- Instead of building index.js with esbuild and generating types with
tsc, use tsc to build index.js and index.d.ts.
- Use ts-node instead of swc for typescript based tests, as that
works with es modules.
- Remove "syntax_check" target from package.json as that's now
implied with "compile".
- Sadly this requires one "as any" cast as tsc somehow fails to
determine the right type info for node-fetch.
Unfortunately index.js can't be an ES module without breaking
compatiblity. It would imply that the Node.js port can't be used with
require() anymore. So even thought that would simplify things further,
it's not part of this PR.
Share tsconfig.json so that ava runs the typescript compiler also on the tests.
Similary, the syntax check now also covers the tests.
Sadly, the exception that the Slint compiler throws is not type declared,
so we have to use any.
Similarly, the object share returned by loadFile() is unknown
in terms of properties, callbacks, etc.
