This file is pretty much the same as it was when it was committed in
2017; these days, we can write clearer code with async/await and new FS
APIs.
Additionally, we can improve the performance of this script by using a
newer/faster/maintained XML library. This will enable us to run the
script unconditionally in a later commit.
Profiling the build roughly half of the time spent loading the
build is spent importing typescript.js, for this one function.
Since this stack is already adding required devDependencies, switch
readJson to use jsonc-parser (published by the VS Code team), rather
than importing the entire LKG typescript.js library.
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.
This configures the existing build tasks to use esbuild by default. If
using the plain files is desired, passing `--bundle=false` will build
using plain files and still produce a runnable system.
This is only a basic build; a more efficient build is provided later
when gulp is replaced by hereby.
