strapi-plugin-slugify

A plugin for Strapi that provides the ability to auto slugify a field for any content type. It also provides a findOne by slug endpoint as a utility.

Requirements

The installation requirements are the same as Strapi itself and can be found in the documentation on the Quick Start page in the Prerequisites info card.

Supported Strapi versions

• v4.x.x

NOTE: While this plugin may work with the older Strapi versions, they are not supported, it is always recommended to use the latest version of Strapi.

Installation

npm install strapi-plugin-slugify

# or

yarn add strapi-plugin-slugify

Configuration

The plugin configuration is stored in a config file located at ./config/plugins.js.

Please note that the field referenced in the configuration file must exist. You can add it using the Strapi Admin UI. Also note that adding a field at a later point in time will require you to unpublish, change, save and republish the entry/entries in order for this plugin to work correctly.

A sample configuration

module.exports = ({ env }) => ({
  // ...
  slugify: {
    enabled: true,
    config: {
      contentTypes: {
        article: {
          field: 'slug',
          references: 'title',
        },
      },
    },
  },
  // ...
});

This will listen for any record created or updated in the article content type and set a slugified value for the slug field automatically based on the title field.

Note: To rewrite the same field (e.g. title is both a reference and a slug) use title as the field and references value.

Note: Compound slugs (basing the slug on multiple fields) can be achieved by passing an array of fields to the references property (e.g. references: ['date','title']).

IMPORTANT NOTE: Make sure any sensitive data is stored in env files.

Additional Requirement for GraphQL

Per #35 please ensure that the slugify plugin configuration is placed before the graphql plugin configuration.

contentTypes[modelName]field	The name of the field to add the slug	String	N/A	Yes
contentTypes[modelName]references	The name(s) of the field(s) used to build the slug. If an array of fields is set it will result in a compound slug	String or Array	N/A	Yes

Usage

Once the plugin has been installed, configured and enabled the configured content types will have the following additional functionality

Slugification

Any time the respective content types have an entity created or updated the slug field defined in the settings will be auto generated based on the provided reference field.

Find One by Slug

Hitting the /api/slugify/slugs/:modelName/:slug endpoint for any configured content types will return the entity type that matches the slug in the url. Additionally the endpoint accepts any of the parameters that can be added to the routes built into Strapi.

IMPORTANT The modelName is case sensitive and must match exactly with the name defined in the configuration.

Additional Requirements

Like all other created API endpoints the findSlug route must be allowed under User & Permissions -> Roles -> Public/Authenticated for the user to be able to access the route.

Examples

Example Request

Making the following request with the sample configuration will look as follows

REST

await fetch(`${API_URL}/api/slugify/slugs/article/lorem-ipsum-dolor`);
// GET /api/slugify/slugs/article/lorem-ipsum-dolor

GraphQL

{
  findSlug(modelName:"article",slug:"lorem-ipsum-dolor"){
    ... on ArticleEntityResponse{
      data{
        id
        attributes{
          title
        }
      }
    }
  }
}

Additionally if draftAndPublish is enabled for the content-type a publicationState arg can be passed to the GraphQL query that accepts either preview or live as input.

IMPORTANT Please beware that the request for an entry in preview will return both draft entries & published entries as per Strapi default.

{
  findSlug(modelName:"article",slug:"lorem-ipsum-dolor",publicationState:"preview"){
    ... on ArticleEntityResponse{
      data{
        id
        attributes{
          title
        }
      }
    }
  }
}

Example Response

If an article with the slug of lorem-ipsum-dolor exists the response will look the same as a single entity response

REST

Successful Response

{
  "data": {
    "id": 1,
    "attributes":{
      "title": "lorem ipsum dolor",
      "slug": "lorem-ipsum-dolor",
      "createdAt": "2022-02-17T01:49:31.961Z",
      "updatedAt": "2022-02-17T03:47:09.950Z",
      "publishedAt": null
    }
  }
}

Error Response

To be inline with Strapi's default behavior for single types if an article with the slug of lorem-ipsum-dolor does not exist a 404 error will be returned.

{
  "data": null,
  "error": { 
    "status": 404, 
    "name": "NotFoundError", 
    "message": "Not Found", 
    "details": {} 
  }
}
