cURL to code

Paste a curl command and get fetch, axios, requests, or net/http. Headers, JSON, and basic auth stay in the request.

Code

Why this exists

A curl sample in an API doc is easy to retype badly. A header or a JSON field goes missing, and the request fails for a reason that is hard to see.

Keeping the URL, method, headers, JSON body, and basic auth in the language you actually ship lets you paste the request and edit it.

  1. 01How to use it

    Paste a command that starts with curl, or press Example. Changing the language rewrites the code.

    An unclosed quote or a missing URL is explained above the result.

  2. 02What you get

    The example creates a user with POST. The content type, bearer token, and JSON body land in each language.

    Any option the code does not carry is listed above it.

    EnteredCreate a user

    Method POST
    URL https://api.example.com/v1/users
    Body JSON

  3. 03Worth knowing

    Flags that only change how curl runs, such as -L, -s, and -k, stay out of the request. Retries, proxies, and file uploads do too.

    Split a command larger than 5MB. Read the URL and the token in the generated code before you commit it.

Questions

QDoes the command leave this browser?
ANo. Conversion stays on the page, and the curl text is not stored.
QWhich languages are generated?
AJavaScript fetch, axios, Python requests, Node.js 18 fetch, and Go net/http.
QWhat happens to basic auth?
APython gets an auth tuple. Fetch, axios, Node, and Go get an Authorization: Basic header.
QCan a form upload become code?
A-F and -T are not turned into a body. They are listed as options the code skips.

How this page works it out

A curl command pasted on this page is rewritten as JavaScript fetch, axios, Python requests, Node.js 18+ fetch, and Go net/http.

Basic authentication becomes the requests auth tuple in Python and a Basic authorization header in the fetch forms.

Multipart -F, output -o, upload -T, and similar flags are not turned into a request. The page ignores those flags and names each one. A command that is not curl is an error, and every quote must close.

The pasted command is converted only in this browser. It is not sent away to be rewritten.
