@osdlc/prettier-config

A shared Prettier config: no semicolons, single quotes, trailing commas everywhere, 100 columns, two-space indent. Markdown is left alone (see below).

npm install --save-dev @osdlc/prettier-config prettier

Use

Name the package in your Prettier config. In package.json:

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

Or in a .prettierrc:

"@osdlc/prettier-config"

The quotes are required in .prettierrc: it is parsed as YAML, and a bare @ leading a plain scalar is reserved.

Markdown is not formatted

The config has exactly one override, and it exists to hand .md away rather than to style it:

{ "files": "*.md", "options": { "requirePragma": true } }

Prettier column-pads markdown tables on every pass, which fights a dedicated markdown formatter. Prettier has no way to exclude a language from config: overrides sets options, there is no ignore key, and excludeFiles only drops a file from that override's options. With requirePragma set, Prettier parses markdown and then declines to reformat any file that lacks a @format or @prettier pragma. A file that adds the pragma opts itself back in.

.mdx is still Prettier's: files: "*.md" does not match it.

Ignore files

.prettierignore is read from the directory Prettier runs in and does not cascade, so each project keeps its own. This package does not ship one.
