Now I will not be going too much into what GraphQL exactly is but what you should know is that it is a query language for your APIs that is fundamentally different from the good ol' RESTful APIs. In GQL, we make a post request to our API rather than making different requests for different endpoints.
For fetching different data, we can just make a post request to a single endpoint for the API specifying what data we need in the query that we pass in.
https://graphql.anilist.co
Since this is a going to be a very simple tutorial, I will be just fetching a small amount of data from the API, but you can add on to this and scale it up if you want to in your project.
Let's first install axios and instantiate it in our code.
const axios = require("axios");
Now let's start building our query where we specify what and how much data we want.
const query = `
query ($page: Int, $perPage: Int, $search: String) {
Page (page: $page, perPage: $perPage) {
pageInfo {
total
perPage
}
media (search: $search, type: ANIME, sort: FAVOURITES_DESC){
id
title {
romaji
english
native
}
type
genres
}
}
};`
Now let's break this down. query is the beginning of our query in which we have to initialize the variables that we want to use. By default, the API returns a single result object so if we want multiple results, we have to wrap our media query inside a Page query. The Page query also provides the pageInfo field which provides information about the current page and total results count.
The media query is where the magic happens. Here we can just pass in the variable we passed in our parent query to get corresponding results filtered by that search string. In my example, I am just fetching the id, title, type and the genres of top 3 anime based on users rating and the search query (at the time of writing) but you can fetch different kinds of data and apply multiple types of sorting. This is the type of flexibility that GraphQL offers making it much easier to make API calls. You can check out the Anilist GraphQL Reference guide here.
We can now pass in the values of the variables that we initialized in our query in a separate variables object. Here, I am just getting a single page of result with only 3 items.
let variables = {
search: query,
page: 1,
perPage: 3,
};
The main part of our code is done. Now we can combine all these blocks of code with our axios api call inside an async function and we will be DONE.
async function getAnime(query) {
const query = `
query ($page: Int, $perPage: Int, $search: String) {
Page(page: $page, perPage: $perPage) {
pageInfo {
total
perPage
}
media(search: $search, type: ANIME, sort: FAVOURITES_DESC) {
id
title {
romaji
english
native
}
type
genres
}
}
}
`;
let variables = {
search: query,
page: 1,
perPage: 3,
};
const headers = {
"Content-Type": "application/json",
Accept: "application/json",
};
const result = await axios({
method: 'post',
query,
variables,
headers
}).catch((err) => console.log(err.message));
This is how the result data will look like if I searched for "shingeki".
{
"data": {
"Page": {
"pageInfo": {
"total": 57,
"perPage": 5
},
"media": [
{
"id": 16498,
"title": {
"romaji": "Shingeki no Kyojin",
"english": "Attack on Titan",
"native": "進撃の巨人"
},
"type": "ANIME",
"genres": [
"Action",
"Drama",
"Fantasy",
"Mystery"
]
},
{
"id": 110277,
"title": {
"romaji": "Shingeki no Kyojin: The Final Season",
"english": "Attack on Titan Final Season",
"native": "進撃の巨人 The Final Season"
},
"type": "ANIME",
"genres": [
"Action",
"Drama",
"Fantasy",
"Mystery"
]
},
{
"id": 104578,
"title": {
"romaji": "Shingeki no Kyojin 3 Part 2",
"english": "Attack on Titan Season 3 Part 2",
"native": "進撃の巨人 3 Part.2"
},
"type": "ANIME",
"genres": [
"Action",
"Drama",
"Fantasy",
"Mystery"
]
},
{
"id": 30,
"title": {
"romaji": "Shin Seiki Evangelion",
"english": "Neon Genesis Evangelion",
"native": "新世紀エヴァンゲリオン"
},
"type": "ANIME",
"genres": [
"Action",
"Drama",
"Mecha",
"Mystery",
"Psychological",
"Sci-Fi"
]
},
{
"id": 99147,
"title": {
"romaji": "Shingeki no Kyojin 3",
"english": "Attack on Titan Season 3",
"native": "進撃の巨人 3"
},
"type": "ANIME",
"genres": [
"Action",
"Drama",
"Fantasy",
"Mystery"
]
}
]
}
}
}
That's… pretty much it. Now you know how to get data of your favorite anime with just a few lines of code. I also use this in my own project: AniKo (It looks really bad on mobile devices right now :/)
If you liked this tutorial you can like & share it or even buy me a coffee! Appreciated ;)
