NodeJS – How to Parse the FormData into an Array of Objects Using Multiparty NPM Package

How to parse the form-data into an array of objects using a multiparty npm package

FormData objects are used to capture HTML form and submit it using fetch or another network method. The FormData interface provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest.send() method. It uses the same format a form would use if the encoding type were set to “multipart/form-data”.

My client owns an online platform that connects the world’s trusted lawyers for international client needs. As a part of the tasks, the client wanted me to upload all the invoice files into the AWS bucket. While uploading one or more files, the contents of the files should be appended in FormData and sent to the backend. I was able to figure out all these steps. However, I did not know how to parse the FormData that comes from the request URL.

Upon adequate research and peer assistance, I found the right way to parse the FormData. I used the multiparty npm package. Using this package, FormData can be parsed easily. Moreover, when I used this function – form.parse(req, function() => {}) I was able to receive that fields and files array of objects.
