I want to make a ".json" page with the data I pulled. ut Code
app.get("/:user_id", async (req, res) => {
let items = [];
await msgData.find({ userId: req.params.user_id }).then((e) => {
e.map((e) => {
for (const [key, value] of e.msgChannelsMsgCount.entries()) {
items.push({ guildId: e.guildId, channel: key, msgCount: value });
}
});
});
res.write(JSON.parse(items));
});
Mongoose Schema
import { mongoose } from "./../../dist/tools.js";
const { model, Schema } = mongoose;
const schema = new Schema({
userId: String,
guildId: String,
msgCount: Number,
msgChannelsMsgCount: Map,
});
const msgdatas = model("msgdatas", schema);
export default msgdatas;
Mongo Output

res.write(JSON.parse(items)); to res.write(items); would work just fine.
try:
app.get("/:user_id", async (req, res) => {
let items = [];
await msgData.find({ userId: req.params.user_id }).then((e) => {
e.map((e) => {
for (const [key, value] of e.msgChannelsMsgCount.entries()) {
items.push({ guildId: e.guildId, channel: key, msgCount: value });
}
});
});
res.write(JSON.stringify(items, null, ' '));
});
Welcome to the Stack Overflow!
When you use JSON.parse(<input>) It read string input then turns that string into JS object format.
As an example:
{
"body": 5
}
//becomes
{
body: 5
}
which makes it possible for you to use the objects' body as object.body
To send json data you should use res.json(items) built-in express method
