ngx-Form

This project was generated with angular-cli version 1.1.0.

The goal of this project is to submit a form with one file upload and two text fields. The form is submitted to back end, the file is stored in the uploads/forms/:userID and then the file name (string) is stored in MongoDB among the two text fields. At the end, the form ID is assinged to the signed in user ID (via Ref) for later viewing all the form fields and file in the front end. User profile image is stored at uploads/profiles/:userID.

Prerequisites

  1. MongoDB installed and running (http://mongodb.org)
  2. Node.js and NPM installed (http://nodejs.org)
  3. ImageMagick or GraphicsMagick installed, more info in gm page on how to install depending your Operating System. If installing ImageMagick on Windows, please check "Install Legacy Utitities (e.g. convert") during installation otherwise node will report errors.

Specs

  1. User login/signup using JSON Web Token (jwt) using Passport.
  2. User password reset via email (nodemailer & SendGrid) using HTML templates (welcome email included upon user registration).
  3. Toastr Notifications (& Error Handling).
  4. Multipart form submission with image preview before upload (some of the upload logic is taken from primeng ui).
  5. Storing images to file system.
  6. Storing image path to MongoDB among text fields.
  7. Triple check if image is actually a file by checking it's mime type in both back end and in front end (gm in back end checks if file is an image too by reading first bytes of the file, need to fix this to not allow form to be submitted at all).
  8. Double check for the image size in both back end and front end, file limit now is 5.000.000 bytes (5MB).
  9. Image resize server side using GraphicsMagick.
  10. Form deletion among the file from filesystem, user forms array is updated too.
  11. Edit form, user can edit the text inputs and the image or update only the image or update only the text fields.
  12. Admin area, admin can edit or delete all forms in database.
  13. User Profile area, user can upload a profile picture, change his password, view profile info like email, user id, role and joined date.
  14. Cron job to delete images from uploads/tmp folder when image age is greater than 1 hour. Cron runs every 1 hour, you need to run it node cron.js.

Building the Angular2 app

Run ng build

A new dist folder will be created with all files needed to run the Angular 2 app in front end.

If you want to make changes on the Angular2 app and auto-refresh the dist folder then run the following command in your terminal: ng build --watch

Running the server

Run npm start
If you want to make changes on the Server and auto refresh the back end code then run: nodemon npm start. If you don't have nodemon installed, run npm install nodemon -g. If you want to execute the cron job in order to clean up /uploads/tmp folder every 1 hour for files that their age is greater than 1 hour, run node cron.js.
