@starci/prettier-config

The one StarCi Prettier config, for back end and front end. Prettier is the only formatter: the ESLint layout rules (indent, quotes, semi, object-curly-newline, array-element-newline, function-call-argument-newline) are removed from the canon and never come back.

{ "prettier": "@starci/prettier-config" }

Install it from the npm registry at the exact version in knowledge/hfs/canon-pins.yaml (see packages/README.md).

The choice

printWidth: 120, tabWidth: 4, semi: false, singleQuote: false, trailingComma: "all"; JSON, YAML and Markdown use 2 spaces.

None of the StarCi monorepo repositories carries a Prettier file today. Their layout came from ESLint: the largest back end enforces indent: 4, quotes: "double", semi: "never", and the front-end sources already follow the same four rules. The largest repository's dialect produces the smallest reformat diff. What changes is the one-binding-per-line imports and exports and the one-argument-per-line calls those ESLint rules forced; Prettier collapses them to the width. endOfLine is auto so a Windows checkout with core.autocrlf is not flagged.

Applying it to a large repository is one commit in a quiet window, listed in .git-blame-ignore-revs.
