SWAPI Pagination with Node.JS, Express and Axios - node.js

Question

I wanted to fetch all people/films/etc. from SWAPI.
I tried a lot of things before finally get something usable. However, it only shows the first 10. people (in the people case)
const express = require("express");
const router = express.Router();
const axios = require("axios");
router.get("/people", (req, res) => {
axios
.get("https://swapi.dev/api/people/?format=json")
.then((data) => {
return res.send(data.data.results);
})
.catch((error) => {
console.log("error: ", error);
});
});
module.exports = router;
What I tried, thanks to a lot of searches from Stack Overflow, is this :
const express = require("express");
const router = express.Router();
const axios = require("axios");
router.get("/people", async (req, res) => {
let nextPage = `https://swapi.dev/api/people/`;
let people = [];
while (nextPage) {
res = await axios(nextPage)
const { next, results } = await res.data;
nextPage = next
people = [...people, ...results]
}
console.log(people.length) // 82
console.log(people) // shows what I wanted, all people !
return people;
});
module.exports = router;
When starting the server, the page doesn't finish loading (it's still loading at this moment), but the console.log managed to show exactly what I wanted.
So, how can I manage to show this in the page ?
My goal is to use that route for axios API calls from a React front-end (searching for a specific name)

Answer 1

Do not overwrite the res in your code and finish it with res.send:
let nextPage = `https://swapi.dev/api/people/`;
let people = [];
while (nextPage) {
let nextres = await axios(nextPage)
const { next, results } = await nextres.data;
nextPage = next
people = [...people, ...results]
}
console.log(people.length) // 82
console.log(people) // shows what I wanted, all people !
res.send(people);
