Full Stack Rust Web App - Twitter Clone

This is a programming exercise in Rust to create a simple Twitter clone using the tide web framework, async-std, http-types, tailwindcss, serde and mongodb. Since this is a full stack web application, it will also require a deployment setup and I’ve chosen to use Digital Ocean and the Digital Ocean App Platform to deploy with Docker Containers. We will make use of doctl when interacting with Digital Ocean to generate a simple spec.yml and make it so we can regularly update our project with continuous deployment through git.

Dependencies

To get started we are going to need the following dependencies (after initializing the project with cargo init).

[package]
name = "twitter-clone"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
async-std = { version = "1.12.0", features = ["attributes"] }
handlebars = "4.3.1"
serde = { version = "1.0.138", features = ["derive"] }
tide = { version = "0.17.0-beta.1", features = ["sessions", "h1-server", "cookies"] }
tide-flash = { version = "0.1.1-beta.1" }
env_logger = "0.9.0"
dotenv = "0.15.0"
time = { version = "0.2.6", default-features = false, features = ["std"] }
serde_json = "1.0.82"
async-redis-session = "0.2.2"
libreauth = { version = "0.15.0", features = ["oath-uri"] }
qrcode = "0.12.0"
async-trait = "0.1.56"
validator = { version = "0.15.0", features = ["derive"] }
uuid = { version = "1.1.2", features = ["serde", "v4"] }

This will give us the basics we need to build a simple web application using an async runtime (async-std), a web framework (tide), a templating library (handlebars), and JSON support (serde). A lot of the other dependencies here to are to fill in for logging, libreauth for two-factor totp authentication/token generation/validation, validator for serde style derive validation on forms via structs, uuid for unique id generation, qrcode to generate a qr code for the two-factor token uri, async-redis-session to support the redis based backend for session middleware.

Tasks

• Setup tide web application with basic routes
• Authenticated user/password manually
• Store users in memory for now
• Add support for totp qr code two factor authentication
• Add authentication middleware via request extensions
• Template responses to render to handlebar templates
• Flash style messages for any errors/logging with redirects
• Register users to memory store
• Validate forms with validator
• Use session middleware and session based authentication
• Add redis backend for session middleware
• [] Swap out backend for users to actual mongodb backend
• [] Refactor in memory lookups to use actual queries
