Sorry for the very big commit that may lead to git log issues and merge conflicts, but it's a major step forward: * Server can be faster at startup because imports() are async and we can easily lazy import big modules * Angular doesn't seem to support ES import (with .js extension), so we had to correctly organize peertube into a monorepo: * Use yarn workspace feature * Use typescript reference projects for dependencies * Shared projects have been moved into "packages", each one is now a node module (with a dedicated package.json/tsconfig.json) * server/tools have been moved into apps/ and is now a dedicated app bundled and published on NPM so users don't have to build peertube cli tools manually * server/tests have been moved into packages/ so we don't compile them every time we want to run the server * Use isolatedModule option: * Had to move from const enum to const (https://www.typescriptlang.org/docs/handbook/enums.html#objects-vs-enums) * Had to explictely specify "type" imports when used in decorators * Prefer tsx (that uses esbuild under the hood) instead of ts-node to load typescript files (tests with mocha or scripts): * To reduce test complexity as esbuild doesn't support decorator metadata, we only test server files that do not import server models * We still build tests files into js files for a faster CI * Remove unmaintained peertube CLI import script * Removed some barrels to speed up execution (less imports)
