BACK-END (NodeJS + TypeScript)
- Nodemon: automatically restarting the node application when file changes in the directory are detected
- Express: production dependency for creating robusts APIs quickly with HTTP utility methods and middleware
- Ejs/Pug/Express-handlebars: software designed to combine templates with a data model to produce multiple pages that share the same look throughout the site. These are the views in an MVC project.
- Mysql2: mySQL to interact with the database
- Sequelize: Object-Relational Mapping Library that uses mysql2 to interact with the database running the queries behind the scenes
- Mongodb: MongoDB Driver to connect to MongoDB to handle the database engine (run noSQL databases for large scale applications)
- Mongoose: Object-Document Mapping Library that allow us to define models with which we then work and where all the queries are done behind the scenes
- Express-session: package to handle sessions, part of the official expressjs suite but not baked into expressjs itself
- Connect-mongodb-session: let our express session package store data in the database
- Bcryptjs: encrypting passwords
- Csurf: Node.js CSRF protection middleware. It generates a csrf token (string value we can embed into our forms/pages for every request that on the backend changes the users state, so anything that does something sensitive which we want to protect against).
- Connect-flash: flash is a special area of the session used for storing messages. Messages are written to the flash and cleared after being displayed to the user. The flash is typically used in combination with redirects, ensuring that the message is available to the next page that is to be rendered
- Nodemailer: send emails from inside nodejs
- Express-validator: validate forms on the server
- Multer: parses incoming requests handling files and being able to handle file requests as well or requests with mixed data, with text and file data.
- Pdfkit: pdf generator
- Stripe: suite of payment APIs that allows online payment processing
- Typescript: strongly typed programming language that builds on JavaScript
- Helmet: secure node express application: set headers to responses following best practices regarding attack patterns/security issues
- Compression: Nodejs express middleware that serves optimized assets
- Morgan: simplify logging request data
- Mocha: runs tests (executing the test code)
- Chai: asserts results (validating the test outcome)
- Sinon: creates Stubs, which is a replacement for the original function where we can easily restore the original set up, clearing stub functions.
- Jsonwebtoken: creates JSON web tokens for authentication on REST APIs. Creates data with optional signature and/or encryption whose payload holds JSON and is signed either using a private secret or a public/private key.
- Socket.io: (server) web sockets with a lot of convenience features around that protocol that make it very easy to set up a web socket channel with a client in the server and to use that channel.
- Socket.io-client: (web) socket.io for the client
- Graphql: required for defining the schema (definition of queries, mutations, etc) of the GraphQL service.
- Express-graphql: server to parse incoming requests
- Validator: validates inputs on the resolvers
