Generate a Bruno API Collection from Your Route Files

Bruno is the open-source, Git-friendly alternative to Postman — collections live as plain files in your repo, not locked in the cloud. Claude can generate a full collection directly from your route definitions.

Here are my Express route files. Generate a Bruno collection with one request per endpoint. Use a {{base_url}} environment variable and include example request bodies for POST and PUT routes.

Claude produces .bru files for each request with the correct method, URL, headers, and body templates. You get a collection you can commit, diff, and code-review alongside the code it documents.

meta {
  name: Create User
  type: http
  seq: 1
}

post {
  url: {{base_url}}/api/users
  body: json
  auth: bearer
}

body:json {
  {
    "name": "Alice",
    "email": "alice@example.com"
  }
}

Once the collection exists, ask Claude to extend it further:

Add a test assertion to every GET request that checks the response status is 200 and the body is valid JSON. Add a pre-request script to the auth endpoints that stores the token in a collection variable.

Bruno's plain-file format means PRs show exactly which requests changed — no more mystery diffs from a binary export.

Your API docs live in Git now — alongside the code they describe.
