How to handle next api route using dynamic id - next.js

Question

I am using NextJS and created three layers that separate the logic.
The purpose is to minimise the error handling to the getServerSideProps section. I want to get all the lists from the database.
In the first layer, in the API route I created a folder called get-all-lists and a file [userId].js. The get request will be 'http://localhost:3000/api/get-all-lists/iudga937gr8'. Bellow there is the api route that get all the lists with the help of Prsima. It is working perfectly
import prisma from '../../../lib/prisma'
export default async function handler(req, res) {
const { userId } = req.query;
if (req.method === 'GET') {
try {
const shoppingLists = await prisma.List.findMany({ where: { userId: userId }});
res.status(200).json({lists: shoppingLists});
}
catch (error) {
console.log(error);
res.status(500).json({ message: 'Something went wrong. Please try again'});
}
}
else {
res.status(500).json({message: 'Invalid method requested!'});
}
}
The next layer, is the abstraction one which sent the final result to getServerSideProps. I created this because I need to fetch alot of requests and it would be too messy...
export const getAllLists = async userId => {
try {
const lists = await axios.get(`/api/get-all-lists/${userId}`);
return lists;
}
catch (error) {
console.log('Abstraction layer error: ', error);
return 'Something went wrong. Please try again later';
}
}
The problem arise here. In the postman I have the right result. In postman I use http://localhost:3000/api/get-all-lists/clbcpc0hi0002sb1wsiea3q5d and the server sent me the array specified.
But this function does not work and send me this error:
Abstraction layer error: TypeError [ERR_INVALID_URL]: Invalid URL

input: '/api/get-all-lists/clbcpc0hi0002sb1wsiea3q5d',
code: 'ERR_INVALID_URL'
}
I also tried to paste the localhost in the browser and it have no problem.

You could extract the functionality into /lib/getAllList.js:
import prisma from './prisma';
export default async function getAllLists(userId) {
return await prisma.List.findMany({ where: { userId: userId }});
}
Then use it in your API route:
import getAllLists from '../../../lib/getAllLists';
export default async function handler(req, res) {
const { userId } = req.query;
if (req.method === 'GET') {
try {
const shoppingLists = await getAllLists(userId);
res.status(200).json({lists: shoppingLists});
}
catch (error) {
console.log(error);
res.status(500).json({ message: 'Something went wrong. Please try again'});
}
}
else {
res.status(500).json({message: 'Invalid method requested!'});
}
}
Then use it in getServerSideProps:
import getAllLists from 'path/to/lib/getAllLists';
export async function getServerSideProps(context) {
const { userId } = context.params;
const shoppingLists = await getAllLists(userId);
return {
props: {
shoppingLists,
},
};
}
