⭐ Support ESLint 8.

• eslint-config-standard (feat: support eslint v8 standard/eslint-config-standard#193)

---

New eslint rules with typescript-eslint equivalents:

• no-loss-of-precision

New rules worth considering:

• no-unnecessary-type-constraint
• no-unsafe-argument

---

Refs:

• Changes to the recommended sets for 5.0.0

I didn't have time going through all entries of what typescript-eslint actually recommends in their recommended config. My gut tells me that it might be worth giving it a glance though - there might be some useful rules that we've missed.

standard/eslint-config-standard#193 has been merged. What does the process look like for this issue here, and is there some way to help?

[xCykrix]

Would definitely like some news on getting this merged so I can update my toolchain. Is there anything that could be assisted with to get this rolling @sQVe ?

[sQVe]

@xCykrix The first thing we would need to resolve is to update the dependencies for eslint@8. After that I feel think it would be great to have some consideration on the new rules that we could add.

We wil add support for ESLint v8, when eslint-config-standard v17 has been released stable.

[sQVe]

@divlo Until then it might make sense to have a discussion about the rules that applies only for TypeScript land?

[theoludwig]

Sure we can! @sQVe

Maybe in different issues to make it more maintainable.

@sQVe maybe you could make a next release that includes the next version of eslint-config-standard? So we could start testing it out and reporting any issues 🙏

When npm i -D eslint-config-standard@next

Could not resolve dependency:
npm ERR! peer @typescript-eslint/eslint-plugin@"^4.0.1" from eslint-config-standard-with-typescript@21.0.1

this means eslint-config-standard-with-typescript need to update deps to come up with eslint-config-standard@next
