Plain SDK

TypeScript packages for building on Plain's API. This is a monorepo containing the following packages:

Package	npm	Description
@team-plain/graphql		Typed GraphQL client with auto-generated model classes
@team-plain/ui-components		UI component builder helpers
@team-plain/webhooks		Webhook parsing and signature verification

Install only what you need — each package is published independently:

npm install @team-plain/graphql
npm install @team-plain/ui-components  # requires @team-plain/graphql as peer
npm install @team-plain/webhooks       # standalone, no SDK dependency

Requires Node 24+. Supports both ESM and CJS.
