ditto

ditto is an HTTP API as a key/value store, useful for testing or prototyping an API that doesn't yet exist.

  • Send a PUT to store some JSON on a path
  • Send a GET to retrieve JSON on a path

Example

(using httpie, but you can send the request any way you like)

$ http PUT https://jkulton--fad998c882d711f092ca0224a6c84d84.web.val.run/books/1 \
  x-api-key:SUPER_SECRET \
  title="The Great Gatsby" \
  cover_image="https://www.gutenberg.org/cache/epub/64317/pg64317.cover.medium.jpg"
HTTP/1.1 200 OK
$ http GET https://jkulton--fad998c882d711f092ca0224a6c84d84.web.val.run/books/1 \
  x-api-key:SUPER_SECRET
HTTP/1.1 200 OK
{
    "cover_image": "https://www.gutenberg.org/cache/epub/64317/pg64317.cover.medium.jpg",
    "title": "The Great Gatsby"
}

Setup

  1. Fork the Val
  2. Create a DITTO_API_KEY env var
  3. Ensure you pass the API key as a x-api-key header with all your requests
  4. Send PUT requests to a path to store data, send GET requests to a path to retrieve data
  5. Have fun!
