置中使用这些函数,而无需定义函数定义。
🌐 EAS provides a set of built-in reusable functions that you can use in a build config without defining the function definition.
信息 提示: 任何由 EAS 提供的内置函数都必须以
eas/前缀开头。
eas/build
封装整个 EAS Build 构建过程的一体化功能。它会根据你在 eas.json 中的构建配置文件设置确定最佳构建配置。
🌐 The all-in-one function that encapsulates the entire EAS Build build process. It resolves the best build configuration based on your build profile's settings from eas.json.
它非常适合那些希望完成构建而不必担心手动更改和配置构建过程的人。如果你有兴趣在构建过程之前或之后使用其他自定义步骤,并且不想更改构建过程本身,它也可以成为你自定义构建配置的一个很好的起点。
🌐 It's ideal for people who want to have the build done without worrying about altering and configuring the build process manually. It can be a great starting point for your custom build configuration if you are interested in using other custom steps before or after the build process and you don't want to change the build process itself.
为了更好地控制构建过程并根据你的需求进行自定义,请参阅以下由 eas/build 在后台运行的自定义函数和步骤。它们会根据你的构建配置文件的设置作为构建过程执行。
🌐 To have more control over the build process and customize it as per your requirements, see the following custom functions and steps that run in the background by eas/build. They are executed as a build process based on your build profile's configuration.

eas/maestro_test
安装 Maestro、准备测试环境(Android 模拟器或 iOS 模拟器)并测试应用的一体化功能。
🌐 All-in-one function that installs Maestro, prepares a testing environment (Android Emulator or iOS Simulator), and tests the app.
在幕后,它使用:
🌐 Behind the scenes, it uses:
eas/install_maestro安装 Maestroeas/start_android_emulator在需要时启动 Android 模拟器eas/start_ios_simulator在需要时启动 iOS 模拟器- 自定义
run将 .apk 安装到正在运行的 Android 模拟器,将 .app 安装到 iOS 模拟器 - 一系列
run用于对提供的每个流程执行maestro test eas/upload_artifact上传 Maestro 测试工件作为构建工件
警告 我们注意到,如果在 Xcode 15.0 或 15.2 的镜像上运行,Maestro 测试经常会超时。请使用
latest镜像以避免任何问题。
如果你需要自定义 Maestro 版本、运行特定的 Android 模拟器或 iOS 模拟器,或上传多个构建工件,你将需要自己编写这一系列步骤。
🌐 If you need to customize the Maestro version, run a specific Android Emulator or iOS Simulator, or upload multiple build artifacts you will need to write this series of steps yourself.
在 GitHub 上查看 eas/maestro_test 函数的源代码。
eas/checkout
签出你的项目源文件。
🌐 Checks out your project source files.
对于使用基于 Git 的项目源的构建,该步骤默认使用构建记录的提交。使用 ref 可以签出不同的分支、标签或提交:
🌐 For builds with Git-based project sources, the step uses the build's recorded commit by default. Use ref to check out a different branch, tag, or commit:
ref 接受:
- 一个分支,可以是像
feature/add-icon这样的裸名称,也可以是像refs/heads/feature/add-icon这样的限定引用。仓库最终会在该分支上。 - 一个标签,作为像
refs/tags/v1.2.3这样的限定引用。仓库最终处于分离的HEAD上。 - 一个完整的提交 SHA。仓库最终会处于分离的
HEAD状态。
ref 输入仅在你的项目源来自 Git 仓库时有效,例如通过 GitHub 集成触发的构建。本地构建和上传的项目压缩包不支持它。将此步骤放在 eas/build 之前,后者会在内部检出项目。
🌐 The ref input only works when your project sources come from a Git repository, for example, a build triggered through the GitHub integration. Local builds and uploaded project tarballs do not support it. Place the step before eas/build, which checks out the project internally.

🌐 Runs fastlane gym command against the Gymfile located in the ios project directory to build the iOS app.
