URL Structure and Multi-Tenant Hierarchy

The webapp implements a hierarchical URL structure that reflects the multi-tenant nature of Trigger.dev. Every resource is scoped to an organization, project, and environment, creating a nested routing pattern.

Sources: apps/webapp/app/utils/pathBuilder.ts1-504

URL Parameter Types

The routing system uses type-safe parameter types to represent entities in URLs:

Type	TypeScript Definition	Description	Example
`OrgForPath`	`Pick<Organization, "slug">`	Organization identifier	`{ slug: "acme-corp-a1b2" }`
`ProjectForPath`	`Pick<Project, "slug">`	Project identifier	`{ slug: "my-project-c3d4" }`
`EnvironmentForPath`	`Pick<RuntimeEnvironment, "slug">`	Environment identifier	`{ slug: "prod" }` or `{ slug: "dev-user123" }`
`v3RunForPath`	`Pick<TaskRun, "friendlyId">`	Task run identifier	`{ friendlyId: "run_abc123" }`
`v3SpanForPath`	`Pick<TaskRun, "spanId">`	Span identifier	`{ spanId: "span_xyz789" }`
`DeploymentForPath`	`Pick<WorkerDeployment, "shortCode">`	Deployment identifier	`{ shortCode: "deploy_xyz" }`
`TaskForPath`	`{ taskIdentifier: string }`	Task identifier	`{ taskIdentifier: "my-task" }`

These types use TypeScript's Pick utility to extract only the slug or identifier field from database models, ensuring path functions receive minimal, focused data.

Path Builder Utility

The pathBuilder.ts utility provides type-safe functions for generating URLs throughout the application. All URL generation goes through these functions to ensure consistency and prevent broken links.

Core Path Functions

Function Hierarchy by Scope:

Sources: apps/webapp/app/utils/pathBuilder.ts51-504

Path Function Implementation

All path functions follow a consistent pattern, building URLs from base paths:

Helper functions extract slug values:

URL Parameter Validation

The system uses Zod schemas to validate URL parameters in route loaders. Each schema extends the previous one, building a hierarchy:

Schema	Parameters	TypeScript Type	Purpose
`OrganizationParamsSchema`	`organizationSlug: string`	`{ organizationSlug: string }`	Validates organization routes
`ProjectParamSchema`	`organizationSlug, projectParam`	`{ organizationSlug: string, projectParam: string }`	Validates project routes
`EnvironmentParamSchema`	`organizationSlug, projectParam, envParam`	`{ organizationSlug: string, projectParam: string, envParam: string }`	Validates environment routes
`v3TaskParamsSchema`	Above + `taskParam`	`EnvironmentParamSchema & { taskParam: string }`	Validates task routes
`v3RunParamsSchema`	Above + `runParam`	`EnvironmentParamSchema & { runParam: string }`	Validates run detail routes
`v3SpanParamsSchema`	Above + `spanParam`	`v3RunParamsSchema & { spanParam: string }`	Validates span detail routes
`v3DeploymentParams`	Above + `deploymentParam`	`EnvironmentParamSchema & { deploymentParam: string }`	Validates deployment routes
`v3ScheduleParams`	Above + `scheduleParam`	`EnvironmentParamSchema & { scheduleParam: string }`	Validates schedule routes

Slug Generation and Collision Handling

Organizations and projects use unique slugs in URLs. Slugs are generated from user-provided names with collision detection and retry logic.

Organization Slug Generation

The createOrganization function generates slugs using a combination of the user-provided title and a 4-character random suffix:

Convert title to slug format using the slug library
Generate a 4-character suffix using nanoid with alphabet 1234567890abcdef
Check database for existing slug
If collision detected, retry up to 100 times
Create organization record with unique slug

Sources: apps/webapp/app/models/organization.server.ts18-77

Project Slug Generation

Project slug generation follows the same pattern:

Both use recursive retry logic with an attemptCount parameter that throws an error after 100 attempts, though in practice collisions are extremely rare due to the 4-character suffix (65,536 possible combinations).

Sources: apps/webapp/app/models/project.server.ts19-107

SideMenu Component

The SideMenu component provides the primary navigation interface, displaying organization/project selection, environment switching, and navigation links for all main sections.

SideMenu Structure

Sources: apps/webapp/app/components/navigation/SideMenu.tsx112-350

The SideMenuItem component renders each navigation link with consistent styling and active state detection:

Menu Item	Icon	Path Function	Active Color
Tasks	`TaskIconSmall`	`v3EnvironmentPath`	`text-tasks`
Runs	`RunsIconExtraSmall`	`v3RunsPath`	`text-runs`
Batches	`Squares2X2Icon`	`v3BatchesPath`	`text-batches`
Schedules	`ClockIcon`	`v3SchedulesPath`	`text-schedules`
Queues	`RectangleStackIcon`	`v3QueuesPath`	`text-queues`
Deployments	`ServerStackIcon`	`v3DeploymentsPath`	`text-deployments`
Test	`BeakerIcon`	`v3TestPath`	`text-tests`

Sources: apps/webapp/app/components/navigation/SideMenu.tsx218-266

ProjectSelector Component

The ProjectSelector component at the top of the SideMenu provides organization and project switching via a Popover menu.

