# storyblok-graphql-codegen-terraform

This is a plugin for GraphQL Codegen that outputs your schema to Storyblok resources in Terraform.

This terraform code is dependent on the [Storyblok Terraform provider](https://registry.terraform.io/providers/labd/storyblok/latest).

For an example output see [the example output terraform file](examples/output/example.tf).

For more information on the Storyblok Terraform provider, see the documentation on the [terraform registry](https://registry.terraform.io/providers/labd/storyblok/latest/docs).

# codegen.yml

A basic example:

```yml
overwrite: true
config:
  sort: false
schema:
  - storyblok-graphql-codegen-terraform
  - ./schemas/example.graphql
hooks:
  afterAllFileWrite:
    - terraform fmt
generates:
  terraform/example.tf:
    plugins:
      - storyblok-graphql-codegen-terraform
    config:
      space_id: 123
      sort_resources: true
```

## Configuration options
- `sort_resources` can be used to sort the resources in the terraform output. This can be used to avoid random sorting which can cause differences in your git changes each time you run the codegenerator.<br>
It is also adviced to set the global `sort` option to `false` since that will also sort the field definitions, which impacts the Storyblok UI itself.

# Your Graphql file

Basic example:

```graphql
# For root content types, add the `@storyblok(type: contentType)` directive
type Page @storyblok(type: contentType) {
  # Add a `@storyblokField` directive to add extra configuration for a field such as translations
  seoTitle: String @storyblokField(translatable: true, section: "SEO")
  seoDescription: String @storyblokField(translatable: true, section: "SEO")

  blocks: [Block] @storyblokField
}

union Block = MarkdownBlock | BannerBlock

# By default a type is a nested Storyblok component
type MarkdownBlock @storyblok {
  content: String @storyblokField(format: markdown, translatable: true)
}

type BannerBlock @storyblok(icon: block_image) {
  title: String @storyblokField(translatable: true)
  link: StoryblokLink @storyblokField
  image: StoryblokAsset! @storyblokField(filetypes: [image])
}

type ProductListBlock @storyblok {
  title: String @storyblokField(translatable: true)
}

type Article @storyblok {
  # This field will be ignored
  systemField: String
  date: Date @storyblokField
  author: String @storyblokField
  content: String @storyblokField(format: markdown, translatable: true)
}
```

## Advanced examples

### Tabs and Sections

Fields can be grouped into tabs and/or sections with corresponding storyblokField arguments.

```graphql
type A @storyblok {
  a: String @storyblokField(tab: "my-tab")
  b: String @storyblokField(tab: "my-tab")
  c: String @storyblokField(section: "my-section")
}
```

### Story Option Type

A story option type renders a dropdown list with available stories.

To create an option field with a story reference, create a field that references to `contentType` or `universal`.

```graphql
type A @storyblok {
  story: Story @storyblokField(folder: "{0}/some-folder")
}

type Story @storyblok(type: contentType) {
  name: String @storyblokField
}
```

Similarly, you'll get an options field if you provide an array.
Furthermore, the reference may also be a union type.
But if so, all types of the union type must either be a `contentType` or a `universal` type.

# Your resolvers file

This repository also contains a set of resolvers that can be used to do a couple of things:

- resolve internal and external links
- resolve an `id` field (based on the `_uid` field)
- resolve single blok fields
- resolve rich text as a serialized JSON string
- resolve union types
- resolve stories for single and multiple option fields

## Usage

```ts
import { logger } from '@commerce-backend/observability'
import { mergeResolvers } from '@graphql-tools/merge'
import {
  storyblokResolvers,
  updateContext,
} from 'storyblok-graphql-codegen-terraform/resolvers'
import StoryblokClient from 'storyblok-js-client'
import { typeDefs } from './typedefs.js'

const client = new StoryblokClient({
  accessToken: process.env.STORYBLOK_ACCESS_TOKEN,
})

export const customResolvers = {
  Query: {
    contentPage: (_parent, args, context, _info) =>
      client
        .get(`cdn/stories/pages/${args.path}`, {
          resolve_links: 'url', // this is required for the link resolver to work
          resolve_relations: ['content_page.usps'], // TODO: make this dynamic
        })
        // Use the update context so the resolvers can resolve links and story options
        .then(updateContext(context))
        .then((response) => ({
          ...response.data?.story.content,
          pageId: response.data?.story.id,
        })),
  },
}

const resolvers = mergeResolvers([
  // include all storyblok resolvers
  storyblokResolvers(typeDefs, {
    // optionally modify the relative story paths for the link resolver
    slugResolver: (fullPath) => fullPath.split('/pages/')?.[1] ?? fullPath,
  }),
  // add your own resolvers
  customResolvers,
])

export default resolvers
```
