This is an example API, showing how to create a GraphQL endpoint in Node. The mutations are protected behind authentication provided by Okta. To follow along step-by-step, check out the blog post.
Prerequisites: Node.js.
To install this example application, run the following commands:
git clone [email protected]:oktadeveloper/okta-express-graphql-example.git
cd okta-express-graphql-example
npm installThis will install a local copy of the project. You will need to set up some environment variables before the app will run properly.
To integrate Okta's Identity Platform for user authentication, you'll first need to:
- Sign up for a free Okta Developer account
- You will get a URL similar to
https://dev-123456.oktapreview.com.- Save this URL for later
- You will also use this URL to login to your Okta account
You will need to create an application in Okta:
- Log in to your Okta account, then navigate to Applications and click the Add Application button
- Select Web and click Next
- Give your application a name (e.g. "GraphQL Express")
- Change the Base URI to
http://localhost:4000/and the Login redirect URI tohttp://localhost:4000/implicit/callback, then click Done - Save your Client ID and Client Secret for later
Your Okta application should have settings similar to the following:
You will also need to create an API token in Okta:
- Log in to your Okta account, then navigate to API > Tokens and click the Create Token button
- Enter a name that will help you remember what this is used for (e.g. "GraphQL Express")
- Save the provided token value for later
- This will only be displayed once. If you lose it, you will need to create another API token
Now create a file called .env in the project root and add the following variables, replacing the values with your own from the previous steps.
.env
HOST_URL=http://localhost:4000
OKTA_ORG_URL=https://{yourOktaOrgUrl}
OKTA_CLIENT_ID={yourClientId}
OKTA_CLIENT_SECRET={yourClientSecret}
OKTA_TOKEN={yourOktaToken}You also need an app secret. One way to get a random APP_SECRET is to use the following commands, which will generate a random value and add it to your .env file.
npm install -g uuid-cli
echo "APP_SECRET=`uuid`" >> .envNow you can run the GraphQL server with the following command:
npm startOnce you're up and running, you can get a nice user interface with built-in documentation by going to the GraphQL Playground and entering in http://localhost:4000/graphql. Queries shouldn't require authentication, but if you want to run a mutation you'll need to authenticate first.
Go to http://localhost:4000/access-token. This should prompt you to log in to your Okta developer account if you haven't already. Once you're authenticated, the page should give you an access token that will look something like eyJraW...j5gsJQ, only much longer.
In the GraphQL Playground, click on HTTP HEADERS, then modify it to include an authorization header with your token. It should look like this:
{
"authorization": "Bearer eyJraW...j5gsJQ"
}Note: Again, the real token will be much longer. Just copy and paste it from the previous page.
Here are some examples to get you started. Feel free to play around with them and get creative.
query {
posts {
id
author {
id
firstName
lastName
}
body
}
}query {
post(id: 2) {
id
author {
firstName
posts {
id
body
}
}
body
}
}mutation {
submitPost(input: {
body: "Hello, world!"
}) {
id
body
author {
id
firstName
lastName
posts {
id
body
}
}
}
}This example uses the Okta Node SDK, the Okta JWT Verifier, and the Okta OIDC Middleware.
