Serverless

Serverless platforms like AWS Lambda, Google Cloud Functions, and Azure Functions can generate PDFs using Format. Bundle the _generated directory into your deployment package alongside your function code.

AWS Lambda

Compile your documents and include the _generated directory in your Lambda deployment package:

npx format compile
zip -r function.zip dist/ _generated/ node_modules/ package.json

The node target works out of the box. Lambda functions have filesystem access, so format.pdf(doc) reads assets automatically.

Lambda@Edge / CloudFront Functions

For Lambda@Edge, use the worker target. Asset ZIPs must be hosted externally since Lambda@Edge has limited filesystem access and strict size limits:

npx format compile --preset edge

Upload assets.zip files to S3 and call setAssetsUrl at runtime. See Assets for details.

Google Cloud Functions

Same pattern as AWS Lambda. Compile, include _generated in your deployment, and use the node target:

npx format compile
gcloud functions deploy generate-pdf --runtime nodejs20 --trigger-http

Dependencies

The node target externalizes dependencies by default. Ensure your framework packages (react, react-dom or vue) are installed in your deployment package.

To reduce package size, bundle dependencies directly:

npx format compile --bundle date-fns @company/shared-utils
