feat: support .eslintrc

[ericclemmons]

Similar to #23.

Example:

Hmmm, maybe not. This looks like it's not easily discernible what all of the dependencies are, because of extends:

https://github.com/airbnb/javascript/tree/master/packages/eslint-config-airbnb

[ericclemmons]

It may be possible since peerDependencies are auto-installed now...

[ericclemmons]

I don't know how I feel about this. It's nice that it's automated, but only know of a handful of examples using extends.

@insin @poeticninja @bebraw What do you think? It certainly lowers the barrier for starting a project (e.g. Add .babelrc, .eslintrc, and start coding), but would want to stop supporting "external tools" at just Babel & ESLint.

[ericclemmons]

Examples to support:

• Extends eslint:recommended
• Extends airbnb
• Extends [ "airbnb", "eslint:recommended" ] (e.g. multiple configs)
• Extends @highereducation/eslint-config

[bebraw]

@ericclemmons It's a niche case for sure. Probably supporting Babel and ESLint for now gets you far. Accept the rest as PRs. 👍

[poeticninja]

Pretty much everyone that is using ESLint (that I have seen) are extending from some other place because there are a lot of rules. Very very few people are actually writing their own rules (I did once and not again). I think supporting extends is important to support ESLint.

[ericclemmons]

Cool, I think I got this functional. If you guys wanna give it a shot, go for it!

Coverage increased (+0.5%) to 93.956% when pulling b74202c on 36-eslint into 7649f30 on master.

I just tested it out with example/webpack1. I ran npm start... it installed all of the dependencies. After that I created an .eslintrc file with configurations extending airbnb as a test. I had to turn off and run npm start again for the install to take place again. BUT it worked!! 👍

[ericclemmons]

Here's a good test for ya:

https://www.npmjs.com/package/eslint-config-airbnb

This thing has so many peerDependencies and requirements it's absurd.

[ericclemmons]

@insin What do you think about this feature? Otherwise I'm considering closing it...

[michael-ciniawsky]

There are more possible formats with extensions for e.g .eslintrc.yml, .eslintrc.js and so forth

[michael-ciniawsky]

Would this be really needed ?

[alexander-akait]

@michael-ciniawsky imho, seems no