在 GitHub 上查看 eas/run_fastlane 函数的源代码。
eas/find_and_upload_build_artifacts
警告 当前每个构建任务中,每种工件类型只能上传一次。
如果你在配置了buildArtifactPaths的构建配置文件中使用eas/find_and_upload_build_artifacts,并且该步骤发现并上传了一些构建工件,那么之后的任何eas/upload_artifact步骤都会失败。
为了解决这个问题,目前我们建议从自定义构建的配置文件中删除buildArtifactPaths,如果需要在 YAML 中调用,可使用eas/upload_artifact手动上传工件。
自动从默认位置使用 buildArtifactPaths 配置查找并上传应用归档、额外的构建产物和 Xcode 日志。将找到的产物上传到 EAS 服务器。
🌐 Automatically finds and uploads application archive, additional build artifacts, and Xcode logs from the default locations and using the buildArtifactPaths configuration. Uploads found artifacts to the EAS servers.
在 GitHub 上查看 eas/find_and_upload_build_artifacts 函数的源代码。
eas/upload_embedded_bundle
上传构建生成的应用中的嵌入打包包。EAS 更新然后可以将你稍后发布到同一通道的更新作为补丁来提供。
🌐 Uploads the embedded bundle from the app that the build produced. EAS Update can then serve updates that you publish later to the same channel as patches against it.
eas/build 会在启用上传时为你运行这一步。当你的配置使用单独的步骤构建应用而不是 eas/build 时,你需要自己添加它。把它放在构建应用那一步之后运行,比如 eas/run_gradle 或 eas/run_fastlane。
与 eas/build 不同,这一步不会检查 SDK 版本或 EAS_UPDATE_UPLOAD_EMBEDDED_BUNDLE 和 EAS_UPDATE_EXPERIMENTAL_UPLOAD_EMBEDDED_BUNDLE 环境变量。在这些情况下,它会跳过上传:
🌐 Unlike eas/build, the step does not check the SDK version or the EAS_UPDATE_UPLOAD_EMBEDDED_BUNDLE and EAS_UPDATE_EXPERIMENTAL_UPLOAD_EMBEDDED_BUNDLE environment variables. It skips the upload in these cases:
- 你的项目中没有配置 EAS 更新。
- 这个版本是开发版本。
- 这个构建是一个 iOS 模拟器构建。
这一步会在你的构建配置文件中 applicationArchivePath 设置的位置找到应用。如果没有这个属性,这一步会在默认的构建输出目录中查找。然后,这一步会把 bundle 上传到同一配置文件中的 channel 设置,而不是上传到 eas/configure_eas_update 的 channel 输入。
🌐 The step finds the app at the applicationArchivePath set in your build profile. Without that property, the step looks in the default build output directory. The step uploads the bundle to the channel set in the same profile, not to the channel input of eas/configure_eas_update.
当上传失败时,这一步会导致构建失败。例如,当构建配置文件没有 channel 或者这一步找不到应用时,它就会失败。当 eas/build 运行这一步时,上传失败只会记录一个警告。要在你自己的配置中记录失败并继续构建,请将 ignore_error 设置为 true:
🌐 The step fails the build when the upload fails. For example, it fails when the build profile has no channel or when the step cannot find the app. When eas/build runs the step, an upload failure only logs a warning. To log the failure and continue the build in your own config, set ignore_error to true:
警告 在上传功能启用的
eas/build配置中不要添加这一步。eas/build已经会上传包。再次上传同一个包会导致这一步失败。
在 GitHub 上查看 eas/upload_embedded_bundle 函数的源代码。
eas/upload_artifact
将作业工作区中的文件作为附件上传到运行的工件中。上传的工件会出现在运行的 Artifacts 部分,并可以在后续作业中通过 eas/download_artifact 检索。
🌐 Uploads files from the job's workspace as an artifact attached to the run. Uploaded artifacts appear in the run's Artifacts section and can be retrieved in a later job with eas/download_artifact.
警告 当前每个构建任务中,每种工件类型只能上传一次。
如果你在配置了buildArtifactPaths的构建配置文件中使用eas/find_and_upload_build_artifacts,并且该步骤发现并上传了一些构建工件,那么之后的任何eas/upload_artifact步骤都会失败。
为了解决这个问题,目前我们建议从自定义构建的配置文件中删除buildArtifactPaths,如果需要在 YAML 中调用,可使用eas/upload_artifact手动上传工件。

🌐 Starts an iOS Simulator you can use to test your apps on. Only available when running a build for iOS.
