Forms with NodeJS

What are the web forms?

Web forms are one of the main points of interaction between a user and a website or application. Forms allow users to enter data, which is typically sent to a web server for processing and storage.

Using express

We define a route using the GET method which will return our view of the form

app.get('/registro', (request, response) => {
    response.send('form');
})

We define a route using the POST method which will receive all the information supplied through the form. This information is received in the request object which has a body attribute that is where all the fields that come from our form are.

app.post('/registro', (request, response) => {
    console.log(request.body)
    console.log(request.files)
})

1. request.body: brings all the information from our inputs except the type "files".
2. request.files: brings all the information of files attached to our form. For example; pdf, images, documents.

Note: It is important to highlight that all our fields must have the attribute name defined in the label. Example: <input type="text" name="name" placeholder="Insert name">
