express reload page after post

To reload a page after a post in Express, you can follow these steps:

  1. First, you need to install the "body-parser" package. This package allows Express to parse the data sent in the request body. You can install it by running the following command in your terminal:
npm install body-parser
  1. After installing the "body-parser" package, you need to require it in your Express application. Add the following line of code at the top of your file:
const bodyParser = require('body-parser');
  1. Next, you need to use the body-parser middleware in your Express application. This middleware will parse the request body and make it available on the req.body object. Add the following line of code after creating your Express app:
app.use(bodyParser.urlencoded({ extended: false }));
  1. Now, you can handle the form submission and reload the page after the post. Inside your route handler for the POST request, you can redirect the user to the same page using the res.redirect() method. For example:
app.post('/submit', (req, res) => {
  // Handle the form submission here

  // Redirect the user to the same page
  res.redirect('/');
});

In this example, the user will be redirected to the root URL (/) after the form is submitted.

  1. Finally, you need to make sure that your form submits the data to the correct route. In your HTML form, set the action attribute of the form to the appropriate route. For example:
<form action="/submit" method="post">
  <!-- form fields go here -->
  <button type="submit">Submit</button>
</form>

Make sure to replace /submit with the actual route where you handle the form submission in your Express application.

By following these steps, you should be able to reload the page after a post in Express.