在 GitHub 上查看 eas/start_ios_simulator 函数的源代码。
eas/send_slack_message
向配置的 Slack webhook URL 发送指定消息,然后它会将消息发布到相关的 Slack 通道。消息可以以纯文本形式指定,也可以以 Slack Block Kit 消息形式指定。
🌐 Sends a specified message to a configured Slack webhook URL, which then posts it in the related Slack channel. The message can be specified as plaintext or as a Slack Block Kit message.
你可以在消息中引用构建作业属性并使用其他步骤的输出进行动态评估。例如,'Build URL: ${ eas.job.expoBuildUrl }'、Build finished with status: ${ steps.run_fastlane.status_text }、Build failed with error: ${ steps.run_gradle.error_text }。
🌐 You can reference build job properties and use other steps outputs in the message for dynamic evaluation.
For example, 'Build URL: ${ eas.job.expoBuildUrl }', Build finished with status: ${ steps.run_fastlane.status_text }, Build failed with error: ${ steps.run_gradle.error_text }.
在 GitHub 上查看 eas/send_slack_message 函数的源代码。
以下函数可将你的构建连接到 PostHog。运行 eas integrations:posthog:connect 来关联一个 PostHog 项目并设置这些函数读取的环境变量。eas/posthog_capture_event 使用你的公共项目 API 密钥,而其他函数使用带有各自权限范围的 PostHog 个人 API 密钥。有关设置,请参阅 使用 PostHog,有关完整工作流程,请参阅 EAS 工作流程的 PostHog 使用示例。
🌐 The following functions connect your build to PostHog. Run eas integrations:posthog:connect to link a PostHog project and set the environment variables these functions read. eas/posthog_capture_event uses your public project API key, while the other functions use a PostHog personal API key with the scopes noted for each one. For setup, see Using PostHog, and for complete workflows, see PostHog recipes for EAS Workflows.
eas/posthog_capture_event
向 PostHog 发送一个分析事件。用它来标记你的构建、发布以及 PostHog 时间线上的其他重要节点。
🌐 Sends an analytics event to PostHog. Use it to mark builds, releases, and other milestones on your PostHog timeline.
当你不提供 distinct_id 时,事件会以匿名方式发送,并且不会创建 PostHog 的 用户档案。
🌐 When you do not provide a distinct_id, the event is sent anonymously and does not create a PostHog person profile.
在 GitHub 上查看 eas/posthog_capture_event 函数的源代码。
eas/posthog_flag_rollout
启用、禁用或推出一个 PostHog 功能标志。该函数通过键查找标志,然后更新它。至少提供 active、rollout_percentage 或 payload 中的一个。
🌐 Enables, disables, or rolls out a PostHog feature flag. The function looks up the flag by key and then updates it. Provide at least one of active, rollout_percentage, or payload.
在 GitHub 上查看 eas/posthog_flag_rollout 函数的源代码。
eas/posthog_wait_for_metric
暂停直到 HogQL 查询返回一个满足比较的数字。可以用它来根据某个指标做判断,比如等到最近几分钟的错误数量保持较低。这个函数每隔 interval_seconds 运行一次查询,直到比较为真或 timeout_seconds 时间过去。
🌐 Pauses until a HogQL query returns a number that satisfies a comparison. Use it to gate on a metric, such as holding until the error count over the last few minutes stays low. The function runs the query every interval_seconds until the comparison is true or timeout_seconds elapses.
信息 这一步没有
ignore_error输入。超时或无法读取的查询总会导致步骤失败。
输出
🌐 Outputs
在 GitHub 上查看 eas/posthog_wait_for_metric 函数的源代码。
eas/posthog_wait_for_query
暂停,直到 HogQL 查询返回 true。当条件在查询中更容易表达时使用。对于带有明确阈值的数值比较,请改用 eas/posthog_wait_for_metric。当第一行第一列为 true 或非零数字时,该步骤会清除。
🌐 Pauses until a HogQL query returns true. Use it when the condition is easier to express in the query itself. For a numeric comparison with an explicit threshold, use eas/posthog_wait_for_metric instead. The step clears when the first column of the first row is true or a nonzero number.
