Serverless functions and edge microservices made painless

Installation | Getting Started | Repos | Contributing | License

Project Flogo is an open source framework to simplify building efficient & modern serverless functions and edge microservices and _this_ is the cli that makes it all happen.

Installation

Prerequisites

To get started with the Project Flogo cli you'll need to have a few things

• The Go programming language version 1.8 or later should be installed.
• The GOPATH environment variable on your system must be set properly
• In order to simplify dependency management, we're using go dep. You can install that by following the instructions here.

Install the cli

To install the cli, simply open a terminal and enter the below command

$ go get -u github.com/TIBCOSoftware/flogo-cli/...

Note that the -u parameter automatically updates the cli if it exists

Build the cli from source

You can build the cli from source code as well, which is convenient if you're developing new features for it! To do that, follow these easy steps

# Get the flogo-cli from GitHub
$ go get github.com/TIBCOSoftware/flogo-cli/...

# Go to the right directory
$ cd $GOPATH/src/github.com/TIBCOSoftware/flogo-cli

# Optionally check out the branch you want to use 
$ git checkout my_branch

# Run the install command
$ go install ./... 

Getting started

Getting started should be easy and fun, and so is getting started with the Flogo cli.

First, create a file called flogo.json and with the below content (which is a simple app with an HTTP trigger)

{
  "name": "SampleApp",
  "type": "flogo:app",
  "version": "0.0.1",
  "appModel": "1.0.0",
  "triggers": [
    {
      "id": "receive_http_message",
      "ref": "github.com/TIBCOSoftware/flogo-contrib/trigger/rest",
      "name": "Receive HTTP Message",
      "description": "Simple REST Trigger",
      "settings": {
        "port": 9233
      },
      "handlers": [
        {
          "action": {
            "ref": "github.com/TIBCOSoftware/flogo-contrib/action/flow",
            "data": {
              "flowURI": "res://flow:sample_flow"
            }
          },
          "settings": {
            "method": "GET",
            "path": "/test"
          }
        }
      ]
    }
  ],
  "resources": [
    {
      "id": "flow:sample_flow",
      "data": {
        "name": "SampleFlow",
        "tasks": [
          {
            "id": "log_2",
            "name": "Log Message",
            "description": "Simple Log Activity",
            "activity": {
              "ref": "github.com/TIBCOSoftware/flogo-contrib/activity/log",
              "input": {
                "message": "Simple Log",
                "flowInfo": "false",
                "addToFlow": "false"
              }
            }
          }
        ]
      }
    }
  ]
}

Based on this file we'll create a new flogo app

$ flogo create -f flogo.json myApp

From the app folder we can build the executable

$ cd myApp
$ flogo build -e

Now that there is an executable we can run it!

$ cd bin
$ ./myApp

The above commands will start the REST server and wait for messages to be sent to http://localhost:9233/test. To send a message you can use your browser, or a new terminal window and run

$ curl http://localhost:9233/test
