Question

I´ve the file cases.js to create the route I want:
const express = require("express");
const { requireSignin } = require("../controllers/auth");
const { getCases } = require("../controllers/cases");
const { scrapingData } = require("../scrapingData");
const router = express.Router();
router.get("/cases", requireSignin, scrapingData, getCases);
module.exports = router;
requireSignin from controllers/auth looks like this:
exports.requireSignin = expressJwt({
secret: process.env.JWT_SECRET,
userProperty: "auth",
});
scrapingData as middleware I have:
const updateMongoRecords = async () => {
mongoose.Promise = global.Promise;
mongoose.set("debug", true);
Case.deleteMany({}, (err, result) => {
if (err) {
console.log(err);
} else {
console.log("Successfully deleted all records");
}
});
const dataPath = Path.join(__dirname, "files", "covid-data.csv");
try {
let headers = Object.keys(Case.schema.paths).filter(
(k) => ["_id", "__v"].indexOf(k) === -1
);
await new Promise((resolve, reject) => {
let buffer = [],
counter = 0;
let stream = fs
.createReadStream(dataPath)
.pipe(csv())
.on("error", reject)
.on("data", async (doc) => {
stream.pause();
buffer.push(doc);
counter++;
// log(doc);
try {
if (counter > 10000) {
await Case.insertMany(buffer);
buffer = [];
counter = 0;
}
} catch (e) {
stream.destroy(e);
}
stream.resume();
})
.on("end", async () => {
try {
if (counter > 0) {
await Case.insertMany(buffer);
buffer = [];
counter = 0;
resolve();
}
} catch (e) {
stream.destroy(e);
}
});
});
} catch (e) {
console.error(e);
} finally {
process.exit();
}
};
exports.scrapingData = async (req, res, next) => {
const url = "https://covid.ourworldindata.org/data/owid-covid-data.csv";
const path = Path.resolve(__dirname, "files", "covid-data.csv");
const response = await Axios({
method: "GET",
url: url,
responseType: "stream",
});
response.data.pipe(fs.createWriteStream(path));
return new Promise((resolve, reject) => {
response.data.on("end", () => {
resolve(updateMongoRecords());
next();
});
response.data.on("error", (err) => {
reject(err);
});
});
};
And getCases.js inside controllers/cases I have:
const Case = require("../models/case");
exports.getCases = async (req, res) => {
const cases = await Case.find().then((cases) => res.json(cases));
};
With this code I am able to fetch in the route /cases all the cases in the client side (like postman) and it shows all of them. But the problem is that I can´t make any other requests (like signing out, which works fine if I don´t make the get request for the cases like before) afterwards because client (postman) gives the error: GET http://localhost:5000/signout
Error: connect ECONNREFUSED 127.0.0.1:5000
in case you want to see the code for signout is like this:
const express = require("express");
const { signup, signin, signout } = require("../controllers/auth");
const router = express.Router();
router.post("/signup", userSignupValidator, signup);
router.post("/signin", userSigninValidator, signin);
router.get("/signout", signout);
inside controllers/auth.js:
exports.signout = (req, res) => {
res.clearCookie("t");
return res.json({ message: "Signout successfully done" });
};
Any help on this??
