Ruby HTTP client generator for APIs represented with JSON schema.
Add this line to your application's Gemfile:
gem 'heroics'
And then execute:
$ bundle
Or install it yourself as:
$ gem install heroics
Heroics generates an HTTP client from a JSON schema that describes your API. Look at prmd for tooling to help write a JSON schema. When you have a JSON schema prepared you can generate a client for your API:
bin/heroics-generate MyApp schema.json https://api.myapp.com > client.rb
If your client needs to pass custom headers with each request these can be
specified using -H
:
heroics-generate \
-H "Accept: application/vnd.myapp+json; version=3" \
MyApp \
schema.json \
https://api.myapp.com > client.rb
Pass multiple -H
options if you need more than one custom header.
The generated client sends and caches ETags received from the server. By default, this data is cached in memory and is only used during the lifetime of a single instance. You can specify a directory for cache data:
heroics-generate \
-c "~/.heroics/myapp" \
MyApp \
schema.json \
https://api.myapp.com > client.rb
~
will automatically be expanded to the user's home directory. Be sure to
wrap such paths in quotes to avoid the shell expanding it to the directory you
built the client in.
The generated client has Yard-compatible docstrings.
You can generate documentation using yardoc
:
yard doc -m markdown client.rb
This will generate HTML in the docs
directory. Note that Yard creates an
_index.html
page won't be served by Jekyll on GitHub Pages. Add a
.nojekyll
file to your project to prevent GitHub from passing the content
through Jekyll.
The client uses Excon under the hood and raises Excon errors when failures occur.
begin
client.app.create({'name' => 'example'})
rescue Excon::Errors::Forbidden => error
puts error
