ZITADEL TypeScript with Turborepo

This repository contains all TypeScript and JavaScript packages and applications you need to create your own ZITADEL Login UI.

⚠️ This repo and packages are in beta state and subject to change ⚠️

The scope of functionality of this repo and packages is under active development.

The @zitadel/client package is using @connectrpc/connect.

You can read the contribution guide on how to contribute. Questions can be raised in our Discord channel or as a GitHub issue.

Developing Your Own ZITADEL Login UI

We think the easiest path of getting up and running, is the following:

1. Fork and clone this repository
2. Rename the file .github/dependabot.example.yml to .github/dependabot.yml so you don't miss version and security updates.
3. Run the ZITADEL Cloud login UI locally
4. Make changes to the code and see the effects live on your local machine
5. Study the rest of this README.md and get familiar and comfortable with how everything works.
6. Decide on a way of how you want to build and run your login UI. You can reuse ZITADEL Clouds way. But if you need more freedom, you can also import the packages you need into your self built application.

Included Apps And Packages

• login: The login UI used by ZITADEL Cloud, powered by Next.js
• @zitadel/client: shared client utilities for node and browser environments
• @zitadel/proto: Protocol Buffers (proto) definitions used by ZITADEL projects

Each package and app is 100% TypeScript.

Login

The login is currently in a work in progress state. The goal is to implement a login UI, using the session API of ZITADEL, which also implements the OIDC Standard and is ready to use for everyone.

In the first phase we want to have a MVP login ready with the OIDC Standard and a basic feature set. In a second step the features will be extended.

This list should show the current implementation state, and also what is missing. You can already use the current state, and extend it with your needs.

You can find a more detailed documentation of the different pages here.

Custom translations

The new login uses the SettingsApi to load custom translations. Translations can be overriden at both the instance and organization levels. To find the keys more easily, you can inspect the HTML and search for a data-i18n-key attribute, or look at the defaults in /apps/login/locales/[locale].ts.

Tooling

• TypeScript for static type checking
• ESLint for code linting
• Prettier for code formatting

Useful Commands

• make login-quality - Check the quality of your code against a production build without installing any dependencies besides Docker
• pnpm generate - Build proto stubs for the client package
• pnpm dev - Develop all packages and the login app
• pnpm build - Build all packages and the login app
• pnpm clean - Clean up all node_modules and dist folders (runs each package's clean script)

Learn more about developing the login UI in the contribution guide.

Versioning And Publishing Packages

Package publishing has been configured using Changesets. Here is their documentation for more information about the workflow.

The GitHub Action needs an NPM_TOKEN and GITHUB_TOKEN in the repository settings. The Changesets bot should also be installed on the GitHub repository.

Read the changesets documentation for more information about this automation

Run Login UI

To run the application make sure to install the dependencies with

pnpm install

then generate the GRPC stubs with

pnpm generate

To run the application against a local ZITADEL instance, run the following command:

pnpm run-zitadel

This sets up ZITADEL using docker compose and writes the configuration to the file apps/login/.env.local.

Alternatively, use another environment

You can develop against any ZITADEL instance in which you have sufficient rights to execute the following steps. Just create or overwrite the file `apps/login/.env.local` yourself. Add your instances base URL to the file at the key `ZITADEL_API_URL`. Go to your instance and create a service user for the login application. The login application creates users on your primary organization and reads policy data. For the sake of simplicity, just make the service user an instance member with the role `IAM_OWNER`. Create a PAT and copy it to the file `apps/login/.env.local` using the key `ZITADEL_SERVICE_USER_TOKEN`.

The file should look similar to this:

ZITADEL_API_URL=https://zitadel-tlx3du.us1.zitadel.cloud
ZITADEL_SERVICE_USER_TOKEN=1S6w48thfWFI2klgfwkCnhXJLf9FQ457E-_3H74ePQxfO3Af0Tm4V5Xi-ji7urIl_xbn-Rk

Start the login application in dev mode:

pnpm dev

Open the login application with your favorite browser at localhost:3000. Change the source code and see the changes live in your browser.

Make sure the application still behaves as expected by running all tests

pnpm test

To satisfy your unique workflow requirements, check out the package.json in the root directory for more detailed scripts.

Run Login UI Acceptance tests

To run the acceptance tests you need a running ZITADEL environment and a component which receives HTTP requests for the emails and sms's. This component should also be able to return the content of these notifications, as the codes and links are used in the login flows. There is a basic implementation in Golang available under the sink package.

To setup ZITADEL with the additional Sink container for handling the notifications:

pnpm run-sink

Then you can start the acceptance tests with:

pnpm test:acceptance

Deploy to Vercel

To deploy your own version on Vercel, navigate to your instance and create a service user. Then create a personal access token (PAT), copy and set it as ZITADEL_SERVICE_USER_TOKEN, then navigate to your instance settings and make sure it gets IAM_OWNER permissions. Finally set your instance url as ZITADEL_API_URL. Make sure to set it without trailing slash.
