eslint-config-firecloud

The ESLint config used within Tobii Cloud Services.

In your project's .eslintrc.js

module.exports = {
  extends: [
    'firecloud/node'
  ],
  rules: {
    'override-some-rule': error
  }
}

Optionally, you can run node_modules/eslint-config-firecloud/npm-install-peer-dependencies in order to install the required peer dependencies.

If you want to use an addon, it's as easy as doing this in .eslintrc.js:

module.exports = {
  extends: [
    'firecloud/node',
    'firecloud/configs/jest'
  ],
  rules: {
    'override-some-rule': error
  }
}

and running npm install --dev eslint-plugin-jest.

Bundles

Common bundles are provided as following:

• Node.js: firecloud/node
• Browser: firecloud/browser

These addons require you to install the plugin manually:

• @typescript-eslint/eslint-plugin: firecloud/configs/typescript
• eslint-plugin-jasmine: firecloud/configs/jasmine
• eslint-plugin-jest: firecloud/configs/jest
• eslint-plugin-mocha (with Chai): firecloud/configs/mocha
• eslint-plugin-protractor: firecloud/configs/protractor
• eslint-plugin-vue: firecloud/configs/vue

Guiding Principles

"I (don't) like/want ..." is no argument in this codebase. Instead, we follow a few guiding principles that have concrete consequences on daily work.

1. Keep It Short

• lines
• functions
• modules

2. Reduce Merge Conflicts

• do less on the same line
• break array/object expressions/patterns
• break import specifiers
• break conditions

3. Reduce Cognitive Load (via explicit code)

• even if code becomes more verbose

4. Reduce Dependency (on specific ecma versions)

• use a transpiler like babel (for syntax)
• use a utility library like lodash-firecloud (for functionality)

5. Increase Consistency

• don't use arrow functions when you don't need them
• don't use template literals when you don't need them
