Shikiji is an ESM-focused rewrite of the Shiki syntax highlighter, using TextMate grammars (the same engine as VS Code) to produce accurate, beautiful code highlighting. It is fully tree-shakable, runs on any JavaScript runtime, and supports HAST-based customization; it has since been merged back into Shiki and archived.

Use cases

• highlight code blocks in a static site generator
• render syntax-highlighted code with zero runtime JavaScript
• highlight code in Cloudflare Workers or edge runtimes
• customize code highlighting output via HAST transformations
• use VS Code TextMate grammars for accurate highlighting in docs
• highlight code in a markdown pipeline

When to choose

• you need accurate, VS Code-grade syntax highlighting in an ESM-first JavaScript project
• you want tree-shakable highlighting that runs in browsers, Node.js, or edge workers
• you need fine-grained customization of the highlighted output

When to avoid

• starting a new project - use shikijs/shiki instead, since Shikiji is archived and merged back into Shiki
• you need a CommonJS-only environment without ESM support
• you need runtime highlighting of arbitrary languages with minimal bundle size
