ESLint: Flat Config Rollout Plan

I don’t have my config readily available but just pick a default that’s close to what you want then make tweaks based on your preferences. It’s an incredibly useful tool for even a solo dev to keep your code looking consistent.

Having too many options leads to a lot of bikeshedding as the whole ecosystem ends up fragmenting and disagreeing with each other. It’s one of things I really dislike about JS compared to something like Go.

Personally, I stick to opinionated rulesets such as Standard[1], AirBnb[2] and Unicorn[3] since you won’t spend hours tweaking and selecting new rules.

Integrate it into your IDE, so you get yellow and red squigglies to attract your attention to potential issues - and set it up to fix any automatically solvable issues on save. And if you’re feeling ambitious, set it up to prevent git commit until ESLint detects no errors - and set up your pull requests to likewise reject merges until issues are fixed.

Usually you would pick a config you like and set it up for your project, notable ones are already mentioned but I'll mention xo[1] and @antfu/eslint-config[2].

There is an “eslint-recommended” rule set. (And a matching one for typescript-eslint).

I recommend those as they seem to be the least intrusive while giving a lot of sane defaults.
