simple-multipart-formdata v1.0.2

simple-multipart-formdata

Installation :

npm install simple-multipart-formdata

- Simple API to parse multipart-formdata into a readable object.

- Only requires HTTP request as an input which then return an event emitter. This will emit data event when form-data is ready. You need to assign an event listener to consume data which is coming as a readable object.

Note : It will not work with static types such as files. This works really well with all other types.

Example

const { formation } = require('simple-multipart-formdata');

let    Form         =  formation( req ); 

Form.on( 'data' , (data)=> {

    // do something
    // data is readable object, containing parsed request body data
})

Explanation

formation( req ) get the HTTP request stream and return an event emitter which is fired when multipart-form-data has properly parsed.This is the main API of this module.

Form ( you can name this as you want ) is stored the return value which is an Event emitter

API

formation( [stream] )

return : emitter

Full Example :

HTTP Server which is handling incoming requests.

      else if(req.method == "POST"){

        let Info = {} ;
       
        let Form = formation( req );     /* 'formation' do the body parsing and return a event emitter which emit -
                                            when data is available */

        Form.on('data' , (data)=> { 
            Info = data ;
            console.log( data );  // to see how output looks like 
        });
       
        req.on( 'end' , ()=> {

            res.writeHead( 200 , { 'Content-Type': 'application/json'})
            res.end( JSON.stringify(Info) );         // to see the parsed form-data

        })
      
   }

Here is the relavent html code.

       <form action="http://localhost:8000" method="POST" enctype="multipart/form-data">
        
        <input type="text" name="MYtext">
        <input type="datetime-local" name="MYdatetime">
        <input type="month" name="MYmonth">
        <input type="time" name="Mytime">
        <input type="search" name="MYsearch">
       
        <input type="submit" name="SUBMITTED">

    </form>

Here is the Output looks like.

{
  MYtext: 'Gold Fish',
  MYdatetime: {
    date: '2021-10-01',
    year: '2021',
    month: '10',
    day: '01',
    time: '00:25',
    hour: '00',
    minute: '25'
  },
  MYmonth: { date: '2021-01', year: '2021', month: '01' },
  Mytime: { time: '20:15', hour: '20', minute: '15' },
  MYsearch: 'search for something',
  SUBMITTED: 'Submit'
}
