This is a very basic script that renders the YAML file (in the OpenAPI 3.0 spec) that is used as the source for Firefly III's API documentation. I wrote it because the API YAML file was well over 1400 lines before I got sick of editing such a large file. The current stitched result is well over 7500 lines at the time of writing.

What it does is simply join all YAML files in /yaml/ together, preceded by the start.yaml.twig file in the /templates/ directory.

1. Rename .env.example to .env and adjust the variables accordingly, e.g.

   API_VERSION=0.10.0
   API_DESTINATION=./
   API_ROOT=./

2. Install dependencies via Composer

   $ composer install

3. Install PHP yaml.so extension. It should be added to your php.ini automatically.

   $ pecl install yaml

4. Generate firefly-iii-${API_VERSION}.yaml file

   $ php index.php

The resulting firefly-iii-${API_VERSION}.yaml file can be imported into your favorite API development environment to play around with, e.g. Postman.

I'm actively writing all API documentation, so the file may change.

Feel free to create a PR on anything. If you want to change endpoints, check out /yaml/paths. Or edit objects in /yaml/schemas. This is my first API document so feel free to tell me how to improve.

You can see the result on this page.
