Output - Deep Dive

Output is a JavaScript/TypeScript build package that wraps esbuild. It compiles VSCode TypeScript source and CodeEditorLand editor code into JavaScript bundles consumed by Sky, Wind, and Cocoon.

Architecture 🏗️

Two compiler modes: default esbuild pipeline and optional Rest (OXC-based) pipeline, selectable via environment variable.

Modules

Path
`Source/prepublishOnly.sh` - Main build entry script
`Source/Run.sh` - Development watch script
`Source/ESBuild/Output.ts` - esbuild programmatic configuration
`Source/ESBuild/RestPlugin.ts` - esbuild plugin delegating to Rest binary
`Source/ESBuild/Microsoft/` - VSCode platform bundle entry points
`Source/ESBuild/CodeEditorLand/` - Editor customization bundles
`Source/ESBuild/Exclude/` - Module exclusion rules
`Configuration/ESBuild/Microsoft/VSCode.js` - esbuild config for VSCode dependency
`Configuration/ESBuild/CodeEditorLand/Editor.js` - esbuild config for editor

Build Pipeline 🔧

Default path (esbuild):

esbuild reads TypeScript source from Dependency/Microsoft/VSCode/
esbuild resolves, bundles, tree-shakes
Output written to Target/Microsoft/VSCode/

Rest path (Compiler=Rest):

Rest binary compiles TypeScript to Target/Rest/Microsoft/VSCode/
RestPlugin.ts intercepts .ts files, invokes Rest subprocess
esbuild reads Rest output, applies bundling and merging
Final artifacts land in Target/Microsoft/VSCode/

Integration 🔗

Element	Direction	Mechanism
Rest	Consumer	Process invocation via RestPlugin
Sky	Provider	`@codeeditorland/output` npm package
Wind	Provider	`@codeeditorland/output` npm package
Cocoon	Provider	File path reference from Target directory

Configuration ⚙️

Variable	Default	Description
`Compiler`	`esbuild`	Set to `Rest` for OXC compilation
`REST_BINARY_PATH`	auto-detect	Override Rest binary location
`REST_VERBOSE`	`false`	Enable verbose Rest logging
`NODE_ENV`	`production`	`development` enables source maps

Rest mode runs 2-3x faster on TypeScript-heavy codebases but requires the Rest binary in the build environment.
