Crystal OpenFaaS Template
Inofficial OpenFaaS template for the crystal programming language (currently 0.35.1).
To find out more about the OpenFaaS templates see the faas templates and faas-cli.
Usage
Go to your openFaaS project and execute:
faas-cli template pull https://github.com/TPei/crystal_faas_template
Alternatively, the template is also available via the OpenFaaS template store
faas-cli template store pull crystal
This will pull the template into your directory and allow you to use
faas-cli new --lang crystal my_function
to create a new crystal function
See crystal_faas_whalesay_demo for an implementation example.
Development
General
As with all OpenFaaS templates, this template creates a my_function/handler.cr file, as well as a my_function.yml. In addition to this, a my_function/shard.yml is created for your dependencies.
When building your function with faas-cli build -f my_function.yml your dependencies will be resolved according to your shard file.
Code
Hander#run gets passed a req String, if you want to handle json, simply do JSON.parse(req) and do your thing :)
Your function always needs to return JSON, like so: return JSON::Any.new("Just a String, but JSON!")
require "json"
class Handler
def run(req : String)
whale = <<-WHALE
#{"-" * req.size}
< #{req} >
#{"-" * req.size}
