# GraphQL Gateway using GraphQL Mesh and Next.js API routes
|
|
|
|
This is a simple set up for Next.js using [GraphQL Mesh](https://www.graphql-mesh.com/docs/introduction) to build a GraphQL Gateway based on a REST API.
|
|
|
|
GraphQL Mesh is a framework that allows to build GraphQL Gateway server, based on one or multiple source APIs (REST, SOAP, gRPC, GraphQL or Databases).
|
|
|
|
```mermaid
|
|
graph TD;
|
|
subgraph AA [" "]
|
|
A[Mobile app];
|
|
B[Web app];
|
|
C[Node.js client];
|
|
end
|
|
subgraph BB [" "]
|
|
E[REST API];
|
|
F[GraphQL API];
|
|
G[SOAP API];
|
|
end
|
|
Z[GraphQL Gateway API on a Next.js API route];
|
|
A & B & C --> Z;
|
|
Z --> E & F & G;
|
|
```
|
|
|
|
Configuring GraphQL Mesh only requires installing the required packages and providing a `.meshrc.yaml` configuration file.
|
|
|
|
This project translate the PetStore REST API (https://petstore.swagger.io/) to a GraphQL API by simply providing the following configuration:
|
|
|
|
_[`.meshrc.yaml`](./.meshrc.yaml)_
|
|
|
|
```yaml
|
|
sources:
|
|
- name: PetStore
|
|
handler:
|
|
newOpenapi:
|
|
baseUrl: https://petstore.swagger.io/v2/
|
|
oasFilePath: https://petstore.swagger.io/v2/swagger.json
|
|
```
|
|
|
|
More information on GraphQL Mesh configuration and concepts [are available in our documentation](https://www.graphql-mesh.com/docs/getting-started/overview).

## How to use
|
|
|
|
Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init), [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/), or [pnpm](https://pnpm.io) to bootstrap the example:
|
|
|
|
```bash
|
|
npx create-next-app --example with-graphql-gateway with-graphql-gateway-app
|
|
```
|
|
|
|
```bash
|
|
yarn create next-app --example with-graphql-gateway with-graphql-gateway-app
|
|
```
|
|
|
|
```bash
|
|
pnpm create next-app --example with-graphql-gateway with-graphql-gateway-app
|
|
```