信息 像
eas/posthog_wait_for_metric一样,这一步没有ignore_error输入。超时或无法读取的查询总会导致这一步失败。
在 GitHub 上查看 eas/posthog_wait_for_query 函数的源代码。
eas/posthog_annotation
在项目时间线上创建一个 PostHog 注释。注释会显示在你的 PostHog 图表上,这样它们就可以用来在受影响的指标旁标记构建、发布和其他里程碑。
🌐 Creates a PostHog annotation on the project timeline. Annotations show up on your PostHog charts, which makes them useful for marking builds, releases, and other milestones next to the metrics they affect.
在 GitHub 上查看 eas/posthog_annotation 函数的源代码。
eas/posthog_upload_sourcemaps
将 JavaScript 源映射上传到 PostHog,以便 PostHog 在错误跟踪中符号化堆栈跟踪。在生成 bundle 的步骤之后,在同一个任务中运行它,这样 bundle 和源映射就会保存在磁盘上。使用 npx expo export --source-maps 导出,并根据源映射指南配置 PostHog 的 Metro 配置,这样 bundle 就会包含与其源映射匹配的 chunk ID。
🌐 Uploads JavaScript source maps to PostHog so that PostHog symbolicates stack traces in error tracking. Run it after the step that produces your bundle, in the same job, so the bundle and source maps are available on disk. Export with npx expo export --source-maps, and configure the PostHog Metro config from the Source maps guide so bundles carry the chunk IDs that match them to their source maps.
警告 这一步会运行 PostHog CLI,它无法区分权限错误和其他任何失败。与其他 PostHog 功能不同,设置
ignore_error: true也会隐藏认证和权限范围错误。
在 GitHub 上查看 eas/posthog_upload_sourcemaps 函数的源代码。
使用内置的 EAS 功能构建应用
🌐 Using built-in EAS functions to build an app
使用内置的 EAS 功能,你可以为不同的构建类型重新创建默认的 EAS 构建过程。
🌐 Using the built-in EAS functions you can recreate the default EAS Build process for different build types.
例如,要触发一个为 Android 创建内部分发构建并为 iOS 创建模拟器构建的构建,你可以使用以下配置:
🌐 For example, to trigger a build that creates internal distribution build for Android and a simulator build for iOS you can use the following configuration:
要为 Android 创建 Google Play 商店版本并为 iOS 创建 Apple App Store 版本,你可以使用以下配置:
🌐 To create a Google Play Store build for Android and an Apple App Store build for iOS you can use the following configuration:
查看 示例仓库 以获取更详细的示例:
🌐 Check out the example repository for more detailed examples:
一个自定义 EAS 构建示例,其中包含自定义构建的示例,如设置函数、使用环境变量、上传工件等。
在 build 中使用可重用函数
🌐 Use a reusable function in a build
例如,一个自定义构建配置包含以下可重用函数,其中包含一个用于打印回显消息的命令。
🌐 For example, a custom build config with the following reusable function contains a single command to print a message that is echoed.
functions: greetings: - name: name default_value: Hello world inputs: [value] command: echo "${ inputs.name }, { inputs.value }"
上述函数可以在 build 中如下使用:
🌐 The above function can be used in a build as follows:
build: name: Functions Demo steps: - greetings: inputs: value: Expo
信息 提示:
build.steps可以依次执行多个可重用的functions。
在 build 中覆盖值
🌐 Override values in a build
你可以覆盖以下属性的值:
🌐 You can override values for the following properties:
working_directorynameshell
例如,一个名为 list_files 的可重用函数:
🌐 For example, a reusable function called list_files:
functions: list_files: name: List files command: ls -la
当在构建配置中调用 list_files 时,它会列出项目根目录中的所有文件:
🌐 When list_files is called in a build config, it lists all files in the root directory of a project:
build: name: List files steps: - eas/checkout - list_files
你可以使用 working_directory 属性来覆盖函数调用的行为,通过指定目录的路径来列出不同目录中的文件:
🌐 You can use the working_directory property to override the behavior in the function call to list the files in a different directory by specifying the path to that directory:
build: name: List files steps: - eas/checkout - list_files: working_directory: /a/b/c
