Full stack application using Rust's Axum framework & Askama templating language with user auth management (JWT) + CRUD to a SQLite database (To Do List) and HTMX in the frontend.
🤦 Yes, just another to-do application, but to try something new you have to start somewhere ¯\_(ツ)_/¯.
Note
This application is an improved clone of this repository of mine (go-echo-templ-htmx), but made in Rust.
In the implementation of this application we have used the following technologies:
- ✅ Bootstrapping: Rust programming language (v1.77.0)
- ✅ Backend Framework: Axum v0.7.5
- ✅ Database: Sqlite
- ✅ Templating Language: Askama v0.12.1
- ✅ Styling: TailwindCSS + DaisyUI
- ✅ Frontend interactivity: </>Htmx + _Hyperscript
Note
The use of </>htmx allows behavior similar to that of a SPA, without page reloads when switching from one route to another or when making requests (via AJAX) to the backend. Likewise, the _hyperscript library allows you to add some dynamic features to the frontend in a very easy way.
Register and Todo List pages with error & success alerts, respectively, and task creation modal dialog:
Modal Task Update Dialog, Confirm Dialog (with con SweetAlert2), and unknown path or resource not found page (Error 404):
Error page 401 (Status Unauthorized), task update modal dialog showing that the resource is no longer in the DB and Error page 400 (Bad Request) which indicates that the creation/update of the task needs at least the title:
Besides the obvious prerequisite of having Rust on your machine, you must have cargo watch installed for hot reloading when editing code.
On the other hand, since we use a SQL database (Sqlite3), you must have SQLX-CLI installed which will allow you to build the database and perform migrations. You can install it (with the necessary feature for Sqlite) with the command:
$ cargo install sqlx-cli -F sqlite
Next, you can build the database and perform the migrations that generate the users and todos tables. Make sure that the migrations folder is present (which contains the necessary migrations) and the .env file that explains the DATABASE_URL environment variable. To do this, you must execute these commands:
$ sqlx database create # generates the DB
$ sqlx migrate run # generates migrations. (`sqlx migrate revert` to reverse migrations)
Before compiling the binary, you will need to regenerate the CSS. First, you have to install the dependencies required by Tailwind CSS and daisyUI (you have to have Node.js installed on your system) and then run the regeneration of the main.css file. To do this, apply the following commands:
$ cd tailwind && npm i
$ npm run build-css-prod
Build the binary file and run it with the command (in proyect root):
$ cargo build --release && ./target/release/rust-axum-askama-htmx # Ctrl + C to stop the application
If what you want is to edit the code, it will be more convenient to activate hot reload:
$ cargo watch -x run # files/folders contained in .gitignore will be ignored
Note
If you are editing the code and you are logged into the application in the browser, when the hot reload occurs when saving, since some global flags (such as from_protected and time_zone) are stored in a session (in memory) they will be lost and you will need to log in again.
If you also want to modify the CSS of the templates, it will be useful to activate the watch mode of Tailwindcss, executing the command inside the tailwind folder (you need to have Node.js installed):
$ npm run watch-css # minify for production: npm run build-css-prod
