This is a simple shopping demo app, based on the same Angular/React/Vue.js examples in Essential Typescript by Adam Freeman:

• Front-end: (/src)
  • TypeScript
  • Component framework: Svelte 4
  • Application framework: SvelteKit 2
  • Static site generation: @sveltejs/adapter-static
  • CSS styles: Bootstrap
• Back-end: (/backend)
  • Golang
  • Static web server/web services: gin
  • SQLite driver: go-sqlite3
• Database: (/db)
  • SQLite

The project has a Dockerfile that creates a single container with multi-stage builds (image size less than 30 MB) and also supports to be opened in DevContainer/CodeSpace.

The Svelte app has the following routes:

SvelteKit has a feature to create "backend APIs", and I guess you would be able to call Node-based database packages from there if the production is built by @sveltejs/adapter-node and run in a Node environment. However the Golang server here is enough - and smaller too - so we don't really need to create duplicated APIs.

The backend creates two RESTful-like APIs:

Adam Freeman's original projects use json-server on an Express server as mock API services. I keep the spec of the services for the sake of demonstration. Right now, like all the original examples, the app only reads product lists and write order data. The Axios package used in the original examples is also replaced with fetch.

The purpose of project is an experiment to build a small, modern and self-contained full-stack monolithic application, but it is not meant to be a practical template for any real world applications. Error handlings are ignored in this project.

A similar version using Vue.js, Express, MongoDB and Docker Compose can be found here (no longer maintained).

For local development you'll need

• Git
• Node.js (for dev or production)
• Golang (for production)
• Docker (only required for generating the container)

If you are Windows user the go-sqlite3 package requires GCC to compile, which can be installed with MinGW (choose MinGW32-base, MinGW32-gcc-g++ and MinGW32-gcc-objc package, then add \MinGW\bin to $PATH). On Linux you can installing the package build-essential.

git clone https://github.com/alankrantas/svelteapp-typescript-go.git
cd svelteapp-typescript-go

Run the Svelte app in development mode. The app will not call any backend APIs, instead it returns mock product data and the returned order number is always 42.

npm run setup
npm run dev

The app will be open at http://localhost:3000.

Install dependencies, build both front-end and back-end apps and run the local server:

npm run setup-all
npm run build-all
npm run serve

The app would open at http://localhost:8080.

On Windows use npm run serve-win instead since NPM uses CMD to run bash scripts.

npm run upgrade-all

Use npm run upgrade to upgrade only the front-end dependencies.

npm run docker
npm run docker-run

The app would open at http://localhost:8080.

The database (./db/data.sqlite3) in this repo already contains the table products with 9 product records (which can be found in many Adam Freeman's books) and an empty table orders. You can use DB Browser for SQLite to read the database.

Here's the SQL statements to recreate them:

CREATE TABLE "products" (
	"id"	INTEGER NOT NULL UNIQUE,
	"name"	TEXT NOT NULL,
	"category"	TEXT NOT NULL,
	"description"	TEXT,
	"price"	REAL NOT NULL,
	PRIMARY KEY("id" AUTOINCREMENT)
);

CREATE TABLE "orders" (
	"id"	INTEGER NOT NULL,
	"product_id"	INTEGER NOT NULL,
	"quantity"	INTEGER NOT NULL
);

INSERT INTO "main"."products" (
	"id",
	"name",
	"category",
	"description",
	"price"
)
VALUES
	('1', 'Kayak', 'Watersports', 'A boat for one person', '275.0'),
	('2', 'Lifejacket', 'Watersports', 'Protective and fashionable', '48.95'),
	('3', 'Soccer Ball', 'Soccer', 'FIFA-approved size and weight', '19.5'),
	('4', 'Corner Flags', 'Soccer', 'Give your playing field a professional touch', '34.95'),
	('5', 'Stadium', 'Soccer', 'Flat-packed 35,000-seat stadium', '79500.0'),
	('6', 'Thinking Cap', 'Chess', 'Improve brain efficiency by 75%', '16.0'),
	('7', 'Unsteady Chair', 'Chess', 'Secretly give your opponent a disadvantage', '29.95'),
	('8', 'Human Chess Board', 'Chess', 'A fun game for the family', '75.0'),
	('9', 'Bling Bling King', 'Chess', 'Gold-plated, diamond-studded King', '1200.0');
