Webpack plugin for Google Apps Script.

About

In Google Apps Script, an entry point called from google.script.run must be a top level function declaration on the server side. gas-webpack-plugin detects function assignment expressions to global object and generate a corresponding top level function declaration statement.

example

main.js:

var echo = require('./echo');
/**
 * Return write arguments.
 */
global.echo = echo;

echo.js:

module.exports = function(message) {
  return message;
}

webpack.config.js:

const GasPlugin = require("gas-webpack-plugin");
module.exports = {
  context: __dirname,
  entry: "./main.js",
  output: {
    path: __dirname ,
    filename: 'Code.gs'
  },
  plugins: [
    new GasPlugin()
  ]
}

build:

$ webpack --mode production

Options

You can pass a hash of configuration options to gas-webpack-plugin. Allowed values are as follows

Name Type Default Description
comment {Boolean} true If true then generate a top level function declaration statement with comment.
autoGlobalExportsFiles {Array<String>} [] Array of source file paths that to generate global assignments expression from exports.* statements.
include {Array<String>} [**/*] Array of path patterns to detect functions to generate top level function definitions. accept glob pattern.

Geranate global assignment expressions from exports.*

Assignments expression to global object is automatically generated from named exports (exports.*) Included in the file specified by the autoGlobalExportsFiles option.

main.ts:

import './echo';

echo.ts:

// geranate global assignment expressions from named export
export const echo = (message) => message;

webpack.config.js:

const GasPlugin = require("gas-webpack-plugin");
module.exports = {
  context: __dirname,
  entry: "./main.ts",
  module: {
    rules: [
      {
        test: /(\.ts)$/,
        loader: 'ts-loader',
      },
    ],
  },
  resolve: {
    extensions: [".ts"],
  },
  output: {
    path: __dirname ,
    filename: 'Code.js'
  },
  plugins: [
    new GasPlugin({
      autoGlobalExportsFiles: ['**/*.ts']
    })
  ]
}
