App Store CLI - Cal.com

The App Store CLI provides tools for creating, editing, and managing Cal.com apps.

Installation

The CLI is included in the Cal.com monorepo:

cd packages/app-store-cli
yarn install

Commands

create

Create a new app in the app store.

yarn cli create

Interactive Mode

Run without flags to use the interactive wizard:

yarn cli create

You’ll be prompted for:

App name
Description
Category
Publisher name
Publisher email
Template selection

Non-Interactive Mode

Provide all options as flags for automation:

yarn cli create \
  --name "App Name" \
  --description "Short description" \
  --category <category> \
  --publisher "Your Name" \
  --email "[email protected]" \
  --template <template>

Options

--name

string

required

App display name. The slug is automatically generated from this.

--description

string

required

Short description (recommended max 10 words). Longer descriptions go in DESCRIPTION.md.

--category

string

required

App category. Options:

analytics - Analytics and tracking
automation - AI & Automation
calendar - Calendar integrations
conferencing - Video conferencing
crm - CRM integrations
messaging - Messaging services
payment - Payment processing
other - Other apps

--publisher

string

default:"Your Name"

Publisher name or company

--email

string

default:"[email protected]"

Publisher contact email

--template

string

required

Template to use. Options:

basic - Minimal installable app
event-type-app-card - Event type configuration card
booking-pages-tag - Booking page tags/scripts
event-type-location-video-static - Static video location
general-app-settings - App settings interface
link-as-an-app - External link redirect

--external-link-url

string

Required when using link-as-an-app template. The external URL to redirect to.

Example

yarn cli create \
  --name "Acme CRM" \
  --description "Sync bookings with Acme CRM" \
  --category crm \
  --publisher "Acme Corp" \
  --email "[email protected]" \
  --template basic

Output:

App created successfully!
Slug: acme-crm
App URL: http://localhost:3000/apps/acme-crm
Name: Acme CRM
Description: Sync bookings with Acme CRM
Category: crm

Next Step: Enable the app from http://localhost:3000/settings/admin/apps as an admin user.

create-template

Create a new app template (for Cal.com core developers).

yarn cli create-template

Templates are stored in packages/app-store/templates/ and used as scaffolds for new apps.

Most developers should use create, not create-template. Templates are for creating reusable scaffolds.

edit

Edit an existing app’s configuration.

yarn cli edit --slug <app-slug>

Options

--slug

string

required

The slug of the app to edit (matches the directory name)

Example

yarn cli edit --slug acme-crm

The interactive wizard will pre-fill existing values and allow you to modify:

App name
Description
Category
Publisher
Email
Template

Changing the slug will rename the app directory. Ensure no other processes are accessing the app files.

edit-template

Edit an existing template.

yarn cli edit-template --slug <template-slug>

delete

Delete an app from the app store.

yarn cli delete --slug <app-slug>

This permanently deletes the app directory and all its contents. This action cannot be undone.

Options

--slug

string

required

The slug of the app to delete

Example

yarn cli delete --slug acme-crm

delete-template

Delete a template.

yarn cli delete-template --slug <template-slug>

Build Commands

The CLI includes build commands for generating app registry files.

build

Generate app registry files once:

yarn build

This generates:

apps.metadata.generated.ts
apps.schemas.generated.ts
apps.server.generated.ts
apps.browser.generated.tsx
calendar.services.generated.ts
crm.apps.generated.ts
payment.services.generated.ts
video.adapters.generated.ts
analytics.services.generated.ts
redirect-apps.generated.ts

watch

Watch for changes and regenerate files automatically:

yarn watch

Useful during development. The CLI watches for:

New app directories
Changes to config.json files
Deleted app directories

Run yarn watch in a separate terminal during development to automatically regenerate registry files.

