    npx @newmo/graphql-fake-server --schema api.graphql
    # Use a config file
    npx @newmo/graphql-fake-server --config graphql-fake-server.config.js

HTTP APIs

/graphql and /query

GraphQL Endpoint.

You need to set sequence-id header to identify the sequence with the request.

await fetch(`${urls.fakeServer}/graphql`, {
    method: "POST",
    headers: {
        "Content-Type": "application/json",
        "sequence-id": sequenceId,
    },
    body: JSON.stringify({
        operationName: "CreateBook",
        query: `
        mutation CreateBook($title: String!) {
          createBook(title: $title) {
            id
            title
          }
        }
    `,
        variables: {
            title: "The Great Gatsby",
        },
    }),
});

/fake

Register the fake data for sequence-id and operationName.

await fetch(`${urls.fakeServer}/fake`, {
    method: "POST",
    headers: {
        "Content-Type": "application/json",
        "sequence-id": sequenceId,
    },
    body: JSON.stringify({
        type: "operation",
        operationName: "CreateBook",
        data: {
            createBook: {
                id: "new-id",
                title: "new BOOK",
            },
        },
    }),
});

/fake/called

Return request and response for the request with sequence-id and operationName.

const calledResponse = await fetch(`${urls.fakeServer}/fake/called`, {
    method: "POST",
    headers: {
        "Content-Type": "application/json",
        "sequence-id": sequenceId,
    },
    body: JSON.stringify({
        operationName: "CreateBook",
    }),
});

Config

You can customize the configuration by --config option.

npx @newmo/graphql-fake-server --config graphql-fake-server.config.mjs

Example of the config file: graphql-fake-server.config.mjs

export default {
    schemaFilePath: "./api/api.graphql",
    ports: {
        fakeServer: 4000,
        apolloServer: 4002,
    },
    maxRegisteredSequences: 1000,
    maxFieldRecursionDepth: 9,
    maxQueryDepth: 10,
    defaultValues: {
        String: "string",
        Int: 1,
        Float: 1.1,
        Boolean: true,
    },
};
