Replaces the legacy Nexus module (which proxied custom client builds through a third-party service) with a new custom-client module that triggers a workflow_dispatch on a user-configured generator repository and receives built artifacts via an authenticated callback.
Changes
New custom-client module (src/modules/custom-client/): controller, service, entity, DTOs, and a settings service. Endpoints under /api/custom-client/* cover build submission, listing, deletion, artifact download, a public callback for the workflow, and admin-only settings.
GitHub token / generator repo / ref are stored in system_settings (category custom-client) and managed via API — no env vars. The token is masked in responses, mirroring the SMTP settings pattern.
Callback auth: each build gets a random callbackToken; the workflow POSTs artifacts to /api/custom-client/builds/:uuid/callback with X-Callback-Token. That endpoint is @Public() so it bypasses JWT/RBAC.
Migration1791212800000-ReplaceNexusWithCustomClientBuilds drops nexus_tokens / nexus_builds and creates custom_client_builds. The initial schema snapshot is intentionally left untouched so older deployments can upgrade.
update-check statistics now read from custom_client_builds instead of the Nexus tables.
Nexus module deleted entirely.
Matching generator workflow
The rustdesk-generator side (workflow that this module dispatches) is added in the rustdesk-generator repo on the current branch — only the console side is in this PR.
Verification
npm run build passes
npm run lint passes
jest (46 suites, 553 tests) passes
Known limits
Only windows/x86_64 is wired in the generator workflow; other targets are rejected by a guard job for now.
Custom config injection (app-name, password, disable-* flags) is forwarded as custom-json but not yet applied by the workflow — scheduled for the next iteration.
Summary by CodeRabbit
New Features
Added custom-client build submission for Windows, Linux, macOS, Android, and iOS, with support for building across all platforms.
Added build status and progress tracking, artifact listing and downloads, and build management.
Administrators can configure the build service’s repository, branch, and access token.
Changes
Replaced the previous Nexus build and account-linking experience with custom-client builds.
…lient builder
Drop the Nexus module that proxied custom client builds through a third-party service and introduce a new custom-client module that triggers a workflow_dispatch on a user-configured generator repository. The generator workflow builds the client and POSTs artifacts back to a public callback endpoint authenticated by a per-build token.
GitHub token and generator repo/ref are stored in system_settings and managed via API (no env vars). A migration drops the legacy nexus tables and creates custom_client_builds. update-check statistics now read from custom_client_builds.
Only the console side is covered here; the matching generator workflow lives in rustdesk-generator.

Review comments at @src/modules/custom-client/custom-client.controller.ts:
- Around line 91-94: Configure the FilesInterceptor on the public callback route
with explicit fileSize and files limits so multipart uploads cannot be buffered
without bounds; keep the change scoped to the interceptor used by the
builds/:uuid/callback endpoint.
- Around line 60-89: Update listBuildFiles, downloadBuildFile, and
getBuildProgress to receive the authenticated user ID and pass it to their
service methods; verify build ownership by UUID and userGuid before listing
files, accessing the filesystem, or fetching GitHub run details.
Review comments at @src/modules/custom-client/custom-client.service.ts:
- Around line 200-212: Update listBuildFiles to use statSync(...).isFile() when
filtering entries instead of creating unread, unclosed streams, and replace
createReadStream with statSync in the fs import. Preserve the existing behavior
of excluding entries whose inspection throws.
- Line 197: Update deleteBuild to remove the build’s artifact directory under
custom-client-builds using the existing safeJoin(uuid) path after deleting the
database record; import and use the filesystem removal utility needed for
recursive, forceful cleanup.
- Around line 131-135: Update the GitHub 401/403 handling in the custom-client
response flow to throw a BadGatewayException with the existing message instead
of an UnauthorizedException, so an upstream GitHub error is not returned as a
console-user session failure.
- Around line 229-231: In the callback handler, validate the public status
against the supported build statuses and reject callbacks when build.status is
already completed or failed. Replace the direct callbackToken comparison with
timingSafeEqual using equal-length buffers, and invalidate the token after a
successful callback so it cannot be reused.

@src/modules/custom-client/entities/custom-client-build.entity.ts:
- Around line 35-36: Update the message column in CustomClientBuildEntity to use
the text type, and change the matching message definitions in both SQLite and
MySQL CREATE TABLE statements in the migration to text so long callback messages
can be stored.

…m-build entry
Map os/arch to the matching reusable workflow file (windows-x86_64.yml, linux-aarch64.yml, etc.) and drop the custom-build.yml entry point. Each platform workflow now carries its own workflow_dispatch trigger and notify-console callback job, so the console triggers the target workflow directly.
…rkflow
Allow os='all' to dispatch the aggregated flutter-build workflow that
builds every platform in parallel. arch becomes optional for all-platform
builds and is stored as 'all' in that case.
The mysql-migration.integration.spec.ts maintains its own migrations
array; the new migration was missing from it, causing CI to run only
five migrations instead of six.
Bump the GitHub API version to 2026-03-10 so workflow_dispatch returns
the workflow_run_id directly; store it on the build record. Add a
GET /builds/:uuid/progress endpoint that proxies GitHub's runs/{id}
and runs/{id}/jobs APIs to return the current job/step status.
The routes moved from /api/nexus/* to /api/custom-client/*. The linked databk/rustdesk-console-web repository still calls only the deleted Nexus endpoints. Its custom-client page requires Nexus binding. It also expects the legacy fields appName and cancelled, and a windows-only os. No frontend code calls the new progress or settings endpoints. Ship the matching web change together with this backend change, or the custom-client page stops working.