Package.json Scripts

The CLI package defines these scripts:

{
  "scripts": {
    "build": "ts-node --transpile-only src/build.ts",
    "cli": "ts-node --transpile-only src/cli.tsx",
    "watch": "ts-node --transpile-only src/build.ts --watch",
    "generate": "ts-node --transpile-only src/build.ts",
    "post-install": "yarn build"
  }
}

yarn build - Generate registry files
yarn cli <command> - Run CLI commands
yarn watch - Watch mode
yarn generate - Alias for build

Slug Generation

The CLI automatically generates slugs from app names:

Converts to lowercase
Replaces non-alphanumeric characters with hyphens
Example: “My Custom App” → “my-custom-app”

The slug is used as:

Directory name in packages/app-store/
App URL path: /apps/<slug>
Package name: @calcom/<slug>
App identifier in the database

File Generation

The build process scans all app directories and generates registry files that:

Import app metadata from config.json or _metadata.ts
Export app schemas from zod.ts
Register API handlers from api/index.ts
Map UI components from components/
Register services from lib/ (Calendar, CRM, Payment, Video, Analytics)

Generation Process

// For each app directory:
app-store/
├── my-app/
│   ├── config.json          → apps.metadata.generated.ts
│   ├── zod.ts              → apps.schemas.generated.ts
│   ├── api/index.ts        → apps.server.generated.ts
│   ├── components/         → apps.browser.generated.tsx
│   └── lib/
│       ├── CalendarService.ts  → calendar.services.generated.ts
│       ├── CrmService.ts       → crm.apps.generated.ts
│       ├── PaymentService.ts   → payment.services.generated.ts
│       └── VideoApiAdapter.ts  → video.adapters.generated.ts

E2E Mode

In E2E test mode (NEXT_PUBLIC_IS_E2E=1), calendar, video, and analytics services are disabled:

export const CalendarServiceMap = process.env.NEXT_PUBLIC_IS_E2E === '1' ? {} : {
  // ... calendar services
};

Validation

The CLI validates:

Category must be one of the valid categories
Template must exist in packages/app-store/templates/
External link URL required for link-as-an-app template
Config.json must be valid JSON and match AppMetaSchema

Templates

Templates are located in packages/app-store/templates/:

templates/
├── basic/
├── event-type-app-card/
├── booking-pages-tag/
├── event-type-location-video-static/
├── general-app-settings/
└── link-as-an-app/

Each template includes:

config.json - Template metadata
package.json - Dependencies
index.ts - Exports
zod.ts - Schemas
api/ - API handlers
components/ - UI components (if applicable)
static/icon.svg - Placeholder icon

Cross-Platform Support

The CLI supports Windows, macOS, and Linux:

Windows: Uses xcopy, move, mkdir, rd commands
Unix: Uses cp, mv, mkdir, rm commands

Platform detection is automatic based on os.platform().

Troubleshooting

Command Not Found

Ensure you’re in the correct directory:

cd packages/app-store-cli
yarn cli create

Invalid Template

List available templates:

ls packages/app-store/templates/

Invalid Category

Valid categories:

analytics
automation
calendar
conferencing
crm
messaging
payment
other

App Not Appearing

After creating an app:

Run yarn build to regenerate registry files
Restart the dev server
Enable the app in /settings/admin/apps

Directory Already Exists

The CLI won’t overwrite existing apps. Use edit to modify an existing app or delete to remove it first.

Advanced Usage

CI/CD Integration

Use non-interactive mode in CI pipelines:

yarn cli create \
  --name "$APP_NAME" \
  --description "$APP_DESCRIPTION" \
  --category "$APP_CATEGORY" \
  --publisher "$PUBLISHER_NAME" \
  --email "$PUBLISHER_EMAIL" \
  --template "$TEMPLATE_NAME"

Scripting

Create multiple apps with a script:

#!/bin/bash

apps=(
  "App One:Description 1:crm"
  "App Two:Description 2:payment"
)

for app in "${apps[@]}"; do
  IFS=':' read -r name desc category <<< "$app"
  yarn cli create \
    --name "$name" \
    --description "$desc" \
    --category "$category" \
    --template basic
done

Custom Templates

Create your own templates:

Use yarn cli create-template to create a template
Customize the scaffold files
Use it with --template your-template-name
