A Basic newsletter signup page that stores user's first name, last name and email into your Mail Chimp account. This project is based on the tutorial by Angela Yu on Udemy.

Install:

• Hyper Terminal as the main terminal
• Node.js (LTS recommended)
• git
• Heroku CLI

Documentation:

1. Download all the files in this repository(except "newsletter-page.png") into a folder and remember the folder's name and path.

   • Folder Name Example: Newsletter-Signup-Page.
   • Folder Path Example: yourName/Desktop/Newsletter-Signup-Page.
   • Note that some parts need to be changed in the app.js file

2. Create an account on Mail Chimp

   1. Click the bottom left from the dashboard to be directed to your profile.
   2. Click extras > API keys
   3. Click "Create a key".
      • Your API key would look like xxxxxxxxxxxxxxxxxxxx-us7
      • Note that the us7 is your Server Name/ID.
   4. Copy the API Key and Server Name in a safe place. Treat it like a password. (Note that if your API keys are exposed in public websites, Mail Chimp will automatically disable the API key)
   5. Click on "Audience" > "Manage Audience" > "Settings"
   6. Scroll down and copy the "Unique ID for audience" and save it somewhere.

3. In the app.js file:

   • Replace "YOUR_API_KEY" with the API key copied
   • Replace "YOUR_SERVER_NAME" with the server name (for example: us7)
   • Replace "YOUR_UNIQUE_LIST_ID" with the "Unique ID for audience" copied.

4. Create an account on Heroku

5. Open the Hyper terminal

   1. Change the directory to the folder you downloaded all the files using cd.

   2. For example: $cd Desktop/Newsletter-Signup-Page

   3. type in ls which means "list". This will list all the files available in the directory. Therefore, the files you downloaded should be the output.

      • For example: signup.html failure.html success.html public/ app.js procfile

   4. Other useful commands(Case sensitive. Spaces and spellings are important) :

      Description	Command
      Back to initial directory	cd ~
      Back to previous directory	cd ..
      Creating files	touch file_name
      Creating directory	mkdir directory_name
      Clear console (Will not delete commands, just keeping it tidy!)	clear
      Removing files	rm myfile

6. Make sure node.js and git are installed. Type node --version and git --version. If a version is shown, then you have node and git installed.

7. Make sure you are inside the directory. Then we will start by creating a package.json file by initializing npm.
   npm init

8. Press Enter for all the default fields.

9. Next we will be installing modules from npm. (express, mail chimp, and body-parser)

   • npm install express or npm i express (Both the same)

   • npm install @mailchimp/mailchimp_marketing

   • npm install body-parser

   • npm install -g nodemon (You can send your files on the local host with nodemon. The server restarts itself each time you make a change to your files)

     • In the hyper terminal type nodemon app.js
     • It should log "server running at port 3000"
     • Go to your browser and type localhost:3000 to see the page.
     • You can change the image of the signup page. (redirect the path to your image. Make sure it is in the images file in the public folder)
     • You can change the design. (I used bootstrap 4 for the design. Read the documentation and edit)

   • You should see this in your package.json file:

     "dependencies": {
        "@mailchimp/mailchimp_marketing": "^3.0.27",
        "body-parser": "^1.19.0",
        "express": "^4.17.1",
        }

10. Run the files on a local server to check if it works:

    • run nodemon app.js in Hyper terminal
    • In browser type localhost:3000
    • Fill in the fields.
    • Make sure you are directed to the success.html page after pressing sign up
      • if it is directed towards the failure.html page, check your API key, server name, and the unique list ID inserted earlier.
    • Go to your chimp mail account > audience > all contacts and see if your inputs are recorded there.

11. If successful, we will now use Heroku to host the signup page and it will be on the world wide web to be shared.

12. Run heroku --version if a version is not shown: run npm install -g heroku

13. Run heroku login and you will be directed to a page or required to enter your email and password.

14. Make sure you are still in the directory. ls to see all the files in the folder. You should have package.json files, HTML files, procfile, public folder, etc...

15. Run git init to initialise git

16. Run git add . add the files

17. Run git commit -m "Type anything here as a description" and all the files will be committed

18. Run heroku create

    • You should see a link https://Random-website-name.herokuapp.com/ in blue. Click it and you will see "Heroku | Welcome to your new app". This shows that you have succeeded.

19. Run git push heroku master to push your files to the heroku.

20. Refresh the page from the link just now or head to your heroku dashboard and click on "open app"

21. You should see the signup form.

22. Test the form by inputting and checking mail chimp again.

23. If the record appears on Mail Chimp, CONGRATULATIONS! You have successfully created the page and hosted it on the worldwide web.
