Ratings is a Strapi plugin that allows your users to post reviews.

Enable and manage user reviews for your content very easily!

Requirements

You should have installed an instance of Strapi v4.x.x

Installation

Run the following command in your project root:

npm install strapi-plugin-ratings

Then, rebuild the admin dashboard using the following command

npm run build

Configurarion

For your frontend to have access to the API, enable the following permissions for Ratings from Users & Permissions Plugin on your project settings:

For public, enable: count, find, getPageSize and getStats.

For authenticated, enable create, find and getUserReview.

Display user reviews on the frontend

Reviews can be displayed in the frontend in two ways:

1. Using the React components library strapi-ratings-client (recommended)
2. Build your custom frontend using the API endpoints, described as follows:

API

There are some Typescript interfaces that will help to get an idea of the data structures.

Reviews:

interface IReview {
  id: number,
  createdAt: string,
  comment: string | null,
  author: IAuthor | null,
  score: number,
}

Authors:

interface IAuthor {
  username: string,
  email: string,
  id: number
}

Content Stats

interface IStats {
  averageScore: number;
  reviewsCount: number | null;
}

The following endpoints are exposed to fetch and post reviews:

Get reviews for a content ID

Method: GET

Path: /api/ratings/reviews/:slug

Optional query parameters: start, ignoreCount

Returns:

{
  reviewsCount: number,
  averageScore: number,
  userReview: IReview | null,
  reviews: IReview[]
}

The parameter start indicates how many reviews to skip. This is for pagination purposes.

The parameter ignoreCount indicates whether or not to return the total number of reviews associated with the given slug.

Get review stats for a content ID

Method: GET

Path: /api/ratings/reviews/:slug/stats

Returns:

{
  averageScore: number,
  reviewsCount: number | null
}

Get the number of reviews associated with a given content ID

Method: GET

Path: /api/ratings/reviews/:slug/count

Returns:

{
  count: number
}

Post a review

Method: POST

Path: /api/ratings/reviews/:slug

Authentication: Bearer token

Payload:

{
  content: string
}

Returns:

{
  id: number
}

By default, every authenticated user can post reviews on any content.

In order to customize this behavior, e.g. allowing or disallowing a user from posting reviews, you must extend the service userCanPostReview from whithin register function in ./src/index.js. For example:

strapi.service("plugin::ratings.review").userCanPostReview = async (user, slug) => {
  /*
    Here you will check whether or not the user
    is allowed to post a review on this content ID
    and return either true or false.
  */
  return true
}

Notice that userCanPostReview will receive two parameters: the user from Users & Permissions Plugin, containing it’s id, username, confirmed, etc., and the slug, which is a string and refers to the content ID which the review is being posted on.

In case this function returns false, the response of the endpoint will be 403 (forbidden) with the text User cannot post a review on this content.

Get the page size

Method: GET

Path: /api/ratings/page-size

Returns:

{
  pageSize: number
}

General settings

The plugin allows to set how many reviews are returned per page by going to the Pagination section under Ratings Plugin of the Settings section.

The default page size is 10.

Management of reviews

Admin users are able to delete reviews from within the plugin page of the Strapi admin dashboard.

The plugin interface has two tabs: one for the latest reviews and one for reviews by content ID.

Roadmap and future plans

The plugin is pretty basic but it can be improved with more features and a better UI/UX. Collaborations and suggestions are very welcome.
