Developer Guide

Create a new RAPyDo-based project

Start by installing requisites and the rapydo-controller (as for the User guide)

  1. Make sure you meet the pre-requisites on your machine:

    • Python3.5+ (and pip)
    • Git
    • Docker daemon/engine
  2. install the rapydo controller

    Install the latest version: pip3 install --upgrade rapydo-controller

    Your project could require a different version, in this case you will be able to install the right version once configured your project

  3. Create and enter a new directory

  4. Create a new project by using

    rapydo create name --auth YOUR_AUTH_SERVICE --frontend YOUR_FRONTEND

  5. Follow instructions printed by rapydo create output, i.e.
    • git remote add origin https://your_remote_git/your_project.git
    • rapydo init
    • rapydo pull
  6. Now you can edit your projects/$PROJECT_NAME/project_configuration.yaml to customize project title, description, enabled services and so on.

  7. The configuration is now complete, you can start your project by following the User guide or continue to customize by enabling more services or implement endpoints


Enable a service

You can list active services with rapydo list --services

Active services are a combination of services enabled by configuring the ACTIVATE_SERVICENAME variable in projects/$PROJECT_NAME/project_configuration.yaml or .projectrc and services automatically activated due to dependency rules.

By activating a service the backend will establish a connection by using one of the configured extension:

If you want to activate the service but NOT the connection from the backend you can add a SERVICENAME_ENABLE_CONNECTOR=False variable in projects/$PROJECT_NAME/project_configuration.yaml or .projectrc

If you want to activate the connection from the backend but NOT a container for the service, you can configure the SERVICENAME_HOST with an external host.

To summarize:

Service container enabled + Backend connection enable -> ACTIVATE_SERVICENAME

Service container enabled + Backend connection disabled -> ACTIVATE_SERVICENAME && SERVICENAME_ENABLE_CONNECTOR

Service container disabled + Backend connection enable -> SERVICENAME_HOST

Service container disabled + Backend connection disabled -> nothing

Enable Rabbit Management Plugin

Management plugin is disabled by default, you can activate by adding the following variabile to your project_configuration or .proectrc:


You also have to add the following port mapping to your stack configuration (commons.yml to be shared with all stack or into a specific stack configuration):


To enable access to queue you can also add:


Add a new service

RAPyDo is designed to be easily extended with new services in addition to those already provided. For instance, let’s suppose we want to add Apache NiFi. We have to add the new service in {custom}/confs/common.yml and activate it from the {custom}/project_configuration.yml


    image: apache/nifi
      - 8070:8080

and activate it in project_configuration.yml


and rapydo start will do the rest

Backend development


Any service available in RAPyDo as an ORM can be used as authentication for the system, you just need to switch the dedicated variable AUTH_SERVICE. Additionally 2-Factor authentication can be enabled (base on TOTP).

REST classes

RAPyDO is Object Oriented (based to the Flask-Restful plugin): each endpoint is mapped to a class and automatically configured. You can simply create a new python file in projects/YOUR_PROJECT/backend/apis to define your class-endpoint and it will be automatically added to the project.

Base endpoints

Helper endpoints are provided out of the box:

Asynchronous tasks

Celery tasks can be easily activated to be able to launch and control from any endpoint asynchronous tasks. Tasks can be monitored directly from endpoints or from the flower UI. Tasks can save progress, return status, send emails.

Unit tests

py.tests is supported by default. A unit test is a class in a separated tests folder, where you extend the existing base class from where you inherit methods to authenticate and handle tokens.

Frontend framework

Angular is already integrated as base framework for the frontend part. The base authentication (profile, change password, reset password, session lists, JWT tokens) endpoints are already tested inside the base TS code.

In debug mode the framework is served on nodejs/webpack while in production the static dist is built at startup time by the related container entrypoint.

NOTE: we are looking for react to be integrated as well!

Upgrade to a new version

Let’s say your project is based on version A and you want to upgrade it to version B.

  1. edit your project_configuration.yml to change project.rapydo from A to B. Probably you also want to increase your project.version
  2. install rapydo-controller version B (now that you changed the required RAPyDo version in project_configuration.yml you are able to upgrade your controller with rapydo install auto)
  3. if you have custom docker builds change the base image from rapydo/base-image:Ato rapydo/base-image:B
  4. execute the upgrade of your local instance, as describe in User Guide

Your project is now upgraded to version B
