Bolt CEP is a comprehensive boilerplate for building Adobe Common Extensibility Platform (CEP) extensions using modern web technologies. It provides a unified development experience for creating extensions that work across Adobe applications like Photoshop, Illustrator, Premiere Pro, and After Effects. The system features a monorepo structure containing the core boilerplate, a project creation CLI (create-bolt-cep), and a specialized Vite plugin (vite-cep-plugin) that handles CEP-specific build tasks. Developers can choose between React, Vue, or Svelte for their frontend framework while writing type-safe ExtendScript that compiles down to ES3 for CEP compatibility. Key innovations include an end-to-end type-safe bridge between CEP JavaScript and ExtendScript (via evalTS/listenTS/dispatchTS), automated ZXP packaging with cross-platform signing support, and intelligent asset handling. The build process leverages Vite for fast HMR during development and Rollup for producing CEP-compatible ExtendScript bundles.
