SvelteKit Dapp template

This project is provided by the IC-Academy to help you get started with development on the Internet Computer using SvelteKit, TypeScript and Vite.

This repository is meant to give SvelteKit developers an easy on-ramp to get started with developing decentralized applications (Dapps in short) for the Internet Computer blockchain.

Svelte version: 4.2.9
SvelteKit version: 2.5.0
@dfinity/agent: 1.0.0

What is this repository for?

This repository is made for my personal use, but feel free to use it as a template for your own projects.

Features

This templates includes two routes, a home page and a about page. The about page is a simple example of how to interact with the Internet Computer blockchain. It uses a simple store to store all queries.

It uses its own createActor function to create an actor for the Internet computer. This actor is implemented in the store and can therefore be used in all routes to interact with the Internet computer.

Getting started

Make sure you have node.js installed. Node.js version 16 or later is required.

Requirements: DFX + node.js

You can check your requirements by running the following commands in your terminal.

node --version
dfx --version

Tested with DFX version 0.19.0

You can install DFX by running the following command in your terminal.

sh -ci "$(curl -fsSL https://internetcomputer.org/install.sh)"

Fast Track

mkdir myapp && cd myapp

# terminal 1
dfx start --clean

# terminal 2
npx degit https://github.com/samlinux-development/ic-sveltekit.git
npm install

dfx deploy 
echo http://$(dfx canister id frontend).localhost:4943

Start and stop the local replica

Open a new terminal window in the project directory, and run the following command to start the local replica. The replica will not start unless dfx.json exists in the current directory.

dfx start --clean --background

When you're done with development, or you're switching to a different dfx project, running

dfx stop

from the project directory will stop the local replica.

Build & run the dapp

To build and deploy the project locally run

dfx deploy

When the process completes you'll have a frontend canister running locally. To find the frontend canister's ID, run

dfx canister id frontend

It will output something similar to rno2w-sqaaa-aaaaa-aaacq-cai. Copy this ID and open it in the browser using http://<canister ID>.localhost:4943, eg. http://rno2w-sqaaa-aaaaa-aaacq-cai.localhost:4943.

Local development

You can serve the frontend in development mode like you normally develop an app using the command. But first, make sure your run dfx deploy to create the .env file and all decalarations.

npm run dev

Deploying to the playground

To test your dApp under the Internet Computer's environment, you can deploy it to the Motoko Playground.

dfx deploy --playground
