Serverless Platform for Ruby and Crystal

Let's.

faastruby new-project hello --api + d ./hello + f ./hello/project.yml + f ./hello/secrets.yml + d ./hello/functions/root + f ./hello/functions/root/handler.rb + f ./hello/functions/root/faastruby.yml + d ./hello/functions/catch-all + f ./hello/functions/catch-all/handler.rb + f ./hello/functions/catch-all/faastruby.yml + d ./hello/public + f ./hello/public/faastruby.yml + f ./hello/.gitignore Initialized empty Git repository in ～/hello/.git/ Project 'hello' initialized. Now run: $ cd hello $ faastruby local Then visit http://localhost:3000

mkdir functions/rb

faastruby.yml --- cli_version: 0.5.25 name: rb runtime: ruby:2.6

handler.rb def handler event response = { 'hello' => 'world' } render json: response end

mkdir functions/cr

faastruby.yml --- cli_version: 0.5.25 name: cr runtime: crystal:0.27.2

handler.cr require "json" def handler(event) response = JSON.build do |json| json.object do json.field "hello", "world" end end render json: response end

faastruby deploy ┌ Deploying project 'hello' to workspace 'hello-stage- ～' ├── [✔] Connecting to workspace 'hello-stage- ～' ├── [✔] Uploading static assets in 'public' ├── [✔] Deploying function from 'functions/rb' ├── [✔] Deploying function from 'functions/cr' ├── [✔] Deploying function from 'functions/catch-all' └── [✔] Deploying function from 'functions/root' * Project URL: https://hello-stage- ～. ～.faast.cloud

$ curl 'https://hello-stage- ～. ～.faast.cloud/rb' {"hello":"world"} $ curl 'https://hello-stage- ～. ～.faast.cloud/cr' {"hello":"world"}

Works! faast faast
