FunPack

Funpack is a bundler specifically for better writing cloud functions(aka, a project that has multi entrypoints). It allows you to share common logic between isolated functions, and have a better development experience.

Basic

Your project folder should follow this structure:

root
├── funpack.config.js
├── package.json
├── src
│ ├── functions
│ │ ├── register
│ │ │ ├── config.json
│ │ │ └── index.ts
│ │ └── user-info
│ │ ├── config.json
│ │ └── index.ts
│ ├── types.ts
│ └── utils.ts
└── tsconfig.json

• funpack.config.js:config file forfunpack
• src/functions:all your functions are under this folder
  • src/functions/[fnName]/index.ts:function entry file
  • src/functions/[fnName]/[non-ts-file]:any non-ts file will be copied to output without modify
• src/[shardFile].ts:shard files should be outside of functions folder

Install

Install with npm:

npm install --save-dev @funpack/cli

Install with yarn:

yarn add @funpack/cli --dev

Templates

• wxmini-cloud:a template for wechat miniprogram cloud functions development

Commands

• funpack --watch:Build and watch functions
• funpack:Build functions (Setprocess.env.NODE_ENVto 'production' if you want production build)

funpack.config.js

This file need export default a config object:

interfaceUserFunpackConfig{
output?:{
/**
* functions will output to `projectRoot/[dir]/functions`
*
* default: dist
*/
dir?:string;

/**
* soucemap config, check https://webpack.js.org/configuration/devtool/#devtool for available values
*
* default: NODE_ENV == 'production'? "hidden-source-map": "eval-source-map"
* */
sourceMap?:string|false;
};

bundle:{
/**
* config output strategy
* if true, node modules used by function will be bundled,
* if false, package.json will be generated under every function
*
* default: true
*/
singleFile?:boolean;
};
}
