About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

GraphQL Code Generator analyzes GraphQL schemas plus query, mutation, subscription, and fragment documents to generate TypeScript types, client helpers, resolver types, and other artifacts through plugins and presets.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Generate types from both schemas and actual operation documents

The generator can combine schema information with real queries and fragments so generated types reflect the operations an application actually executes.

Sources: [2][3]

Compose output through plugins and presets

TypeScript, React, Angular, resolver, and other plugins or presets can be selected to match frontend and backend requirements.

Sources: [2][3]

For reducing drift between GraphQL contracts and application code

It fits teams that want schema changes to flow into generated frontend and backend types rather than maintaining those definitions manually.

Sources: [2]

Check plugin resolution and duplicate GraphQL packages in monorepos

Workspace hoisting can prevent the CLI from locating plugins, and duplicate GraphQL versions can produce type incompatibilities. Inspect the dependency tree in monorepo setups.

Supplemental curator note

The root `0.0.0` version belongs to the private monorepo package and is not the published CLI version. `@graphql-codegen/cli` is currently 7.4.2 and requires Node.js 16+. Because plugins are loaded dynamically, pnpm/Yarn workspaces should verify that plugins resolve at the level visible to the CLI.

Try it in 3 steps

  1. 1

    Install GraphQL and the Codegen CLI

    Follow the official quick start and add GraphQL plus the Codegen CLI.

    pnpm add graphql && pnpm add -D @graphql-codegen/cli
  2. 2

    Generate an interactive configuration

    Answer prompts for the schema, documents, plugins, and generated output path.

    pnpm graphql-codegen init
  3. 3

    Run code generation

    Use the generated config to produce types and client/server artifacts from GraphQL contracts.

    pnpm graphql-codegen
