This project:

• Defines and explains the coding style and workflow for the S3 project. See CONTRIBUTING.md for details.

• Provides an eslint-config-scality package that can be added as a dependency in other projects. That way, coding style can automatically be checked using eslint.

This repository also provides a baseline Prettier configuration for Scality object repositories: 4-space JavaScript/TypeScript indentation, 120-character line length, single quotes, semicolons, trailing commas, and quoteProps: 'as-needed'.

The configuration lives in prettier.config.cjs.

To use it in a project:

1. Install Prettier in the project:

   yarn add --dev prettier
   # or
   npm install --save-dev prettier

2. Copy or extend the configuration:

   // prettier.config.cjs
   module.exports = require('eslint-config-scality/prettier.config.cjs');

3. Add convenience scripts:

   {
     "scripts": {
       "format": "prettier --write .",
       "format:check": "prettier --check ."
     }
   }

Projects may override options locally (for example tabWidth or printWidth) if they have strong legacy constraints, but this configuration is intended to be the default Scality baseline for new or reformatted Node.js codebases. YAML/JSON/Markdown files default to a 2-space indentation and Markdown prose is left un-reflowed by default (proseWrap: 'preserve'), to avoid noisy diffs in existing documentation.
