ActionServerless - Use GitHub Actions to create a serverless service
ActionServerless is an action to do some computing and then generate a string/JSON file to a path, you can visit the file as a service when in dev/testing, or even in your production. We may take it as a GitHub Actions powered serverless service.
In fact you can do all of these in native GitHub actions. ActionServerless just wraps the steps to simplify the work:
- you can focus on coding the real logic, no need to care too much setup steps on the languages that ActionServerless supported(JS/Ruby/Python/Perl etc.). With a template we provide, you even don't bother to edit the action workflow configuration.
- use the route grammer we defined to specify a path to store the generated string/JSON file, that makes the job easy and clear.
Quick start
At first use the template to create a repository. Then We start with a Python example:
# function.py
import json
# GET /api/py_hello.json
print(json.dumps({"hello": "world"}))
put the file to a path(default is the root path of a repo, otherwise you need add the path as an argument to your actions configuaration), when you push the code the action will be triggered. Then the program's output is written to a file located in api/py_hello.json that you defined as a route in the comment.

HTTP Headers
If we'd like to be serious to take visiting such a GitHub raw file as a 'service', it's no problem for most situations as you request a normal HTTP service. But GitHub returns a text/html for any raw files it serves, that might lead to some bugs though I can't give an example yet.
So we provide a header rewrite service, which returns an application/json header for the json format files(those generated file suffixed with .json), and a text/plain header for the rest(those string or any text-based format files).
Header rewrite usage
Fox example, here's a raw url of the file:
https://raw.githubusercontent.com/gitx-io/ActionServerless/master/README.md
its corresponding header-rewritten url should be:
https://gitx.io/j/gitx-io/ActionServerless/master/README.md
just use gitx.io/j/ to replace the raw.githubusercontent.com/ segment.
