Extend recommended React Native TSConfig base

[leotm]

Context

• Update es2017 to es2019 in React Native base tsconfig/bases#116

To keep our recommended React Native TSConfig base as the source

---

yarn set version classic

• Add devdep
• Extend
• Doc
• Remove ts --init comment boilerplate (can still remove further)
• Remove es2019 override
• Remove forceConsistentCasingInFileNames override

Have a think if skipLibCheck should be recommended for React Native, we do in few others

Remove duplicate rule overrides
Keep duplicate rule overrides for visibility

Hi, can you update this branch with master and see if it runs the lint action?

[leotm]

sure ^ how do you feel about what @orta mentioned btw

[leotm]

also considering if it's ideal for each dupe (non-unique) config to be commented (that it's extended) for visibility

or for simplicity remove the dupes alltogether

[orta]

Yeah, IMO, you should present an empty tsconfig if you're going with the extends

[leotm]

from messing around earlier

Preview: (Extended)

but sure an empty tsconfig w extends makes sense, i'll go ahead and remove the tsc --init commented boilerplate

[leotm]

done ^ much more minimal

happy to remove the rest of the comments still if we want near-fully empty tsconfig

[leotm]

and happy to remove any overrides like es2019 once merged in
