{"id":20353,"library":"prettier-plugin-ejs","title":"Prettier Plugin for EJS","description":"A Prettier plugin that formats EJS (Embedded JavaScript) templates within HTML files. Current stable version 1.0.3 supports Prettier 2.x and 3.x. It works by marking EJS tags as comments and relying on Prettier's built-in HTML parser, so it does not have its own parser — this keeps it lightweight but means EJS tags containing `>` are ignored. Compared to alternatives like prettier-plugin-ejs-by-ecmel, this is the most popular and maintained option. Release cadence is irregular, with infrequent updates; the plugin has been stable for years without major changes.","status":"active","version":"1.0.3","language":"javascript","source_language":"en","source_url":"https://github.com/ecmel/prettier-plugin-ejs","tags":["javascript","prettier","plugin","ejs","html"],"install":[{"cmd":"npm install prettier-plugin-ejs","lang":"bash","label":"npm"},{"cmd":"yarn add prettier-plugin-ejs","lang":"bash","label":"yarn"},{"cmd":"pnpm add prettier-plugin-ejs","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"Peer dependency required for plugin functionality","package":"prettier","optional":false}],"imports":[{"note":"This is a Prettier plugin, not a JavaScript module.
