Recommend .tsconfig

[mxdvl]

There are a few rules which are sadly no turned on by default, and it would be good to share a recommended .tsconfig for those interested.

For example:

• strict: true
• esModuleInterop: true
• noUncheckedIndexedAccess: true

  This flag can be handy for catching out-of-bounds errors, but it might be noisy for a lot of code, so it is not automatically enabled by the strict flag; however, if this feature is interesting to you, you should feel free to try it and determine whether it makes sense for your team’s codebase!

Is it possible to consume this in projects? Would you have to extend from node_modules directly?

It looks like you can extend from a package. TypeScript maintain a list of recommendations themselves: https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#tsconfig-bases
