fix: augmented type generation

[rflechtner]

fixes KILTProtocol/ticket#2576

We're not the only ones with that problem, and from issues on the polkadot-js/api repo I took that type augmentation can no longer be run in cjs. We are now required to add the --esm flag when calling ts-node and to add the "type":"module" to the package.json. Fearing that this may interfere with the dual cjs/esm code generation in our repo, and realising we do not actually need code, just types from the augment-api package, I have refactored the build process only of this package to just produce types (and a few dummy files required for importing them from different environments.

Along the way, I have also tackled two FIXMEs that we've had sitting there for a while now.

How to test:

I tried building and publishing with yalc and using the resulting package in stakeboard, which works fine. Could be tried in other projects using this package as well.

Checklist:

• I have verified that the code works
• I have verified that the code is easy to understand
  • If not, I have left a well-balanced amount of inline comments
• I have left the code in a better state
• I have documented the changes (where applicable)

Not too deep into all these JS/TS stuff, but it looks good. The only thing is that if I run yarn build in the root and then yarn build:types from within the augmentation package, the compiler still complains that src/interfaces/extraDefs/types.ts cannot find the name PalletDidLookupLinkableAccountLinkableAccountId, and in the diff I can see the old FIXME is gone. Is that expected? Is it just my own VSCode compiler issue?

[ntn-x2]

Is this auto-generated? Why do we have a change from AccountId32 to AccountId20 here?

[rflechtner]

yeah we haven't been able to run type generation on this polkadot version, so this has been outdated until now

[ntn-x2]

I get a linter error that the header is missing.

[rflechtner]

weirdly, I don't ?

[rflechtner]

added the header nevertheless

[ntn-x2]

Same as above.

It's 'expected' - that we once introduced a manual fix to an autogenerated file means that we'll have to reapply this fix every time after autogeneration, which in most cases just means reverting the change to this line.
