serverless-plugin-typescript

serverless

无服务器插件零配置 Typescript 支持

3boysdad Update

原始 NPM 模块:http:

//www.npmjs.com/package/serverless-plugin-typescript此版本的 serverless-typescript-plugin 修复了 Windows 操作系统的符号链接问题,导致以下错误:

1) EPERM:不允许操作,符号链接…

当尝试创建符号链接到构建目录中的“package.json”文件时。

我不会为原始插件创建 PR,因为它现在似乎已经死了。 虽然我的解决方案有效,但我很确定这只是一个 hack。

Features

  • Zero-config: Works out of the box without the need to install any other compiler or plugins
  • Supports ES2015 syntax + features (export, import, async, await, Promise, …)
  • Supports sls package, sls deploy and sls deploy function
  • Supports sls invoke local + --watch mode
  • Integrates nicely with serverless-offline

Install

yarn add --dev @3boysdad/serverless-plugin-typescript

npm install --save-dev @3boysdad/serverless-plugin-typescript

添加以下插件到你的serverless.yml

plugins:
  - '@3boysdad/serverless-plugin-typescript'

Configure

example 文件夹 一个最小的例子。

tsconfig.json

插件使用的默认 tsconfig.json 文件如下所示:

{
  "compilerOptions": {
    "preserveConstEnums": true,
    "strictNullChecks": true,
    "sourceMap": true,
    "target": "es5",
    "outDir": ".build",
    "moduleResolution": "node",
    "lib": ["es2015"],
    "rootDir": "./"
  }
}

注意 1:不能覆盖 outDirrootDir 选项。 ** 考虑“修复”这个 ** 因为它看起来很老套。

注意 2:不要将此存储库中的 tsconfig.json 与上面提到的混淆。

Including extra files

个人而不是这个请使用并安装插件 - serverless-plugin-include-dependencies。

Usage

Google Cloud Functions

通过 serverless-google-cloudfunctions 使用 Google Cloud Functions 时 插件,您只需在 package.json 中提供一个 main 字段:

{
  // ...
  "main": "handler.js",
  // ..
}

此插件将自动正确编译您的打字稿。 笔记 该字段必须引用编译后的文件名,即以 .js 结尾 扩大。

如果未找到 main 字段,则此插件将使用 index.js。 前 编译开始,它将检查指示的文件是否存在 .ts 扩展名,然后再实际尝试编译它。

Automatic compilation

正常的 Serverless 部署过程将自动使用 Typescript 进行编译:

  • Create the Serverless project with serverless create -t aws-nodejs
  • Install Serverless Typescript as above
  • Deploy with serverless deploy

Usage with serverless-offline

该插件与 serverless-offline 集成得很好 在本地模拟 AWS Lambda 和 AWS API Gateway。

将插件添加到您的 serverless.yml 文件并确保 @hewmen/serverless-plugin-typescriptserverless-offline 之前,因为顺序很重要:

  plugins:
    ...
    - '@hewmen/serverless-plugin-typescript'
    ...
    - serverless-offline
    ...

运行 serverless offlineserverless offline start 以启动 Lambda/API 模拟。

serverless offline 相比,start 命令将触发一个 init 和一个 end 生命周期钩子,这是需要的serverless-offline 和例如 serverless-dynamodb-local 关闭资源(见下文)

serverless-dynamodb-local

配置您的服务与上述相同,但另外添加 serverless- dynamodb-local 插件如下:

  plugins:
    - '@hewmen/serverless-plugin-typescript'
    - serverless-dynamodb-local
    - serverless-offline

运行serverless offline start

Other useful options

您可以使用 --dontPrintOutput 和 使用 --noTimeout 禁用超时。

Run a function locally

要在本地运行已编译的函数,您可以:

$ serverless invoke local --function <function-name>

选项是:

  • --function or -f (required) is the name of the function to run
  • --watch - recompile and run a function locally on source changes
  • --path or -p (optional) path to JSON or YAML file holding input data
  • --data or -d (optional) input data

Enabling source-maps

您可以通过安装和使用以下插件轻松启用对源映射的支持(使堆栈跟踪更易于阅读):

yarn add --dev source-map-support
// inside of your function
import 'source-map-support/register'

如果您正在使用 webpack(最有可能)。 添加 devtool: 'source-map'webpack.config.js

module.exports = {
  .... snip ....
  devtool: 'source-map',
  .... snip ....

