How TypeScript Code Formatter Works
Format your TypeScript code in three simple steps
Paste Your Code
Copy your unformatted or messy TypeScript code and paste it into the input editor. The formatter supports standard TypeScript syntax and common formatting patterns.
Click Format
Hit the "Format Code" button and watch as our intelligent formatter instantly restructures your code with proper indentation, spacing, and TypeScript best practices.
Copy or Download
Your beautifully formatted code appears in the output panel. Copy it to your clipboard with one click or download it as a .ts file for immediate use in your projects.
TypeScript Code Formatting Best Practices
Writing clean, readable, and well-formatted TypeScript code improves maintainability, collaboration, and reduces bugs.
1. Consistent Indentation
Maintain a uniform indentation style throughout your code:
- Use 2 or 4 spaces per indentation level consistently.
- Avoid mixing tabs and spaces.
- Indent nested blocks, functions, classes, and interfaces for clarity.
2. Limit Line Length
Keep lines short for better readability:
- Recommended: 80–120 characters per line.
- Break long statements or type definitions into multiple lines.
- Helps readability across editors and devices.
3. Logical Spacing
Use blank lines to separate logical blocks:
- Separate functions, classes, and interfaces with empty lines.
- Add space around operators for clarity.
- Improves scanning of complex code and type declarations.
4. Meaningful Names
Choose descriptive and consistent names for readability:
- Variables: use camelCase like
userCount. - Functions: use descriptive verbs like
calculateTotal(). - Classes/Interfaces: use PascalCase like
UserProfileorIUser. - Enums: use PascalCase like
ColorType.
5. Use Type Annotations
Explicitly define types wherever possible:
- Type all variables, function parameters, and return types.
- Helps catch errors early during compilation.
- Improves code readability and documentation.
6. Follow Community Conventions
Adhere to established TypeScript style guides:
- Use Microsoft TypeScript Handbook or Airbnb TypeScript Style Guide.
- Use linters like ESLint with TypeScript plugin.
- Use Prettier for consistent formatting.
Before Formatting
async function fetchData(url:string):Promise<void>{try{let res=await fetch(url);let data=await res.json();console.log(data);}catch(err){console.error(err);}}fetchData('https://api.example.com');
After Formatting
async function fetchData(url: string): Promise<void> {
try {
let res = await fetch(url);
let data = await res.json();
console.log(data);
} catch (err) {
console.error(err);
}
}
fetchData('https://api.example.com');
Why TypeScript Formatting Matters
Proper formatting ensures your TypeScript code is easy to read, debug, and maintain. It improves collaboration within teams, ensures type safety, and helps automated tools like linters and formatters work effectively. Well-formatted code reduces errors, improves maintainability, and increases overall project quality.
- Readable code is easier to maintain and extend.
- Explicit types reduce runtime errors and improve IDE support.
- Supports automated tools like ESLint, Prettier, and TypeScript compiler.
- Encourages professional and consistent coding habits.
