Alibaba f2e‑spec is a publicly‑available coding‑style and engineering‑process specification for front‑end development inside Alibaba’s ecosystem. It provides detailed guidelines (JavaScript, TypeScript, React, Node, CSS, HTML, Git, documentation, etc.) together with a bundled CLI/tool (F2ELint) that installs and runs the corresponding ESLint, stylelint, commitlint and markdownlint rule sets, letting teams quickly enforce the standards in their projects. The project is aimed at front‑end engineers and development teams who want a unified, opinionated style guide and automated linting/commit‑checking tooling.