}

serverless

Serverless plugin for zero-config Typescript support

3boysdad Update

Original NPM Module: http://www.npmjs.com/package/serverless-plugin-typescript

This version of serverless-typescript-plugin fixes symbolic link issue with Windows OS resulting in the following errors:

1) EPERM: operation not permitted, symlink…

When trying to create symlink to the "package.json" file in the build directory.

I won't create a PR for the original plugin as it seems dead now. And while my solution works, I am pretty sure it's only a hack.

Features

  • Zero-config: Works out of the box without the need to install any other compiler or plugins
  • Supports ES2015 syntax + features (export, import, async, await, Promise, …)
  • Supports sls package, sls deploy and sls deploy function
  • Supports sls invoke local + --watch mode
  • Integrates nicely with serverless-offline

Install

yarn add --dev @3boysdad/serverless-plugin-typescript

or

npm install --save-dev @3boysdad/serverless-plugin-typescript

Add the following plugin to your serverless.yml:

plugins:
  - '@3boysdad/serverless-plugin-typescript'

Configure

See example folder for a minimal example.

tsconfig.json

The default tsconfig.json file used by the plugin looks like this:

{
  "compilerOptions": {
    "preserveConstEnums": true,
    "strictNullChecks": true,
    "sourceMap": true,
    "target": "es5",
    "outDir": ".build",
    "moduleResolution": "node",
    "lib": ["es2015"],
    "rootDir": "./"
  }
}

Note 1: The outDir and rootDir options cannot be overwritten. ** mulling over 'fixing' this ** as it seems rather hacky.

Note 2: Don't confuse the tsconfig.json in this repository with the one mentioned above.

Including extra files

Personally rather than this please use and install the plugin - serverless-plugin-include-dependencies.

Usage

Google Cloud Functions

When using with Google Cloud Functions via the serverless-google-cloudfunctions plugin, you simply have to provide a main field in your package.json:

{
  // ...
  "main": "handler.js",
  // ..
}

And this plugin will automatically compile your typescript correctly. Note that the field must refer to the compiled file name, namely, ending with a .js extension.

If a main field was not found, then this plugin will use index.js. Before compilation begins, it will check to see that the file indicated exists with a .ts extension before actually trying to compile it.

Automatic compilation

The normal Serverless deploy procedure will automatically compile with Typescript:

  • Create the Serverless project with serverless create -t aws-nodejs
  • Install Serverless Typescript as above
  • Deploy with serverless deploy

Usage with serverless-offline

The plugin integrates very well with serverless-offline to simulate AWS Lambda and AWS API Gateway locally.

Add the plugins to your serverless.yml file and make sure that @hewmen/serverless-plugin-typescript precedes serverless-offline as the order is important:

  plugins:
    ...
    - '@hewmen/serverless-plugin-typescript'
    ...
    - serverless-offline
    ...

Run serverless offline or serverless offline start to start the Lambda/API simulation.

In comparison to serverless offline, the start command will fire an init and a end lifecycle hook which is needed for serverless-offline and e.g. serverless-dynamodb-local to switch off resources (see below)

serverless-dynamodb-local

Configure your service the same as mentioned above, but additionally add the serverless-dynamodb-local plugin as follows:

  plugins:
    - '@hewmen/serverless-plugin-typescript'
    - serverless-dynamodb-local
    - serverless-offline

Run serverless offline start.

Other useful options

You can reduce the clutter generated by serverless-offline with --dontPrintOutput and disable timeouts with --noTimeout.

Run a function locally

To run your compiled functions locally you can:

$ serverless invoke local --function <function-name>

Options are:

  • --function or -f (required) is the name of the function to run
  • --watch - recompile and run a function locally on source changes
  • --path or -p (optional) path to JSON or YAML file holding input data
  • --data or -d (optional) input data

Enabling source-maps

You can easily enable support for source-maps (making stacktraces easier to read) by installing and using the following plugin:

yarn add --dev source-map-support
// inside of your function
import 'source-map-support/register'

If you are using webpack (most likely). Add devtool: 'source-map' to webpack.config.js:

module.exports = {
  .... snip ....
  devtool: 'source-map',
  .... snip ....

}
