    prettier-eslint

    Formats your JavaScript using prettier followed by eslint --fix

    The fix feature of eslint is pretty great and can auto-format/fix much of your code according to your ESLint config. prettier is a more powerful automatic formatter. One of the nice things about prettier is how opinionated it is. Unfortunately, it's not opinionated enough and/or some opinions differ from my own. So after prettier formats the code, I start getting linting errors. This formats your code via prettier, and then passes the result of that to eslint --fix. This way you can get the...

    Expressive middleware for node.js using ES2017 async functions

    Koa is a minimal, expressive web framework for Node.js created by the team behind Express, built around modern JavaScript features.

The framework exposes a refined Context object to standardize request and response utilities without obscuring Node’s primitives. ...
