Seed and Genx

A seed is a user-friendly, buildable template by Genesis for generating an application/platform project. It can be an approved baseline for multiple applications with, of course, different owners and parameters and not just one.

It is important to note that a seed acts like a standard baseline; even though it can be modified by seed owners, it should not be. However, developers and testers are free to experiment on the applications that they build on a seed.

Correlation between a seed and Genx

Genx is a Genesis command-line utility that enables you to access a parameterised seed and generate a new project from it.

This blank-app-seed is called the Quick Start Application; it is used to create a basic Genesis project.

When you create an application with Genx, you will see seed listings in different versions. There are only two seed versions approved by Genesis:

  • Seed A
  • Seed A (Next/Pre-Release)

When presented, these choices enable you to build on the official Seed A baseline, which is stable and provides early access to what is being prepared. The Seed A (Next/Pre-Release) version of the official seed A is for experiment or testing only.

You should ignore any other seed version listings.

Main differences between the two seed versions

Seed ASeed A (Next/Pre-Release)
Official seed for the actual application developmentFor test/experimentation purpose
Ongoing support, upstream fixes and upgrades availableNo support available

Some important points to note about seeds used by Genx:

  • Any local directory/project can become a seed by adding a root level .genx directory (CLI API)
  • Developers may clone an existing seed to form a new one
  • Developers contribute to official seeds by cloning that seed repo
  • Select code owners manage merges
  • Available to all Genesis users


  • Recommended Operating system : Windows 10 Pro
  • Node.js version 20

Launching genx

Open a terminal on your machine and launch the CLI tool using this:

npx -y @genesislcap/genx@latest init myApp

This command presents you with a sequence of choices for creating and configuring applications.

Using genx

First, you'll be prompted the following messages:

 ℹ Downloading genesiscommunitysuccess seed blank-app-seed (Git ref main) to myApp directory...
✔ Seed downloaded in 1554ms
ℹ Installing seed NPM dependencies...
✔ Installed

Thanks for choosing this seed:
Name: @genesiscommunitysuccess/blank-app-seed
Description: Genesis Blank App Seed
Version: 1.0.0
License: Apache-2.0

You can override the default Genesis server URL used during local development.

Next, you will be asked to set an API host. The default is Yes.

? Set API Host (Yes/no)

If you choose Yes, then you need to provide an API Host. Default is (ws://localhost/gwf/):

? API Host (with WebSocket prefix and suffix if any)

After that it will ask if there is any SSO connection. Default is (No):

? Init SSO connection before loading application

The next prompts concern the back-end part of the application.

The first prompt is for the group id:

? Group Id global.genesis

... and this is followed by the application version:

? Application Version 1.0.0-SNAPSHOT

Press Enter and you should be greeted by a message saying that the application was created successfully.

Open the project in IntelliJ to start building. But note - it takes a few minutes to set up the folder structure, so be patient.

Here's a quick overview of the generated application's folder structure:

Above, we have expanded the client folder. This contains all the UI-related projects.

The server folder follows the same structure. This contains all the server-side projects.


Workspaces are top-level client monorepos that contain various packages, such as components, micro front-ends, design systems, and at least one application. All these packages can be versioned and released independently. This set-up provides an enhanced developer experience.

The workspace generator automates the following steps for you:

  • It creates a local workspace from a local or remote seed and configures it.
  • It persists the information captured during your CLI session within the workspace filesystem for future use.

Workspaces and application filesystem

Your apps are local to workspaces; they don't exist in isolation.

After you have created a workspace, your workspace filesystem should look something like this (depending on the seed).

├── apps
│ ├── demo
├── components
├── design-systems
│ └── alpha
├── micro-frontends
├── services
└── utils

This is a monorepo containing multiple packages. Each package can be released independently.
