Getting Started with ADK

The App Developer Kit (ADK) is the preferred tooling for web developers to get started building extension apps on Symphony

Generate your Extension App

The Symphony Generator offers a fast way to bootstrap your Symphony extension app project.
Prerequisite: Install NodeJS first, either directly or via nvm. You can also use other package managers like bun or yarn, which the generator will attempt to use before falling back to npm.
First, install yeoman and the Symphony Generator.
npm
yarn
bun
$ npm i -g yo @finos/generator-symphony
$ yarn global add yo @finos/generator-symphony
$ bun add -g yo @finos/generator-symphony
Then, create a directory for your new app project and launch the generator.
$ mkdir my-app && cd $_
$ yo @finos/symphony
This will prompt you with a number of questions about your app and pod configuration. Type in your app ID, using arrow keys to scroll and press enter to move on to the next prompt.
When prompted for Select your type of application, choose Extension App (ADK). You then have a choice of different project types:
  • Basic - simple project to demonstrate initialization
  • App View - uses React with either JavaScript or TypeScript to create app views
  • Message Renderer - overrides rendering of messages with custom formatting
If you require an extension app that requires user identity, you will also need a backend that can perform the Circle of Trust process. You should then select the Extension App + Circle of Trust (ADK + BDK) option, which will generate both the extension app project using ADK and a backend project using BDK that will perform the app authentication and validation.

To launch your project, first run: bun start
Then, visit https://localhost:4000/controller.html and dismiss the warning
Finally, visit https://develop2.symphony.com/?bundle=https://localhost:4000/bundle.json

Create Application

When you are ready to deploy your app permanently (or if you require Circle of Trust), follow the instructions on this page to setup your app.

Start your App

$ npm start # or yarn start or bun start
$ webpack-dev-server --mode=development
SYMPHONY ADK 1.3.0
Building application: my-app
Running at: /Users/user/code/my-app

Test your App

  1. 1.
    A browser window should launch with the URL https://localhost:4000/controller.html. If it doesn't, visit that page manually. Dismiss the security warning and close the page.
  2. 2.
    Visit https://develop2.symphony.com/?bundle=https://localhost:4000/bundle.json to inject the running app temporarily into a pod for testing
  3. 3.
    Acknowledge the developer mode notice. Your app is now loaded.

Next Steps

Each project type in the generator corresponds to one of the guides below. Read the respective guide for explanations of how to use ADK.
