Code generation

Nouto turns the open HTTP request into a snippet for one of 11 HTTP clients, so you can paste the call into a script or an app. A twelfth target, TypeScript Types, infers TypeScript interfaces from JSON in the request body.

Generate a snippet

1. Open an HTTP request and enter a URL. The Code button stays disabled while the URL is empty.
2. Click Code next to Send.
3. In the Generate Code dialog, select a target.
4. Click Copy to Clipboard.

In VS Code, Open in New Tab opens the snippet in an editor tab. In the desktop app, the same button copies the snippet to the clipboard. Nouto remembers the last target you selected.

Caution

Nouto resolves {{variables}} from the active environment before it generates the snippet. The code contains the real values, including tokens, passwords, and API keys. Check the snippet before you share it.

To copy a saved request as a cURL command without opening it, right-click the request in the sidebar and select Copy as cURL.

Targets

The Generate Code dialog lists these targets:

Target	Output
cURL	curl command for bash, zsh, and Git Bash
cURL (cmd.exe)	curl.exe command for the Windows Command Prompt, with double quotes and ^ line continuations
JavaScript - Fetch	Fetch API call
JavaScript - Axios	Axios call
Python - Requests	requests call
C# - HttpClient	System.Net.Http.HttpClient call
Go - net/http	net/http program
Java - HttpClient	java.net.http.HttpClient call (Java 11 or later)
PHP - cURL	PHP curl_* functions
Swift - URLSession	URLSession call
Dart - http	package:http call
PowerShell	Invoke-RestMethod call
TypeScript Types	TypeScript interfaces inferred from the request body

The same targets are available from the command line. See CLI code generation.

Request body

Snippets include a body only for POST, PUT, and PATCH requests. When the request has no Content-Type header, Nouto adds one that matches the body type.

Body type	Generated code
JSON	Body text with Content-Type: application/json
Text	Body text with Content-Type: text/plain
XML	Body text with Content-Type: application/xml
URL-encoded	Encoded key=value pairs from the enabled rows
Form data	Multipart form built with the target library, including file fields. cURL sends text fields with --form-string, so a value that starts with @ or < is sent as text.
GraphQL	JSON payload with query, plus variables and operationName when set
Binary	cURL only, as --data-binary @<file>. Other targets omit the body.

Authentication

The snippet carries the request’s auth settings:

Auth type	Generated code
Basic	The library’s basic auth option, or an Authorization: Basic header
Bearer Token	Authorization: Bearer <token> header
API Key	The key as a header or a query parameter, matching the request
OAuth 2.0	Authorization: Bearer header with the request’s current access token, or <access_token> when it has none
Digest, NTLM	Built-in support where the library has it, for example --digest and --ntlm in cURL. Fetch, Axios, Go, Java, and Dart get a comment instead.
AWS Signature v4	--aws-sigv4 in cURL, CURLOPT_AWS_SIGV4 in PHP, and requests_aws4auth in Python. Other targets get a comment with the region and service.

Proxy and SSL settings

When the request has proxy or SSL settings, the snippet includes them where the library supports them. For example, cURL gets --proxy, --insecure, --cert, and --key, and Python gets proxies, verify, and cert arguments. Targets without an equivalent option, such as Fetch and Dart, get a comment that describes the setting.

Example

A POST request with a JSON body and a Bearer token produces this cURL command:

curl \
  -X POST \
  https://api.example.com/data \
  -H 'Authorization: Bearer my-token' \
  -H 'Content-Type: application/json' \
  --data-raw '{"name":"John","age":30}'

Nouto added the Content-Type header because the body type is JSON and the request had no Content-Type header of its own. The body uses --data-raw, so a body that starts with @ is sent as text rather than read from a file.

The cURL (cmd.exe) target produces the same request for the Windows Command Prompt:

curl ^
  -X POST ^
  https://api.example.com/data ^
  -H "Authorization: Bearer my-token" ^
  -H "Content-Type: application/json" ^
  --data-raw "{\"name\":\"John\",\"age\":30}"

A multi-line JSON body is written on one line, because cmd.exe cannot continue a quoted argument on the next line.

TypeScript types

The TypeScript Types target reads JSON from the request body, not from the response. Paste a sample response into the body to generate types for it. Nouto names the root interface after the last non-numeric segment of the URL path, in singular form, so /api/users produces a User interface. When the JSON is an array, Nouto also adds a UserResponse type for the array.
