Inspired by Hackathon Starter, this project is a more simplified boilerplate application with some basic examples of user authentication with Passport and authorization via an ACL. Authenticated user data is persisted in session cookies and on a MongoDB instance.
This project was originally presented at the Front End PDX meetup. If you'd like to view the slides presented at the meetup, they're available on slides.com.
This application has been designed to use the free tiers of these services to get a live development environment up and running with minimal effort. In order to deploy this application as-is, you will need accounts from these services:
- Heroku - hosts the application.
- SendGrid - used for email notifications. Look for the free tier towards the bottom of the signup page.
- mLab - hosts the Mongo database. This one is optional as you can add an mLab database directly to your Heroku instance without an mLab account. However, if you'd like to have separate databases for your local development and Heroku environments, you will need to create an mLab account.
- Fork this project to your own GitHub account.
- Sign up for or log into a Heroku account and create a new app.
- On your app, change the Deployment Method on the Deploy tab to "GitHub."
- Search for your forked project and connect your repository.
- On the Resources tab, search for "mLab" under Add-ons. Add the mLab add-on, choosing the free sandbox plan. This will automatically add the environment variable for
MONGODB_URI. - Create an API key for your SendGrid account. Make sure it has full email send capabilities; it doesn't need anything else.
- On the Settings tab, add the necessary environment variables.
- On the Deploy tab, perform a manual deployment of the master branch. Once the deployment is complete, you should be able to open your app.
- Clone the repository locally.
- If you don't have Node installed, install it.
- In a console window, navigate to the repository directory and install the dependencies with
npm install. - Create a new file at the root of the repository directory with the name
.env. Add the necessary environment variables. - In your console window, execute
npm startto launch the application. It will be viewable in your browser at http://localhost:3000/.
The below environment variables are needed to get the application up and running.
ACL_COLLECTION_PREFIX- the prefix for the ACL data collection in the Mongo database.LOGIN_ATTEMPTS_LOCKOUT_HOURS- the amount of time, in hours, that a user is locked out of their account due to exceeding the maximum number of login attempts.MAX_LOGIN_ATTEMPTS- the maximum number of login attempts a user can perform before being locked out.MINIMUM_PASSWORD_LENGTH- the minimum length of user passwords.MONGODB_URI- this only needs to be added manually if you are A) working locally or B) using your own mLab instance that you didn't provision through Heroku.PASSWORD_HASH_ROUNDS- the number of rounds for bcrypt to apply its hashing algorithm. The higher the rounds, the more secure the password is, but the more computing power is needed to hash passwords. Choose a number that best balances security and performance.PASSWORD_RESET_TIME_LIMIT_IN_HOURS- the amount of time a user has to reset their password if they go through the "Forgot Password" process.SEND_EMAILS_FROM- the email address from which you will send notification emails.SENDGRID_API_KEY- the API key you just created for your SendGrid account.SESSION_SECRET- the secret key used to encode session data.TZ- the timezone of the server. This is used to calculate times that are sent to users in emails regarding login activity. Use this list on Wikipedia for reference using the TZ column.
