Eliminate eslint-plugin-standard

[feross]

We are only using one rule at this point: no-callback-literal. It would be nice to see if there's some way to eliminate the dependency and simplify the maintenance burden in some way.

We are only using one rule at this point: no-callback-literal.

Couldn’t we replace it with handle-callback-err?

I would also like to say that this looks like an old JavaScript coding pattern that can be replaced by promises and async functions.

handle-callback-err is about ensuring that the error is always handled in node.js-style callbacks. E.g. this is an error:

function loadData (err, data) {
    doSomething()
}

no-callback-literal ensures that when a node.js-style callback is actually called, the first argument is always null, undefined, or an Error object. E.g. this is an error:

cb('an error string')

I opened an issue asking if ESLint wants to adopt no-callback-literal so we can deprecate eslint-plugin-standard: mysticatea/eslint-plugin-node#178
