How to setup StandardJS lint

The npm packages

First install this packages as dev dependencies

npm i -D eslint eslint-config-standard eslint-plugin-import eslint-plugin-node eslint-plugin-promise eslint-plugin-standard

#or

yarn add -D eslint eslint-config-standard eslint-plugin-import eslint-plugin-node eslint-plugin-promise eslint-plugin-standard

Next step is add this flag to your .eslintrc.json:

"env": {
    "commonjs": true,
    "es6": true,
    "node": true
  },
  "extends": "standard"

How to use in code

In your code you'll use single quotes (') and omit the semicolon (;) like this:

const moment = require('moment')

module.exports = app => {
  const getTasks = (req, res) => {
    const date = req.query.date
      ? req.query.date
      : moment()
        .endOf('day')
        .toDate()

    app
      .db('tasks')
      .where({ userId: req.user.id })
      .where('estimateAt', '<=', date)
      .orderBy('estimateAt')
      .then(tasks => res.json(tasks))
      .catch(err => res.status(400).json(err))
  }

  return { getTasks }
}

If you're using VS Code and Prettier, add this option on your settings.json: "prettier.eslintIntegration": true
