What is happs_boilerplate and what is it for?

happs_boilerplate is a development template for a Holochain app: it pairs a Holochain application DNA with a TypeScript web client that reaches the app through a GraphQL Apollo server. It exists to give developers a working starting point for that client-and-server arrangement, so a new project does not have to assemble it from scratch.

happs_boilerplate is a scaffold for building a Holochain app, described in the repository as a boilerplate with a GraphQL Apollo client-server model written in TypeScript. Its README states that the data layer follows the Apollo GraphQL tutorial, and the repository ships an application DNA alongside a web interface and a GraphQL server. It is a starting point for developers rather than an application people use directly.

In practice the template shows one way to put GraphQL between a user interface and a Holochain instance. A small GraphQL server runs alongside each Holochain node, and the browser interface sends its queries and mutations to that server instead of talking to the node itself. The README's own run sequence starts one Holochain node and one GraphQL server per person, which is how its example works.

The README documents running two agents locally, Alice and Bob, each with its own interface page and its own GraphQL endpoint for trying queries and mutations. The setup it describes uses the sim2h server and Apollo Engine keys typical of the project's period, and the repository has not been pushed to since early 2023, so it reads best as a historical example rather than a currently maintained stack. The repository README is the place to learn more.
