While migrating to pnpm I got an issue with our extends relying on
node_modules. pnpm have only symlinks and do not have hoisted
node_modules in the root.
Here I switched extends to package name as all tools can resolve it and
tweaked remix tsconfig to extend from packages folder instead of
node_modules.
Right now our build and CI take a lot of time. 1:40min - 2min on CI and
1min locally. We spend time on vercel, on main CI, on publish and
locally.
At the moment in packages anything outside of src folder is not checked
because of rootDir.
We have to generate "references" field on precommit.
All these issues can be avoided if remove .d.ts generation completely
and specify sources in "types" field. This way we get zero build time
for types and can switch to other build tool (like esbuild) for .js
generation and get almost instant build on vercel, on main CI and on
publish.
Downsides
- it can be slower (actually not really caz we delete .tsbuildinfo cache
anyway and we can still generate it with incremental flag)
- it contraditcs recommended practices for published packages (we can
generate .d.ts in publish script only and use "types" as source
internally)
Our designer bundle heavily bloated with not analyzable commonjs
generated by typescript.
The biggest problem comes from bundled icons library which esbuild
cannot tree shake because of cjs.
Another issue is broken code splitting. Packages in one piece are appear
in chunks and always loaded even with dynamic import and React.lazy.
To solve this I migrated each package to native node es modules.
Storybook and jest work almost without changes. Though it's not possible
to run remix in esm project (while still esm packages can be bundled for
ssr). And as a result designer jest failed because of cjs tests requires
from esm packages. As a solution I generated additional commonjs
artifacts in lib/cjs.

Here "include" often have list of extensions and forgotten .tsx so such
modules are left unchecked. Replaced with just "src" which consider all
typescript extensions.
Ideally stop using tsc to build artifacts, switch to esbuild and remove
complex configuration from all tsconfig.json.
