4: Motoko quickstart

Overview

This at-a-glance cheat sheet summarizes the steps to follow for quick reference.

Prerequisites

Before getting started, assure you have set up your developer environment according to the instructions in the developer environment guide.

Creating a new project

Open a terminal window on your local computer, if you don’t already have one open.

Create a new project and change to the project directory.

Use `dfx new [project_name]` to create a new project:

```
dfx new hello_world
```

You will be prompted to select a language that your backend canister will use:

```
? Select a backend language: ›
❯ Motoko
Rust
TypeScript (Azle)
Python (Kybra)
```

Then, select a frontend framework for your frontend canister. In this example:

```
? Select a frontend framework: ›
SvelteKit
React
Vue
❯ Vanilla JS
No JS template
No frontend canister
```

Lastly, you can include extra features to be added to your project:

```
? Add extra features (space to select, enter to confirm) ›
⬚ Internet Identity
⬚ Bitcoin (Regtest)
⬚ Frontend tests
```

Editing the default files

Edit the src/<project_name>_backend files to define your service or application.

Edit the src/<project_name>_frontend files with HTML, JavaScript, and CSS that provides the frontend for your service or application.

Starting the deployment environment

Start the Internet Computer for local development or check your connection to the Internet Computer for network deployment:

Register, build, and deploy locally or on the mainnet

To deploy locally, use the command:

dfx deploy

For deploying to the mainnet, use: --network ic.

dfx deploy --network <network>

View your service or application in a browser, using the URLS in the output of the dfx deploy command:
