UiPath Coded Apps
Build, debug, and deploy UiPath Coded Web Applications and Coded Action Apps using the uip codedapp CLI and @uipath/uipath-typescript SDK.
When to Use This Skill
- User wants to build, debug, or deploy a UiPath Coded Web App or Coded Action App
- User asks about
uip codedapp commands, .uipath/ directory, app.config.json, or action-schema.json
- User wants to scaffold a new React/Vue frontend for UiPath Cloud or an Action Center form
- User asks for app UI that a prebuilt UiPath widget covers: review/correct Document Understanding extraction results (Validation Station), chat with a conversational agent, browse/edit a Data Fabric entity in a grid, upload files to a storage bucket, display a PDF, or sign in with an external IdP (Google/SAML)
- User wants to push/pull source between local and Studio Web
- User wants to use the
@uipath/uipath-typescript SDK from a coded app
- User wants to run the full pipeline (build → pack → publish → deploy)
- User wants to generate an agent-monitoring / analytics dashboard from a natural-language description — e.g. "show agent health, error rates, invocation volume, latency, active agents, KPIs, governance metrics, or consumption trends"
- User says "build/create/generate a dashboard", describes metrics to visualize, or asks for an agent observability, operations, or cost view
App Types
| Type | Description | Key Difference |
|---|
| Coded Web App | React/Vue/other frontend hosted on UiPath CDN | User-facing app accessed via a URL |
| Coded Action App | React form wired to UiPath Action Center | Rendered inside human task reviews in Maestro/Agent workflows |
Two lifecycles, two scaffolding entry points.
- Standalone coded app: scaffold with
npx create-vite@latest (see create-web-app.md / create-action-app.md). No project.uiproj / webAppManifest.json — those are solution-membership artefacts and standalone apps don't need them. Deploy via uip codedapp pack → uip codedapp publish (-t Action for action apps) → uip codedapp deploy. This is the classic single-app lifecycle covered by the rest of this skill.
- In-solution coded app: run
uip codedapp init from inside a .uipx solution. Init writes project.uiproj (ProjectType: "AppV2") + webAppManifest.json, nests runtime + build artefacts under source/dist/, auto-registers the project as Type: "AppV2" in the .uipx, and emits resources/solution_folder/app/{Coded,CodedAction}/. From then on the app is part of the solution — uip solution pack bundles its .nupkg and uip solution deploy run provisions it in the deployment folder. Do not run uip codedapp pack / publish / deploy on a coded app that's already registered in .uipx — that bypasses the solution's deploy config (external client ID, routing name, action schema) and double-registers the package. uip solution projects add / uip solution projects import register existing AppV2 folders too, reading webAppManifest.config.isActionApp to pick the Coded / CodedAction subType. For the solution-side lifecycle see /uipath:uipath-solution.
uip codedapp init is for solutions only. It is not the scaffolding entry point for a standalone coded app — use create-vite for that.
Critical Rules
- Identify the app type before doing anything else. Ask as a structured choice (Rule 18): Coded Web App — custom frontend deployed to UiPath Cloud · Coded Action App — form for Action Center human task reviews. The two paths diverge on scaffolding, redirect URI, and publish flag — do not guess.
- Always check login status first. Run
uip login status --output json before any cloud command. If not logged in, run uip login.
- Never skip the build step. Run
npm run build after scaffolding (to verify the scaffold compiles) and again before pack or push (to produce the deployable dist/). Verify dist/ exists each time.
- Pack → Publish → Deploy order is required. Each step depends on the previous one producing its output.
- Bump the version for re-publish. If the same version already exists in Orchestrator, publish will fail.
- Action apps require
-t Action on publish. Run uip codedapp publish -t Action (not the default Web type).
- Never handle access tokens manually. Do not pass, print, parse, source, or set cached access tokens. Use
uip login and supported uip codedapp commands; the CLI manages authentication.
- Base URL must use the API subdomain.
https://api.uipath.com not https://cloud.uipath.com. See the table below.
vite.config.ts must always set base: './'. The platform handles URL routing — apps must use relative asset paths. Do not use a routing name or a sub-path here. Import static assets through the bundler (import logo from './assets/logo.png') so Vite fingerprints and base-rewrites them. Do NOT place them in public/ or reference them by a hardcoded /-rooted path — those bypass base rewriting and 404 after deploy under the non-root mount.
- Use
getAppBase() from @uipath/uipath-typescript for any absolute URL constructed at runtime — router basename, image src, fetch paths. Deployed apps mount at a non-root prefix; /-rooted paths work locally but 404 after deploy. Vite's base: './' only fixes import-time references.
uip codedapp deploy must run non-interactively. Pass the folder key as --folder-key <GUID> (or as UIPATH_FOLDER_KEY=<GUID> env-var prefix — either works). The interactive folder picker fails in non-TTY contexts (CI, agent shells). If the user provides a folder name, resolve it with the server-side filter uip or folders list --all --name "<name>" --output json and pick the row whose Name exactly equals the target, then read its Key (the plain list is paginated 50/page and --name is a contains match requiring --all, so never just take the first row). A personal workspace is not in --all — resolve it from the default uip or folders list --output json where Type == "Personal". To deploy into a new folder, create it first with uip or folders create "<NAME>" --output json and read Data.Key. The uip or ... commands require the Orchestrator tool — install once via uip tools install @uipath/orchestrator-tool (check first with uip tools list).
- Guard against text overflow in every UI. See patterns.md "Preventing Text Overflow".
- Inspect the DF schema before writing analytics, filters, or seeds. Run
uip df entities get <ENTITY_ID> --output json to inspect fields and types. At runtime, use entities.getById(<id>) from the app's authenticated session. DF doesn't behave like a typical RDBMS; see sdk/data-fabric.md "Anti-shapes & gotchas".
- Every list call returns ONE page — even with no options. There is no "give me everything" path. Applies to
getAll, getAllRecords, queryRecordsById, getFileMetaData, etc. getAll() with no options does NOT return all rows; the SDK sends no pageSize and the server applies its own cap, wrapped in a misleadingly-named NonPaginatedResponse. To list every row from a source that may exceed the cap, you MUST loop the cursor: while (page.hasNextPage) { page = await getAll({ cursor: page.nextCursor }) } and accumulate items. Reading result.items.length after a single call is almost always a bug. See sdk/pagination.md.
- Tables of dynamic data must paginate, not dump all rows in one scroll. Page size 25–50 with next/prev/page-number controls and a "Showing X–Y of Z" summary. Top-N + "see all" is acceptable for explicitly summary panels (e.g., "Top 10 oldest"). Infinite-scroll-of-N-rows is unusable for operational dashboards. Applies to any table backed by any service (DF entities, Tasks, Jobs, Conversations, Process Instances, etc.). See patterns.md "Tabular Data".
- When adding any new SDK method call, verify the configured OAuth scope already includes the required scope — both dashboards and web apps read the
scope key from uipath.json. Write operations, action methods (Jobs.stop, Tasks.complete, ProcessInstances.cancel, etc.), or first use of a new service typically need broader scopes than read-only flows. Mismatched scopes fail silently with 401 / 403 on the first call. See oauth-scopes.md for scope bundles and the per-method lookup protocol (the per-method table ships inside the SDK package at node_modules/@uipath/uipath-typescript/docs/oauth-scopes.md).
- Never call
sdk.initialize() in an action app. That is web-app-only — it starts a PKCE OAuth redirect. Action apps run in Action Center's iframe with a host-injected session: construct new UiPath() (no args) and use it directly. See create-action-app.md src/uipath.ts.
- Never make the user type magic phrases. Whenever you ask the user to pick between known options (app type, build/edit/deploy intent, OAuth setup, deploy pinning), present a structured choice via the host coding agent's native question tool (selectable options) when one exists. Mechanics: one option per choice with a short bold label + one-line description of what picking it does; put the recommended option first and suffix its label "(Recommended)"; keep to at most 4 options (reserve one slot for an escape option like Make changes / Cancel when applicable). If there are 5+ candidates, or the host agent has no question tool, render a plain numbered list instead and accept the number or the option label as the answer. A free-text reply must always remain valid (e.g. a plan-change request) and takes precedence over the options. Exception — never put a question in the same response as a long output: plan-approval gates are free-text by design (the plan ends with "confirm or tell me what to change"); structured questions fire only on later, short turns. See
references/dashboards/plugins/build/impl.md.
- Never guess SDK method signatures — read the installed types. The authoritative reference for method names, parameters, return types, and usage examples is
node_modules/@uipath/uipath-typescript/dist/<subpath>/index.d.ts (full JSDoc; matches the installed SDK version exactly). Before calling a service you have not used in this session, Read its .d.ts. If node_modules is absent, run the install step first — the app cannot build without it. The references/sdk/*.md files deliberately do NOT list signatures; they cover only scopes, calling conventions, and traps the types cannot express. See references/sdk/imports.md for the missing-capability protocol. Boundary: read the .d.ts, never the compiled bundle. dist/*.mjs / *.js is minified implementation, not API — reading it dead-ends. A grep with no output confirms absence; treat a genuine gap as unsupported (use the documented alternative) rather than escalating the search into the bundle.
Disambiguation — Apps vs Dashboards
Route directly to Apps workflow (sections below) when you see:
web app, action app, codedapp, app.config.json, action-schema.json,
scaffold app, deploy app, pack, publish, push, pull, debug app
Route directly to references/dashboards/CAPABILITY.md when you see:
dashboard, analytics, KPI, metrics, Insights, observability,
admin console, report, chart, trend, governance report, agent metrics
When intent is ambiguous — ask "Which fits your goal?" as a structured choice (Rule 18):
| Option | Description |
|---|
| Build or modify a Web App / Action App | Scaffold a UI, form, or app that deploys to Automation Cloud |
| Generate a dashboard | Analytics or admin view from a natural-language description |

CLI Setup
# Install the UiPath CLI (run once)
npm install -g @uipath/cli
# Install the coded apps tool
uip tools install @uipath/codedapp-tool
# Install the Orchestrator tool (needed to resolve folder name → key for deploy)
uip tools install @uipath/orchestrator-tool
# Verify both are installed
uip tools list
# Resolve uip if not on PATH
UIP=$(command -v uip 2>/dev/null || npm root -g 2>/dev/null | sed 's|/node_modules$||')/bin/uip
$UIP --version
Authenticate before any cloud command:
uip login status --output json # check if logged in
uip login # interactive OAuth (opens browser)
uip login --authority https://alpha.uipath.com # non-production environments
# Client-credentials (headless/CI) — scope MUST name one Orchestrator scope AND
# the two Apps-service scopes. Neither set covers the other:
# OR.Default → Orchestrator
# Apps.Read Apps.Write → Apps-service registration in `uip codedapp publish`
# Do NOT substitute granular Orchestrator scopes (OR.Folders/OR.Execution/
# OR.Administration) for OR.Default.
uip login \
--client-id <id> \
--client-secret <secret> \
--organization <org> \
--tenant <tenant> \
--scope "OR.Default Apps.Read Apps.Write" \
--authority https://alpha.uipath.com # omit --authority for production
The uip login session scope is separate from the app's runtime OAuth scopes. The scopes in uipath.json are what the deployed app requests at runtime (see oauth-scopes.md). The --scope on uip login above is what the CLI session needs to call the Apps registration API during uip codedapp publish. uip codedapp publish does two things: uploads the package (needs OR.Default) and registers the coded app (needs Apps.Read Apps.Write). For what each failure looks like, see debug.md.
SDK Config (web app)
The web app initializes the SDK with new UiPath() (no config). At runtime the SDK reads clientId, scope, orgName, tenantName, baseUrl, and redirectUri from <meta name="uipath:*"> tags. During local dev @uipath/coded-apps-dev injects those tags from uipath.json (committed) — the single config source, holding clientId, scope, orgName, tenantName, baseUrl, and redirectUri (the Vite dev URL for local). In production the UiPath platform injects the same tags directly.
To change any of these values, edit uipath.json.
CLI Environment Variables
| Variable | Used By | Description |
|---|
UIPATH_PROJECT_ID | uip codedapp push / uip codedapp pull | Studio Web project ID |
Base URL by environment:
| Environment | Correct Base URL |
|---|
| Production (cloud) | https://api.uipath.com |
| Staging | https://staging.api.uipath.com |
| Alpha | https://alpha.api.uipath.com |
Quick Deploy (Full Pipeline)
Do NOT pause between steps to ask "should I continue?" — execute the full pipeline. Only stop if you need auth credentials or an app name.
- Auth —
uip login status --output json. If not logged in, ask the user for their environment and run uip login. With client credentials (headless/CI), use --scope "OR.Default Apps.Read Apps.Write" — all three names are required: OR.Default for Orchestrator, Apps.Read and Apps.Write for the Apps-service registration in uip codedapp publish. The External Application itself needs only Apps.Read and Apps.Write; OR.Default is auto-granted and not portal-selectable, so name it in --scope. If publish or deploy then fails, see debug.md.
- Build —
npm run build. Verify ls dist/.
- Pack —
uip codedapp pack dist -n <name> --version <version>. Produces .uipath/<name>.<version>.nupkg. Bump version if previously published.
- Publish —
uip codedapp publish (add -t Action for action apps). Verify cat .uipath/app.config.json.
- Deploy —
uip codedapp deploy -n <name> --folder-key <GUID>. Resolve the GUID from the chosen folder: a personal workspace (Type == "Personal"), a named existing folder, or a freshly uip or folders created one — via uip or folders list --output json. Dashboards additionally choose a deploy mode (standalone / governance-pinned / governance) that sets --tags; see dashboards deploy impl. Never let the command go interactive. Share the app URL with the user.
SDK Module Imports
See references/sdk/imports.md for the lookup protocol (subpaths and classes are discovered from the installed package — ls node_modules/@uipath/uipath-typescript/dist/), type import conventions, and anti-pattern examples. Core rules are listed under Anti-patterns below.
Key Concepts
App Config (.uipath/app.config.json)
Created by publish, consumed by deploy. Contains appName, systemName, appType, deploymentId, appUrl. Do not delete .uipath/ between publish and deploy.
Action Schema (action-schema.json)
Action apps define a data contract between the form and the Maestro/Agent workflow. It has four sections: inputs (read-only data from automation), outputs (user-filled fields), inOuts (pre-populated but editable), and outcomes (submission buttons like Approve/Reject).
Troubleshooting
See references/debug.md for detailed diagnosis steps.
| Error | Cause | Fix |
|---|
Not authenticated | No valid session | Run uip login |
dist/ not found | App not built | Run npm run build |
Published app with package name '<name>' and version '<version>' already exists | Same name+version already published (registration rejects duplicates) | Bump --version and re-publish |
Folder key required / deploy hangs on prompt | Missing folder for CLI deploy | Resolve folder name → key via uip or folders list --output json (match on Name, read Key), then run uip codedapp deploy --folder-key <GUID> .... See pack-publish-deploy.md. |
No packages found | No .nupkg in .uipath/ | Run pack first |
| Login fails / redirect error | OAuth misconfiguration | See debug.md |
| API calls fail with 401/CORS | Wrong base URL | Use https://api.uipath.com not cloud.uipath.com |
Folder identifier names differ across CLI and SDK. The CLI uses UIPATH_FOLDER_KEY / --folder-key (string) and applies only to uip codedapp deploy. SDK methods use different parameters: Maestro services (MaestroProcesses, ProcessInstances, Cases) take folderKey (string GUID), Orchestrator services (Assets, Queues, Buckets, Processes) take folderId (number). Do not pass the CLI env var into SDK calls. To bridge from a Maestro folderKey to an Orchestrator folderId, see sdk/maestro.md — and never parseInt(folderKey), the GUID is not numeric.
Completion Output
When you finish a task, report only what's applicable to the work actually done:
- What was done — files created, edited, or deleted (list paths); CLI commands run
- Stage reached — one of: scaffolded / built / packed / published / deployed
- Artifacts produced (report only the ones that actually exist):
dist/ — if npm run build was run
.uipath/<name>.<version>.nupkg — if pack was run
.uipath/app.config.json with deploymentId — if publish was run
- Live deployment URL (
appUrl from app.config.json) — if deploy was run
- External Application client ID — if one was created this session
- Next steps, depending on where the task stopped:
- Scaffolded only:
cd <app-name> && npm run dev to run locally
- Built but not packed: ready to
uip codedapp pack when the user wants to deploy
- Published but not deployed: run
uip codedapp deploy to go live
- Deployed (Web): open/share the deployment URL; verify sign-in flow
- Deployed (Action): the app will render in Action Center human tasks triggered by Maestro/Agent workflows matching the routing name
- Open issues — any auth failures, scope mismatches, missing folder key, skipped steps, or errors left unresolved
If a later stage was requested but skipped (e.g., user asked to deploy but only publish succeeded), call it out explicitly in the next-steps section.
Anti-patterns
These pitfalls are not already covered by the Critical Rules. For rules stated as positive requirements, see the Critical Rules section at the top.
- Don't import service classes from the package root — use the subpath (e.g.,
@uipath/uipath-typescript/assets).
- Don't use the deprecated dot-chain
sdk.entities.getAll() — use constructor DI: new Entities(sdk).
- Don't delete
.uipath/ between publish and deploy — deploy reads app.config.json written by publish.
