This quick start guide will help you to start a new WunderGraph project from scratch, or add WunderGraph to an existing project.
Creating a new WunderGraph project
Integrating WunderGraph with an existing project
You can also easily integrate WunderGraph into your existing projects.
Now edit your
package.json and add the following scripts, so we can run the WunderGraph server.
Start the WunderGraph server
WunderGraph will now do some code generation and start the server. Head over to http://localhost:9991 and you should see the WunderGraph status page.
Now lets run one of the example queries, open the following URL in your browser: http://localhost:9991/operations/Country
You'll see a JSON response with a list of countries. Pretty cool, right? Let's take a look at how this works.
WunderGraph lives in the
.wundergraph directory by default. This is where you can configure your WunderGraph application and write your operations.
Let's take a look at the default configuration open
You can see that we have a single API configured, which is the Countries GraphQL API .
The API is introspected and added to the WunderGraph virtual graph, as you can see here:
Once it's added to the virtual graph, you can write operations against it.
Write your first operation
Operations are written in the
.wundergraph/operations directory. They can be written in Graphql or TypeScript. Let's check out the Countries operation, open
The input type and query are prefixed with
countries_ because we're using the
countries API namespace in the introspection config. This is to avoid naming conflicts when you add multiple APIs to your WunderGraph application.
We'll make a few improvements to the API. First, let's remove the
countries_ prefix from the result, so we can access the result without the
If you run the operation again, you'll see that the result is the same, but the countries can now be accessed without the
Now we can add some extra data to the result. Let's add the
currency fields to the result.
If you run the operation again, you'll see that the result now contains the
Awesome! You now have a basic understanding how WunderGraph works. The next step is to consume the API from your frontend, continue with one of our frontend quickstarts:
