Getting started

To get this project up and running locally:

  1. Clone this repo
  2. Run npm install to install all of the required dependencies.
  3. Install MongoDB Community Edition on you local machine. Instructions can be found here.
  4. Create a db called tiemendo & tiemendo_test
> use tiemendo
> db.testCollection.insertOne({ x: 1 });
> use tiemendo_test
> db.testCollection.insertOne({ x: 1 });
  1. Create a .env file in the root of the project with the following environment variables:
DB_CONNECTION=mongodb://localhost:27017/tiemendo
DB_CONNECTION_TEST=mongodb://localhost:27017/tiemendo_test
JWT_SECRET=<generated string>
  • You can generate a token secret using python: python >>> import random >>> ''.join([random.SystemRandom().choice('abcdefghijklmnopqrstuvwxyz0123456789!@#\$%^&amp;*(-_=+)') for i in range(50)]);
  1. npm run dev to start the local server
  2. npm test to start server using testing environment

Backend Frameworks

Our rationale in choosing the frameworks we used:

Express

  • We agreed to use Express as it is a familiar web server framework to what we knew that is extremely easy to use.
  • It is modular and has great authentication, cookies, and sessions libraries.

NodeJS

  • Excellent third-party library support through NPM
  • It has a large and robust open-source community and great support on Stack Overflow and other platforms for trouble-shooting.

MongoDB

  • Would give greater exposure to the NoSQL database paradigm - perfectly complementing our SQL background during our Lambda School curriculum.
  • Greater freedom in schema design during prototyping and ideation. Also a greater familiarity with JSON-like object
  • Greater scalability with sharding and load-balancing with future product cycles and user growth.
  • First-party, pre-installed servers available for free through MongoDB.

Environment Variables

In order for the app to function correctly, the user must set up their own environment variables.

Create a .env file that includes the following:

  • DB_CONNECTION - URL for MongoDB connection string in a development/production environment.
  • DB_CONNECTION_TEST - URL for MongoDB connection string in a testing environment.
  • NODE_ENV - for setting application environment. Set to development by default. Should be set to production when in a staging or production environment.
  • JWT_SECRET - for signing JSON web tokens. You can generate this by using a python shell and running:
import random''.join([random.SystemRandom().choice('abcdefghijklmnopqrstuvwxyz0123456789!@#\$%^&amp;*(-_=+)') for i in range(50)])

You can also check .env.example to know all required environment variables.

Testing

Tests are setup as independently as possible (they do not rely on other tests to pass). General setup of tests is in ./tests/testsSetup.js file. The only shared variable that is used in tests is the JWT token stored as token or staffToken generated by login tests.

Before each test, all collections in the database are deleted and new seed documents are entered. After all tests are done, collections are deleted and then dropped.

To run the tests when developing, run:

npm run dev-test

It will run tests in "watch" mode and stops running tests on first failed test (-b).

To run tests as in CI and with coverage, run:

npm run test
