TypeScript Formatter is a professional online code processing tool that supports formatting, minification, and validation of TypeScript and TSX code. Using Monaco Editor for powerful code editing experience, and integrating esbuild for efficient code minification.
All operations are performed entirely in your local browser, code is not uploaded to any server, ensuring your code security and privacy.
You can directly paste code, upload a file, or use example code. The editor supports syntax highlighting and auto-completion.
Set the indentation size (2/4/8 spaces) and whether to use spaces instead of tabs. These settings affect the formatted code style.
Click the 'Format' button to beautify the code for better readability; click the 'Minify' button to remove spaces and newlines to reduce code size.
After formatting or minification, click the 'Copy Result' button to copy the processed code to clipboard.
Uses prettier for code formatting, supports TypeScript and TSX code formatting.
All operations are performed locally in your browser, code is not uploaded to any server, fully protecting your privacy.
Supports custom indentation size, space/tab selection and other formatting options to meet different coding standards.
TypeScript has a complex type system including interfaces, generics, union types, etc. When minifying, type annotations must be handled correctly to ensure type inference and checking are not affected.
Using esbuild-wasm to run in the browser requires handling WASM module loading and initialization. The first load may require downloading the WASM file, requiring optimization of the loading experience.
Minified code must maintain functional integrity. Although spaces and comments are removed, code logic must remain unchanged, requiring precise AST parsing and transformation.
TypeScript is a superset of JavaScript, adding a static type system and other features. It performs type checking at compile time, helping developers find errors before runtime. TypeScript code must be compiled to JavaScript to run in browsers or Node.js.
Code formatting means automatically adjusting code indentation, line breaks, spaces, etc. according to coding standards to make code more readable and consistent. Common formatting tools include Prettier, ESLint, etc. This tool uses Monaco Editor's built-in formatting feature.
Code minification is the process of reducing code size by removing spaces, newlines, comments, and shortening variable names. Minified code maintains the same functionality but with reduced readability, mainly used in production to reduce file size and loading time.
A: TypeScript is a superset of JavaScript, adding features like type system, interfaces, enums on top of JavaScript. TypeScript code needs to be compiled to JavaScript to run, but can find type errors at compile time, improving code quality.
A: No. The esbuild minification tool maintains code functional integrity, only removing spaces, newlines, and comments, and possibly shortening variable names. Minified code has the exact same functionality as the original code, just with reduced readability.
A: The formatting tool uses Monaco Editor's default formatting rules. You can change the formatting style by adjusting the indentation size and space/tab settings. For more complex custom rules, it's recommended to use professional formatting tools like Prettier.
A: The first minification needs to download and initialize esbuild's WASM module (about 8MB), which may take a few seconds. After initialization, subsequent minification operations will be very fast. The WASM module is cached by the browser, so no need to download again on next visit.