Component Structure:

Key implementation details:

SwitchOrganizations submenu:

Uses a nested Popover with hover-based opening:

The component features:

Auto-close on navigation via useEffect watching navigation.location?.pathname
Hover-based submenu for switching organizations with 150ms delay on mouse leave
Conditional rendering of Usage button based on isManagedCloud feature flag
Plan display showing "Free" or subscription plan title from currentPlan
Visual feedback on selected project using isSelected prop and FolderOpenIcon vs FolderIcon

Sources: apps/webapp/app/components/navigation/SideMenu.tsx352-597

Header Scroll Detection

The SideMenu implements scroll-based header border visibility:

This creates a subtle visual indicator when the menu is scrolled, showing a border under the header section.

Sources: apps/webapp/app/components/navigation/SideMenu.tsx119-138

Route Matching and Data Loading

The webapp uses Remix's route matching system with custom hooks to access loader data throughout the component tree.

useMatchesData Hook

The useMatchesData utility searches all matched routes for specific loader data:

This hook:

Accepts string or array of route IDs to search for
Returns first match using reduce to short-circuit on first found
Optional debug mode logs all matching routes when debug: true
Enables data access from parent route loaders without prop drilling

Remix's useMatches() returns all currently matched routes in the route hierarchy, allowing any component to access data from parent loaders.

Sources: apps/webapp/app/utils.ts44-66

Specialized hooks provide type-safe access to organization, project, and environment data from route loaders.

Hook Overview:

Hook	Route Match ID	Returns	Throws if Missing
`useOptionalOrganizations`	`organizationMatchId`	`MatchedOrganization[]` or `undefined`	No
`useOrganizations`	`organizationMatchId`	`MatchedOrganization[]`	Yes (invariant)
`useOptionalOrganization`	`organizationMatchId`	`MatchedOrganization` or `undefined`	No
`useOrganization`	`organizationMatchId`	`MatchedOrganization`	Yes (invariant)
`useOptionalProject`	`organizationMatchId`	`MatchedProject` or `undefined`	No
`useProject`	`organizationMatchId`	`MatchedProject`	Yes (invariant)
`useOptionalEnvironment`	`organizationMatchId`	`MatchedEnvironment` or `undefined`	No
`useEnvironment`	`organizationMatchId`	`MatchedEnvironment`	Yes (invariant)
`useIsImpersonating`	`organizationMatchId`	`boolean`	No

Change detection hooks:

These hooks enable components to react to organization or project changes via callback functions.

Environment Selection Logic

When a user navigates to a project without specifying an environment, the system automatically selects the most appropriate environment using SelectBestEnvironmentPresenter.

Automatic environment redirect:

Route implementation:

The SelectBestEnvironmentPresenter selection logic prioritizes:

User's personal DEVELOPMENT environment (matched by orgMember.userId)
PRODUCTION environment (if no personal dev environment)
Any available environment (fallback)

This ensures users are directed to their personal development environment when available, or to the shared production environment otherwise.

Sources: apps/webapp/app/routes/_app.orgs.$organizationSlug.projects.$projectParam._index/route.tsx1-44 apps/webapp/app/presenters/SelectBestEnvironmentPresenter.server.ts

Layout Components

The AppLayout module provides container components that structure the page layout and work with the navigation system.

Layout Component Hierarchy

Layout Components:

Component	Purpose	Key Classes
`AppContainer`	Root container for entire app	`grid h-full w-full grid-rows-1 overflow-hidden`
`MainBody`	Contains page content next to sidebar	`grid grid-rows-1 overflow-hidden`
`PageContainer`	Wrapper for page with header and body	`grid-rows-[auto_1fr] overflow-hidden`
`PageBody`	Scrollable content area	`overflow-y-auto scrollbar-thin` with padding
`MainCenteredContainer`	Centered container for auth/settings pages	`mx-auto max-w-xs md:mt-[22vh]`

Sources: apps/webapp/app/components/layout/AppLayout.tsx1-86

URL Safety and Sanitization

The routing system includes protection against open redirect vulnerabilities through the sanitizeRedirectPath utility:

This function ensures that redirect paths:

Are non-empty strings
Start with / but not //
Cannot be parsed as absolute URLs
Only contain valid relative path characters

This prevents malicious redirect attacks where an attacker might try to redirect users to external sites via query parameters.
