I wrote this code in my node app
const express = require("express");
const cors = require("cors");
const pool = require("./db");
const app = express();
//middleware
app.use(cors);
//access req.body
app.use(express.json());
app.get("/", async (req, res) => {
try {
res.json("response from server");
// const allCompanies = await pool.query("SELECT * FROM COMPANIES");
// res.json(allCompanies.rows);
} catch (error) {
console.log(error.message);
}
});
const port = 1337;
app.listen(port, () => {
console.log(`Server is starting on port ${port}`);
});
In my terminal it says its running on 1337 however when i try to connect to postman it leaves me hanging? never had this problem before.
const express = require("express");
const cors = require("cors");
const app = express();
app.use(cors());
The problem was that you were not calling the cors function on your app.use middleware.
If you change the code to
app.use(cors());
It should work.
Express Documentation
When i want to read a file in node js it won't display the file in the browser when I execute.
and in the terminal says no such file or directory while I use the exact file path anyone can answer this why?
Here is the code:
const express = require('express');
const app = express();
const fs = require('fs');
const bodyParser = require('body-parser');
const CORS = require('cors');
let port = 3000;
app.use(CORS());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false}));
app.use(express.static('Docs'));
app.get('/', (req, res) => {
res.json({name: 'waris', favFood: 'Pizza'})
fs.readFile('./docs/index.html', (err, data) => {
if(err){
console.log(err)
}else{
res.send(data);
}
})
})
app.listen(port, () => {
console.log(`Running on port ${port}`);
})
I created a mean stack application, I am deploying it in a virtual machine
the problem is that I need to change the localhost(localhost:4200) address to the ip of the machine 10.10.10.15(10.10.10.15:4200) I don't know how to do it
const path = require("path");
const express = require("express")
const mongoose = require("mongoose")
const db = require("./db/db")
const header_middleware = require("./middlewares/header")
const postRouter = require("./Routes/post");
const userRoutes = require("./Routes/user");
const profileRoutes = require("./Routes/profile");
var cors = require('cors');
const app = express()
app.use(cors({origin: '*'}));
const PORT = process.env.PORT || 3000
app.use(express.json())
app.use(header_middleware)
const directory = path.join(__dirname, './images');
app.use("/images", express.static(directory));
// app.use("/", express.static(path.join(__dirname, 'angular')));
app.use("/api/posts", postRouter)
app.use("/api/user", userRoutes);
app.use("/api/profile", profileRoutes);
app.get('/test', (req, res) => {
res.send('Hello World!')
})
app.listen(PORT, (req,res) => {
console.log(`app is listening to PORT ${PORT}`)
})
Instead of using your ip you can use your computer-name:4300 in your browser for example laptop-xxxxx:4300. To find your computer name you can go to about in your settings and it will say the name of your computer. If that doesn’t work check this answer out: https://stackoverflow.com/a/34659560/11365636
I tired to solve this problem, when I browse localhost:5000 I got error like
Cannot GET /

the problem here is you have no route at the root /
you have to add either your routes you defined or define a root route
