# cURL to JavaScript (fetch) Converter Convert a cURL command into a JavaScript fetch() code snippet with headers, body, and method > Canonical page: https://elysiatools.com/en/tools/curl-to-js-fetch - **Category:** Development - **Keywords:** curl, convert, javascript, js, fetch, http, api, code generator, snippet, node ## Overview Quickly convert your cURL commands into clean, ready-to-use JavaScript fetch() code snippets. This tool automatically parses HTTP methods, headers, and request bodies from your cURL syntax, generating standard JavaScript code for browser or Node.js environments. ## Inputs - **cURL Command** (textarea): curl -X POST https://api.example.com/users \ -H "Content-Type: application/json" \ -d '{"name":"Alice"}' - **Pretty-print body** (checkbox) - **Include comments** (checkbox) ## When to use - When migrating API requests tested in the terminal via cURL into a frontend web application using the native Fetch API. - When debugging API integrations and needing to quickly translate third-party documentation cURL examples into JavaScript. - When building Node.js scripts or browser scripts that require structured HTTP requests with custom headers and JSON payloads. ## How it works - Paste your raw cURL command into the input text area. - Toggle options to pretty-print the request body or include explanatory comments in the output. - Copy the instantly generated JavaScript fetch() code snippet from the output field. ## Use cases - Translating API documentation examples written in cURL into frontend JavaScript code. - Converting terminal-based API tests into reusable JavaScript functions for web applications. - Generating fetch requests with complex headers and authentication tokens for rapid prototyping. ## Frequently asked questions ### Does this tool support POST requests with JSON payloads? Yes, it parses the data flags and converts them into the body of the fetch request. ### Can I format the output JSON body? Yes, enabling the 'Pretty-print body' option formats the JSON payload for better readability. ### Does it support custom headers? Yes, all headers specified with the -H or --header flags are extracted and added to the fetch headers object. ### Can I use the generated code in Node.js? Yes, the generated fetch() code works in modern Node.js environments as well as standard web browsers. ### Are comments included in the generated code? Yes, you can toggle the 'Include comments' option to add helpful annotations to the generated snippet. ## Related tools - [cURL to Go (net/http) Converter](https://elysiatools.com/en/tools/curl-to-go): Convert a cURL command into a Go net/http code snippet with http.NewRequest, headers, and body - [cURL to JavaScript (axios) Converter](https://elysiatools.com/en/tools/curl-to-js-axios): Convert a cURL command into a JavaScript axios code snippet with config object, headers, and data - [cURL to PHP (cURL) Converter](https://elysiatools.com/en/tools/curl-to-php): Convert a cURL command into a PHP cURL code snippet with curl_setopt, headers, and post fields - [cURL to Python (requests) Converter](https://elysiatools.com/en/tools/curl-to-python): Convert a cURL command into a Python requests code snippet with headers, data, and method - [API Contract Stress Tester](https://elysiatools.com/en/tools/api-contract-stress-tester): Generate boundary-value test cases from an OpenAPI 3.x document and optionally send them to a real backend to spot contract mismatches - [Cron Expression Explainer](https://elysiatools.com/en/tools/cron-expression-explainer): Parse a 5-part / 6-part / Quartz cron expression into a plain-language schedule description, show the field-by-field breakdown, and list the next N execution times in any IANA timezone — with an AI-generated natural-language explanation in your language - [Tailwind Color Palette Sync](https://elysiatools.com/en/tools/tailwind-color-palette-sync): Generate theme.extend.colors for tailwind.config.ts from HEX colors, with WCAG contrast levels and optional dark mode. - [cURL Command to HAR Converter](https://elysiatools.com/en/tools/curl-to-har-converter): Convert a cURL command into a portable HAR 1.2 request entry. ## Samples - [Rome JavaScript Toolchain Samples](https://elysiatools.com/en/samples/rome): Rome JavaScript toolchain examples including configuration, linting, formatting, bundling, and project management - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Hugging Face JavaScript Samples](https://elysiatools.com/en/samples/huggingface-js): Hugging Face JavaScript/TypeScript examples using Transformers.js for NLP, computer vision, and multimodal tasks in browser and Node.js - [JavaScript Samples](https://elysiatools.com/en/samples/javascript): Essential JavaScript code examples and Hello World demonstrations ## Related content - [cURL API Request Conversion and Testing](https://elysiatools.com/en/hubs/curl-to-code-converter): Convert a cURL request into code or HAR, test it safely, and explain the HTTP status without losing headers, body, or auth context. - [API Request Format, Replay Preparation, and Debugging Tools](https://elysiatools.com/en/hubs/api-request-replay-and-debugging): Check request structure, prepare a local replay, compare responses, and debug API clues.
