How We Keep Code Clean at Zaengle

Let's be honest, we all like systematic, uniform code.

However, maintaining a respectable level of cleanliness across multiple developers' systems can be a challenge. Thankfully there are a few tools to help unify our editors so that our code styling gets along!


ESLint enforces rules across our javascript files and is configurable via simple declarations.

Install the required packages:

yarn add eslint eslint-plugin-vue babel-eslint --dev

It's likely the each project will have unique linting needs, but we've had good luck using this as a starting point. Create a file at the root of your project called .eslintrc.json with the following code:

  "extends": [
  "rules": {
    "no-console": 1,
    "indent": [
  "parserOptions": {
    "parser": "babel-eslint"

PHPStorm should automatically pick up the .eslint configuration and begin displaying warnings/errors. If it does not, make sure ESLint is enabled in your PHPStorm preferences.


EditorConfig is a standard to share generic settings across multiple editors. Check here to see if your preferred editor supports the .editorconfig file.

Things like tab/spaces, indentation, and line-break preferences are specified in a single document called .editorconfig which is placed in the root of your project.











Setting Up PHPStorm

Most of the developers at Zaengle use PHPStorm so these instructions are specific to that platform. (You can still use ESLint and EditorConfig in other editors but you are on your own to figure them out!)

  1. Check that the snippet above is in a .editorconfig file at the root of your project.
  2. Search the plugin repository for "editorconfig" and install the plugin titled "EditorConfig".
  3. Visit Preferences / Code Style and confirm Enable EditorConfig support is checked.

Your code style settings should now use the team-wide defaults laid out in the config file!

In addition to the .editorconfig file you should configure the following items manually:

Gotcha: Managing Default Block Indentation

The plugin:vue-recommended rules require that javascript not be indented within a script tag and PHPStorm indents it by default. Thankfully we can override which items should not be indented like this:

  1. Visit Preferences / Code Style / HTML / Other and look for the Do not indent children of: setting.
  2. Remove thead, tbody, and tfoot.
  3. Add script.
  4. Save your change

Applying Formatting

There are two ways to apply formatting to your code in PHPStorm:

    Method #1 - Press cmd + option + l to apply the .editorconfig formatting and specific block indentation.

    Phpstorm Reformat

    Method #2 - Place your cursor over a section that has an error/warning highlight and press option + return to bring up a dialog. Select ESLint: fix current file to apply the styles specified in the .eslintrc.json file.

    Fix Current File


    With a few simple tools and customizations to our editors we've come a long way in code uniformity!
