Strapi part 2: GraphQL and Content Management

Published: Nov 2, 2023 by Isaac Johnson

Earlier this week we looked into setting up an on-prem Strapi instance. The whole reason for a Content Management System (CMS) is to, well, store some content.

Today we’ll create a simple Album Catalog and populate it with data (I’ll use some of my latest LPs purchased). We can then setup the GraphQL plugin and show how to use it.

GraphQL setup

Let’s look up the install command from the marketplace

The install command:

$ npm install @strapi/plugin-graphql --save

We also need to create a plugins.js file

builder@LuiGi17:~/strapi_k8s2/strapi-project$ vi config/plugins.js
builder@LuiGi17:~/strapi_k8s2/strapi-project$ cat config/plugins.js
module.exports = {

      amountLimit: 100,
      apolloServer: {
        tracing: false,
      },
    },
  },
};

We can (re)build with Docker

Then push (look at my last post where I also show using Dockerhub if you want a free CR).

builder@LuiGi17:~/strapi_k8s2/strapi-project$ docker push harbor.freshbrewed.science/freshbrewedprivate/strapidev:v5
The push refers to repository [harbor.freshbrewed.science/freshbrewedprivate/strapidev]

I need to then edit the deploymnet

$ kubectl edit deployments strapi-deployment
deployment.apps/strapi-deployment edited

$ kubectl get deployments strapi-deployment -o yaml | grep image:
        image: harbor.freshbrewed.science/freshbrewedprivate/strapidev:v5

$ kubectl get pods | grep strapi
strapi-deployment-df94c8d6b-nxsz5                        1/1     Running   0                 3m3s

And I can see it was installed by going back to the Marketplace

/content/images/2023/10/strapi-17.png

I’ll clearly need to sort out the query and authorizaton, but we can see it’s responding the query browser (we’ll get to this later in the post)

/content/images/2023/10/strapi-18.png

Adding a Collection Type

In order to see some data, we need to provide some data.

We’ll click “Create New Collection Type”

/content/images/2023/10/strapi2-01.png

And we’ll call it ‘MusicCatalog’

/content/images/2023/10/strapi2-02.png

We’ll add some fields next like AlbumTitle (Text)

/content/images/2023/10/strapi2-03.png

AlbumArtist

/content/images/2023/10/strapi2-04.png

and Year

/content/images/2023/10/strapi2-05.png

When done, don’t forget to save!

/content/images/2023/10/strapi2-06.png

Now, we can go over the Content Manager to add some entries

/content/images/2023/10/strapi2-07.png

I’ll add the last two LPs I picked up

/content/images/2023/10/strapi2-08.png

Next, we need to expose this to the public Role. The UI here has changed over time. I’m using the latest as of today below.

Go to the Public Role and click Edit (Pencil Icon)

/content/images/2023/10/strapi2-09.png

We are going to grant all on the Music Catalog plugin (our new collection)

/content/images/2023/10/strapi2-10.png

And do not forget to hit save in the upper right when done!

We can now see Music Catalog in the Playground context menu popup

/content/images/2023/10/strapi2-11.png

When we search, however, we see no results:

/content/images/2023/10/strapi2-12.png

The reason is we added some albums but left them as “draft”

/content/images/2023/10/strapi2-13.png

Let’s do it together - we’ll verify we cannot see the entries, check their status, publish the drafts and query again:

We can now see proper results

/content/images/2023/10/strapi2-14.png

If we wished to grab just one Album, we could fetch by ID

/content/images/2023/10/strapi2-15.png

We can use mutations to create entries (provided we enabled Create, as we did earlier, on the Public permissions)

mutation musicCatalogs{
   createMusicCatalog(data:{AlbumArtist:"Eric Clapton",AlbumTitle:"Slow Hands",Year:1977}) {
    data { attributes{AlbumTitle}}
  }
}

/content/images/2023/10/strapi2-16.png

This will create an entry in the Catalog, but only in draft state

/content/images/2023/10/strapi2-17.png

If I want to see my Albums including the ‘draft’ ones (preview vs live), I can add a filter:

query{
  musicCatalogs(publicationState:PREVIEW){
    data{
      attributes{
        AlbumTitle
      },
      id
    }
  }
}

/content/images/2023/10/strapi2-18.png

We can use GraphQL to publish:

mutation MusicCatalogs {
  updateMusicCatalog(id:"3", data:{ publishedAt: "2023-10-27T11:18:33.657Z"}) {
    data { attributes {publishedAt}}
  }
}

/content/images/2023/10/strapi2-19.png

This then makes it live

/content/images/2023/10/strapi2-20.png

Authentication

Recall how when we tried to connect to protected routes, it gave us a denied error (Forbidden Access)?

query{
  usersPermissionsRoles{
    data{
      id
    }
  }
}

/content/images/2023/10/strapi2-21.png

This should have given us a JWT

/content/images/2023/10/strapi2-22.png

But I can confirm the REST API also rejects what I know to be the right login, so perhaps there is some new auth bits

$ curl -X POST -H "Accept: text/javascript" -H "Content-Type: application/json" https://strapi.
freshbrewed.science/api/auth/local -d '{"identifier":"isaac@freshbrewed.science", "password":"TheRealPasswordHere"}'
{"data":null,"error":{"status":400,"name":"ValidationError","message":"Invalid identifier or password","details":{}}}

I just needed to confirm the user:

/content/images/2023/10/strapi2-23.png

Then the REST and GraphQL Playground worked

/content/images/2023/10/strapi2-24.png

Summary

We dove into setting up GraphQL in Strapi. We created a collection of albums and populated some data. We looked at querying all albums, some and creating a new entry. We also touched on publishing drafts and creating (and making live) users.

If you are interested in more, you can check out the original Strapi Blog article I used to learn, however it had a few nuances as it was written back in July (e.g. draft posts, unapproved users, and the Roles admin page).

The GraphQL Strapi Documentation is also a great place to learn features of the API.
