Question 1

How to set up Airbnb style guide with ESLint in my project?

Accepted Answer

Install eslint-config-airbnb-base for vanilla JavaScript or eslint-config-airbnb for React via npm, then extend it in your .eslintrc file. The README includes ESLint rule references for each guideline to automate enforcement.

Question 2

Airbnb style guide vs StandardJS: which is better for a new project?

Accepted Answer

Airbnb's guide is more comprehensive and opinionated, ideal for teams wanting strict consistency and modern practices. StandardJS is simpler with fewer rules, better for projects favoring minimal configuration and automatic formatting.

Question 3

Does Airbnb style guide support TypeScript or only JavaScript?

Accepted Answer

It's primarily for JavaScript, but community adaptations exist for TypeScript. You can use ESLint plugins to apply similar rules, though it requires extra configuration and might not cover all TypeScript-specific features.

Question 4

How to override a specific rule I disagree with in Airbnb ESLint config?

Accepted Answer

In your ESLint configuration file, you can override any rule by setting it to 'off' or adjusting its options. The README lists ESLint rule names per section, making it easy to identify and customize rules like 'arrow-parens'.

Question 5

Why does Airbnb prefer const over let for variable declarations?

Accepted Answer

To prevent accidental reassignments and improve code predictability, as explained in section 2.1, which highlights that const ensures references remain immutable, reducing bugs.

Question 6

Is Airbnb style guide suitable for Node.js backend code?

Accepted Answer

Yes, it's framework-agnostic and works for any JavaScript environment, including Node.js. Use the base ESLint configuration without React-specific rules, and it covers modules and standard library usage relevant to backend development.
