  Pre-requisites for DevelopmentPre-requisitesfor Development  Exposure to Angular and JavaScript JWT (JSON Web Tokens for Authentication https://jwt.io/  Node.js and npm (Node Package Manager) installed on your machine https://github.com/nodejs/node/wiki  General understanding of ES6 This includes new syntax and features for JavaScript, Ex: import/export, class, let, const, arrow functions, etc. https://ponyfoo.com/articles/es6  Knowledge of component-based development and web components Components allow for a clear separation of concern and allow you to build highly reusable code  Understanding of Production Deployment in Cloud Ex: Cloud Foundry or Docker (Containers)

  AuthenticationAuthentication  Crypto (https://www.npmjs.com/package/cryptojs) o Provides standard and secure cryptographic algorithms for NodeJS o Supports MD5, SHA-1, SHA-256, SHA-512, RC4, Rabbit, AES, DES, PBKDF2, HMAC, OFB, CFB, CTR, CBC, Base64  To Store Password o Generate a long random salt using randomBytes(). o Prepend the salt to the password and hash it with a standard password hashing function like Argon2, bcrypt, scrypt, or PBKDF2. o Save both the salt and the hash in the user's database record  What is JSON Web Token? https://jwt.io/introduction/ JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA
