gulp-gsuite-typescript

A gulp plugin to make google apps script project works as a normal typescript project.

If you want to develop GSuite Addon Apps with typescript, gulp & gulp-gsuite-typescript can help you out with all typescript feature enabled.

Install

yarn add gulp-gsuite-typescript -D

How it works

1. Transpile typescript files one by one with ts2gas the tool from Google.
2. Rename .ts ext to .js.

Usage

const { src, dest } = require('gulp');
const { trans } = require('gulp-gsuite-typescript');

function build(cb) {
  src('src/**/*.*', { base: './src' })
    .pipe(trans())
    .pipe(dest('./built'));
  cb();
}

exports.build = build;

Notes

When there're consts or variables you want to export, the export statement have to be written like export { CONST_1, CONST_2 };.

Here's why:

const REQUEST_HOST = 'https://www.someapi.com';
const const REQUEST_VERSION = '1.0';
 
export { Utils, REQUEST_HOST };

After it's transpiled:

// Compiled using ts2gas 3.4.4 (TypeScript 3.6.4)
var exports = exports || {};
var module = module || { exports: exports };
var REQUEST_HOST = 'https://www.someapi.com';
exports.REQUEST_HOST = REQUEST_HOST;
exports.REQUEST_VERSION = '1.0';

After transpiled REQUEST_HOST has var REQUEST_HOST = 'https://www.someapi.com' and exports.REQUEST_HOST = REQUEST_HOST;. But REQUEST_VERSION has only exports.REQUEST_VERSION = 1.0;.

There's no way that REQUEST_VERSION can be found in a globle scope in GSuite addon app.
