Serverless functions and edge microservices made painless

Installation | Getting Started | Documentation | 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.

FLOGO CLI

The Flogo CLI is the primary tool to use when working with a Flogo application. It is used to create, modify and build Flogo applications

Installation

Prerequisites

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

• The Go programming language version 1.11 or later should be installed.
• In order to simplify dependency management, we're using go mod. For more information on go mod, visit the Go Modules Wiki.

Install the cli

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

$ go get -u github.com/project-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
$ git clone https://github.com/project-flogo/cli.git

# Go to the directory
$ cd cli

# Optionally check out the branch you want to use 
$ git checkout test_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": "1.1.0",
  "imports": [
  	"github.com/project-flogo/contrib/trigger/rest",
  	"github.com/project-flogo/flow",
  	"github.com/project-flogo/contrib/activity/log"
  ],
  "triggers": [
    {
      "id": "receive_http_message",
      "ref": "#rest",
      "name": "Receive HTTP Message",
      "description": "Simple REST Trigger",
      "settings": {
        "port": 9233
      },
      "handlers": [
        {
          "settings": {
            "method": "GET",
            "path": "/test"
          },
          "action": {
            "ref": "#flow",
            "settings": {
              "flowURI": "res://flow:sample_flow"
            }
          }
        }
      ]
    }
  ],
  "resources": [
    {
      "id": "flow:sample_flow",
      "data": {
        "name": "SampleFlow",
        "tasks": [
          {
            "id": "log_message",
            "name": "Log Message",
            "description": "Simple Log Activity",
            "activity": {
              "ref": "#log",
              "input": {
                "message": "Simple Log",
                "addDetails": "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

There is documentation also available for CLI Commands and CLI Plugins.
