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)
