Shift.JS is a Swift-to-JavaScript transpiler built in JavaScript, with a lexer, parser, and AST-based code generation via Escodegen. It ships as an npm-installable CLI that converts Swift files to JavaScript and can watch files for changes.

Use cases

• transpile swift code to javascript
• convert a .swift file into a runnable js file
• reuse swift logic in a web browser
• watch a swift file and re-transpile on save
• learn how transpilers work via lexer and parser architecture

When to choose

• you have simple Swift code (data types, control flow, functions) you want to run as JavaScript
• you want an npm-based CLI for Swift-to-JS conversion
• you want to study or extend a transpiler codebase

When to avoid

• you need full Swift language or standard library support
• you need actively maintained tooling with a license and recent development
• you need iOS/native Swift compilation rather than transpilation
