How to make live a GQL schema?

In the Writing the GQL Schema section, we wrote the application’s GQL schema. Now, we need to initialize a new npm project. For the sake of simplicity and in order to focus on the GQL logic only, we can build it by running the following code:

mkdir family-gql
cd family-gql/
npm init --yes
npm install fastify@4 mercurius@11

We are ready to create our first file, gql-schema.js. Here, we can just copy-paste the GQL schema we wrote in the previous section:

module.exports = `
# the GQL Schema string

Before proceeding further, it is worth mentioning that there are two different ways to define a GQL schema with Node.js:

  • Schema-first: The GQL schema is a string written following the GQL specification
  • Code-first: The GQL schema is generated by an external tool, such as the graphql npm module

In this chapter, we will follow the schema-first implementation as it is the most generic and allows you to get a clear overview of...
