Technologies you will use

Technical test:

1. Create a form in React in which user select multiple png/jpg/jpeg files to upload on server.

a. Take two input elements in that form. One is number type in which user enter the amount and the second is Date type in which user selects the Date.

b. Show file upload progress to user, in separate progress bar for each file

c. Post the form data on server and show the response to the user whether the data has been saved or not

2. On server side, in nodeJS, save the files on server and save data in mysql database.

3. On client side, in React add another web page to show form input data and uploaded files to user

4. Deliver solution in a way that it requires minimum effort (possibly one click) for us to run and assess it technically.

6. Keep the solution size file to minimum (possibly source files only) we are using latest version of reactjs and nodejs

Scalability:
7. Now on server side make it scalable which can allow 500 users to perform this action simultaneously, test and verify before submitting.

Notes:

1. You can use separate api's for file uploading and data saving.

2. Don't use callback approach in both sides React and nodeJS. Use Promise based approach instead.

3. Keep a note of time it will take to complete the application.

4. email solution at support@bitvelocity.io

5. Use Typescript libraries for implementing the features.

6. Do not spend extra time on making client UI fancy, keep the UI really simple, reliability, code quality and documentaiton is more important

All the best.
