Cloud Agents Starter

Build

pnpm build:packages      # Build all packages (required before dev)
pnpm build:integrations # Build integrations
pnpm clean:build        # Clean, reinstall, and rebuild

Lint & format

pnpm lint:check         # Check lint
pnpm lint:fix           # Auto-fix lint
pnpm format:check       # Check formatting
pnpm format             # Apply formatting
pnpm types:check        # TypeScript check

2. Packages (packages/*)

Run a package dev server

cd packages/<package-name>
pnpm dev

Common entrypoints:

Unit tests (Vitest)

pnpm test                           # Run all tests (packages + integrations)
pnpm vitest packages/*              # Packages only
pnpm vitest packages/api-client     # Single package
pnpm vitest packages/api-client --run  # Single run, no watch
pnpm test your-test-name            # Filter by test name

Test servers required: Some tests need @scalar/void-server (5052) and proxy-scalar-com (5051). Start them in a separate terminal:

pnpm script run test-servers

Then wait for ports: pnpm script wait -p 5051 5052

3. Integrations (integrations/*)

Run integration dev servers

pnpm --filter @scalar/express-api-reference dev
pnpm --filter @scalar/fastify-api-reference dev
pnpm --filter @scalar/nuxt dev
pnpm --filter @scalar/nextjs-api-reference dev

Integration tests

pnpm vitest integrations/*          # All integrations
pnpm vitest integrations/express   # Single integration

Python integrations (FastAPI, Django Ninja): Require Python 3.11. Run python run_tests.py in the integration directory.

Rust/Java/.NET: Have separate CI jobs; typically run via their native toolchains (cargo, mvn, dotnet).

4. E2E & Playwright

API Reference E2E

cd packages/api-reference
pnpm test:e2e              # Local (needs Playwright browser)
pnpm test:e2e:ci          # CI mode
pnpm test:e2e:update-snapshots  # Update snapshots

Components E2E (Storybook)

cd packages/components
pnpm test:e2e              # Local
pnpm test:e2e:ci           # CI mode
pnpm test:e2e:update       # Update snapshots

Nuxt E2E

pnpm --filter @scalar/nuxt test:e2e

Playwright uses PW_TEST_CONNECT_WS_ENDPOINT=ws://127.0.0.1:5001/ for browser connection in local runs.

5. Environment & Workflow

Environment variables

• CI: Set CI=1 for CI-like behavior (e.g. test servers, some Playwright runs).
• NODE_OPTIONS: openapi-parser tests use NODE_OPTIONS=--max_old_space_size=8192 for large specs.
• TEST_MODE=CDN: Used for CDN snapshot tests in api-reference.

Scripts (tooling/scripts)

pnpm script run test-servers   # Start void-server + proxy-scalar-com
pnpm script wait -p 5051 5052  # Wait for ports
pnpm script generate-readme    # Regenerate integration READMEs

Feature flags

This codebase does not use feature flags. Configuration is via package options, OpenAPI spec extensions, or environment variables as noted above.

6. Projects & Examples

• proxy-scalar-com (Go): cd projects/proxy-scalar-com && go run main.go (port 5051)
• Examples (examples/*): Each has its own pnpm dev (e.g. examples/web, examples/react)

7. CI Parity (run like CI)

To approximate CI locally:

pnpm install
pnpm build:packages
pnpm script run test-servers & pnpm script wait -p 5051 5052
pnpm vitest packages/* --silent
pnpm vitest integrations/* --silent
pnpm types:check
pnpm lint:check
pnpm format:check

8. Updating This Skill

When you discover new testing tricks, runbook steps, or environment requirements:

1. Add to the appropriate section (root, packages, integrations, E2E, environment).
2. Use concrete commands – copy-pasteable, with package names and paths.
3. Note edge cases – e.g. "Python integrations need Python 3.11", "openapi-parser needs NODE_OPTIONS".
4. Keep it minimal – only include what agents need to run and test quickly.
5. Cross-reference – if a step depends on another (e.g. test-servers before package tests), state it clearly.
