Automatically generated PR resolving Knowledge Gap ID 65. **Thread ID:** manual-1787771291264 **Action:** CREATE **New File:** `apps/docs/content/guides/integrate/login-ui/fork-and-deploy-login-app.mdx` ### AI Summary > My recommendation is to publish a a new Deploy & Operate guide for the Login App, then link to it from the existing Login App page. The existing pages address architecture/development, login-client authorization, and Login V2 adoption separately, but none currently explains long-term fork ownership and upgrades. (Contribution guide, login-client setup, adoption guide) The article should cover: Full-repository fork as the simplest current recommendation. The customer’s history-preserving slim-fork approach as an advanced alternative. Why copying only apps/login is unsafe while the current npm packages remain unavailable, linked to #12250. Release-tag pinning and versioning such as v4.17.0-custom.1. Development, generation, linting, tests, and Docker builds. An EKS/Kubernetes Deployment and Service example. PAT handling through ZITADEL_SERVICE_USER_TOKEN_FILE. Same-origin versus separate-domain proxy requirements. Gradual rollout, break-glass access, rollback, and troubleshooting. A repeatable upstream synchronization and release process. ### Human Reviewer Instructions > Sample content: > Maintain and deploy a customized ZITADEL Login UI > > The ZITADEL Login UI is an MIT-licensed Next.js application maintained in the ZITADEL monorepo. You can customize and deploy it independently, but your fork becomes an application that your team must build, test, secure, monitor, and update. > > This guide describes the current workflow for maintaining a customized Login UI. It is intended for teams that need source-code changes beyond the branding and text customization available through ZITADEL settings. > > If you only need to change colors, logos, fonts, or translated login text, first use ZITADEL's supported branding and customization settings. A source fork creates an ongoing maintenance responsibility. > > Understand the source dependencies > > The Login UI is not currently an isolated project in the repository. Its relevant dependency chain is: > > apps/login > └── packages/zitadel-client > └── packages/zitadel-proto > └── proto > > The root pnpm workspace and Nx configuration also participate in installing, generating, testing, and building these projects. Copying only apps/login can therefore fail or silently separate the UI from the API definitions against which it was developed. > > For the current monorepo workflow, keep the Login UI and these workspace dependencies on the same upstream ZITADEL revision. > > Choose a fork strategy > > Full repository fork — recommended > > Fork the complete zitadel/zitadel repository and limit your own changes to apps/login wherever possible. This is the simplest model to understand and the least likely to miss a new build-time dependency when upstream changes. > > Use two remotes: > > git clone [email protected]:YOUR_ORGANIZATION/zitadel.git > cd zitadel > git remote add upstream https://github.com/zitadel/zitadel.git > git fetch upstream --tags > > Start customization from a released tag rather than an arbitrary commit on main: > > git checkout -b custom-login/vX.Y.Z vX.Y.Z > > Replace vX.Y.Z with the ZITADEL release you have selected. A release tag gives you a reproducible compatibility baseline and a corresponding changelog. > > History-preserving slim fork — advanced > > If repository size or internal policy makes a full fork impractical, you can maintain a filtered fork containing only: > > apps/login > > packages/zitadel-client > > packages/zitadel-proto > > proto > > the root pnpm, lockfile, Node, and Nx configuration required by those projects > > Use git filter-repo identically both when bootstrapping the fork and during every later synchronization. The list of retained paths and all filter arguments must remain stable so that freshly filtered upstream history shares commit ancestry with your fork. > > Important constraints for this model: > > Bootstrap and update with one shared filtering implementation; do not duplicate the path list in separate scripts. > > Merge the initial import and subsequent update branches with a merge commit or fast-forward. Do not squash them, because squashing removes the filtered upstream ancestry needed for future three-way merges. > > Treat any change to the retained path list as a new bootstrap. Adding or removing paths rewrites the filtered commit IDs. > > Re-run pnpm install after filtering or merging so the lockfile is reconciled with the retained workspace. > > Review the retained path list whenever upstream changes the Login build graph. > > This is a valid Git maintenance technique, but it adds machinery that ZITADEL's normal build does not require. Own and test the filtering automation as part of your fork. > > Why a standalone apps/login copy is not recommended today > > At the time of writing, current @zitadel/client and @zitadel/proto releases are not available as version-matched npm dependencies for the Login UI. The application consumes their workspace sources from the monorepo. Until version-matched packages are published, retain those sources rather than replacing the workspace dependencies with old npm versions. Progress is tracked in zitadel/zitadel#12250. > > Configure a development environment > > The current contribution guide requires Node.js 22.x, Corepack/pnpm, and Nx. From the repository root: > > corepack enable > pnpm install > pnpm nx run-many --target generate > > To develop the Login UI against an existing ZITADEL instance, create apps/login/.env.dev.local: > > ZITADEL_API_URL=https://your-zitadel-instance.example.com > ZITADEL_SERVICE_USER_TOKEN=your-login-client-pat > > Do not commit this file or its token. ZITADEL_API_URL must not have a trailing slash. > > Start the development server: > > pnpm nx run @zitadel/login:dev > > The token must belong to a machine user with the Instance Login Client role (IAM_LOGIN_CLIENT). See Connect your self-hosted Login UI to ZITADEL for the supported setup. > > Run the required quality checks > > Run the checks for all three affected projects, not only the Next.js application: > > pnpm nx run-many \ > --projects @zitadel/login @zitadel/client @zitadel/proto \ > --targets lint build test > > If your update includes .proto changes, regenerate the TypeScript clients before testing: > > pnpm nx run @zitadel/proto:generate > > For meaningful Login UI changes, also perform end-to-end tests against a staging ZITADEL instance. At minimum, cover the authentication methods and policies you enable in production: > > Authorization Code Flow with PKCE and callback to the application > > password, passkey, external identity provider, and applicable MFA/OTP flows > > registration, account selection, password reset, verification, and logout > > organization-specific policies, branding, and translated text > > expected negative cases such as invalid or expired codes > > desktop and mobile browsers supported by your application > > Build an immutable image > > The repository's documented Docker build flow is: > > pnpm nx run @zitadel/login:build > docker build -t registry.example.com/identity/zitadel-login:vX.Y.Z-custom.1 apps/login > docker push registry.example.com/identity/zitadel-login:vX.Y.Z-custom.1 > > Use an immutable tag that records both the upstream ZITADEL baseline and your customization revision. For example: > > v4.17.0-custom.1 > > Also retain the source commit and image digest in your release record. Do not deploy a mutable latest tag to production. > > Deploy outside Vercel > > Vercel is not required. The Login UI can run as the Node.js application produced by the Next.js build or as a container. In Kubernetes or EKS, run it as a separate Deployment and Service behind your ingress or load balancer. > > The following fragment shows the important application settings.
