Creating the Movie Component

Creating the Movie Component

Learn how to render data retrieved from the backend in React.

We'll cover the following...

In this lesson, we’ll create a Movie component that will display the individual movie and its reviews:

import axios from "axios";

class MovieDataService{
    
   getAll(page = 0){ 
     return axios.get(`{{EDUCATIVE_LIVE_VM_URL}}:3000/api/v1/movies?page=${page}`)
   }

   get(id){ 
     return axios.get(`{{EDUCATIVE_LIVE_VM_URL}}:3000/api/v1/movies/id/${id}`)
   }   

   find(query, by = "title", page = 0){
     return axios.get(`{{EDUCATIVE_LIVE_VM_URL}}:3000/api/v1/movies?${by}=${query}&page=${page}`)
   }       

   createReview(data){
     return axios.post("{{EDUCATIVE_LIVE_VM_URL}}:3000/api/v1/movies/review", data)
   }
   updateReview(data){
     return axios.put("{{EDUCATIVE_LIVE_VM_URL}}:3000/api/v1/movies/review", data)
   }
   deleteReview(id, userId){
     return axios.delete("{{EDUCATIVE_LIVE_VM_URL}}:3000/api/v1/movies/review",
        {data:{review_id: id, user_id: userId}}
     )
   }
   getRatings(){
     return axios.get("{{EDUCATIVE_LIVE_VM_URL}}:3000/api/v1/movies/ratings")
   }    
}
export default new MovieDataService()
Initial files we will build on

In the components folder in the movie.js file, fill in the following code:

import React, {useState, useEffect} from 'react'
import MovieDataService from '../services/movies'
import { Link } from 'react-router-dom'
const Movie = props => {
  
    const [movie, setMovie] = useState({
      id: null,
      title: "",
      rated:"",
      reviews:[]
    })
  
    const getMovie = id =>{
      MovieDataService.get(id)
        .then(response => {
          setMovie(response.data)
          console.log(response.data)
        })
        .catch(e =>{
          console.log(e)
        })
    }
  
    useEffect(()=>{ 
      getMovie(props.match.params.id)
    },[props.match.params.id]) 
  
    return (
      <div>  
        
      </div>
    );
  }
  
  export default Movie;

Lines 7–12: We have a movie state variable to hold the specific movie we’re currently showing in the Movie component. We set its initial values to null, empty strings "", or an empty array [].

Lines 14–23: The getMovie() method calls the get() method of MovieDataService (in the ...
