@appmockup/node-render

Node adapter for AppMockup. Wraps @appmockup/core with a @napi-rs/canvas context (Skia, prebuilt binaries — no system libraries required), bundled fonts, image decode/encode, and batch generation. Backs both the CLI and the MCP server.

npm i @appmockup/node-render

API

• loadConfigFile(path) → { config, configDir }.
• validateConfig({ config, configDir }) → string[] of problems (headlines + files).
• renderOneToPng(opts) → { buffer, size, entry } for one screenshot × language × size.
• renderSceneToPng(scene) → PNG Buffer.
• generate(opts) → writes <outputDir>/<size>/<lang>/<prefix>_<lang>_<id>.png, returns paths.
• decodeImageBuffer(bytes) → a drawable ScreenshotImage (for uploaded/base64 input).
• ensureFontsRegistered() / fontsDir().

Screenshots come from disk (configDir + each entry's file) or from a pre-decoded images map keyed by screenshot id, which takes priority.

Fonts

Ships Inter + Noto Sans + Noto Sans Arabic in fonts/, auto-registered on first render so Node output matches the browser. Drop additional .ttf/.otf files in that dir to extend language coverage.
