JavaScript / TypeScript in EGroupware

Our framework automatic loads for the current app automatic the JavaScript file $app/js/app.(min.)js.

Native ES6 module import and RollupJS

EGroupware master / next release after 21.1 moves from our privious LAB.js based loading and a require method for our TypeScript, to using native ES6 module import and RollupJS.

Our developer-install update script ./install-cli.php runs the following commands now after git pull for all repos:

compose install already the case since some time
npm install ---- " ----
grunt ---- " ----
npm run build running new rollup -c

For development, specially debugging JavaScript, you probably want to switch minifying off in rollup.config.js, otherwise you are not able to set breakpoints on some lines.

Use npm run build:watch or click on the green run icon in package.json opened in PHPStorm to automatic build changed files for developing.

Please note the following about ES6 modules:

the always use strict mode
this is undefined, use window instead eg. for wrapping

Migrating your TypeScript app.ts

fix import statements in TypeScript (they are not only to make tsc happy, but make sure dependencies get loaded and in scope)
no longer commit the generated .js script, as it only gives a lot of conflicts AND needs to be regenerated by rollup for every change in the whole EGroupware (not just your app!)
use the commits from our default apps as an example what's required
switch off automatic TS compiling in PHPStorm, it has to happen using RollupJS (npm run build:watch)

Migrating your old JavaScript app.js

preferable migrate your app.js to TypeScript using our migration script
if you don't want to migrate to TS right now, change the *egw:uses annotations to import statements like in the following commit for mail app.js
make sure your app.js is "use strict" compatible, as this is the default for JavaScript modules

Using the same app with 21.1 and master

If your app does not use a 21.1 branch and need to run in master and 21.1 AND already uses TypeScript, you need to keep the in 21.1 generated app.js and regenerate it in 21.1 when you change something in app.ts. RollupJS in master will rebuild it anyway, you only have to deal with the conflicts, if developing with multiple developers ;)
