(1/9/2023) Update: SvelteKit has recently introduced support for server-only load functions and Form actions to enable sending requests to the server.
I am looking to retrieve data from my database without allowing end users to access it through the API endpoint I have set up. I am curious about how I can directly query my database from a file within the lib folder and return the data accordingly. However, when attempting this approach, I encounter an error stating global not defined:
lib/db.js:
import dotenv from "dotenv";
dotenv.config();
import { MongoClient } from "mongodb";
const uri = process.env["MONGODB_URI"];
const options = {
useUnifiedTopology: true,
useNewUrlParser: true,
};
let client;
let clientPromise;
if (!uri) {
throw new Error("Please add your Mongo URI to .env.local");
}
if (process.env["NODE_ENV"] === "development") {
if (!global._mongoClientPromise) {
client = new MongoClient(uri, options);
global._mongoClientPromise = client.connect();
}
clientPromise = global._mongoClientPromise;
} else {
client = new MongoClient(uri, options);
clientPromise = client.connect();
}
export default clientPromise;
routes/items/index.js:
import clientPromise from "$lib/db";
export async function get() {
const client = await clientPromise;
const db = client.db();
const data = await db.collection("items").find({}).toArray();
const items = data.map(({ name }) => ({ name }));
if (items) {
return {
body: {
items,
},
};
}
}
My attempt: lib/stores/items.js
import clientPromise from "$lib/db";
import { writable } from "svelte/store";
export const items= writable([]);
const fetchItems = async () => {
const client = await clientPromise;
const db = client.db();
const data = await db.collection("items").find({}).toArray();
const items = data.map(({ name }) => ({ name }));
substances.set(items);
};
fetchItems();
Despite trying the aforementioned code in multiple locations, the recurring issue of global not defined persists on the client side.
I came across a similar query where someone faced the same problem, but I'm uncertain on how to create a helper file to address this issue.
