* Remove webServer
First draft; I may move some things around to be more readable.
* Refactor moved code
1. Move StartSessionOptions to common next to where it's first used.
2. Inline single-use BaseLogger base class into its only child class,
Logger.
3. Start using direct imports, eg `import {} from './common'`. I hope
this is OK?!
* Fix lint
* move imports back to namespace import
* hereby tsserver: remove exportIsTsObject
It turns out that the import expression won't actally be rewritten by
esbuild, so we can just write it directly.
While this won't help CJS emit, that already didn't work anyway, and
it's likely that this code is going to be moved outside of the codebase
into VS Code or a shared package elsewhere anyway.
This debug code was added quite a while ago, constructed such that we
wouldn't have to ship this code to our users.
However, this is the sole place in the compiler project where the ts
namespace "escapes" the bundle. By moving this debug code into the
compiler itself, we no longer have any references to the ts namespace
itself for our bundles that don't export anything (tsc,
typingsInstaller). This lets bundlers tree shake the compiler, reducing
the size of our output by _5.7 MB_ (a ridiculous improvement for
_adding_ code).
needsUpdate may be wrong when the branch changes; these ones are now so
fast thanks to being pure JS that we can just always run their contents
and be sure that the outputs are right.
This eliminates a significant number of dependencies, eliminating all
npm audit issues, speeding up `npm ci` by 20%, and overall making the
build faster (faster startup, direct code is faster than streams, etc)
and clearer to understand.
I'm finding it much easier to make build changes for the module
transform with this; I can more clearly indicate task dependencies and
prevent running tasks that don't need to be run.
Given we're changing our build process entirely (new deps, new steps),
it seems like this is a good time to change things up.
