GraphQL Playground HTML

A package that renders the HTML for the GraphQL Playground IDE, used by middleware integrations (Express, Koa, etc.). Current stable version is 1.6.30. Low release cadence (maintenance mode). Key differentiator: provides an interactive GraphQL IDE with subscriptions, docs, and collaboration features. Security: severe XSS vulnerability in versions before 1.6.22 requires sanitization of user input passed to renderPlaygroundPage().
