## How to install
|

|
|
||||||
|
```sh
|
||||||
|
npm install
|
||||||
|
```
|
||||||
|
|

|
## How to run in debug mode
|
||||||
|
|
||||||
|
```sh
|
||||||
|
# Builds the project and opens it in a new browser tab. Auto-reloads when the project changes.
|
||||||
|
npm start
|
||||||
|
```
|
||||||
|
|
||||||
|
## How to build in release mode
|
||||||
|
|
||||||
|
```sh
|
||||||
|
# Builds the project and places it into the `dist` folder.
|
||||||
|
npm run build
|
||||||
|
```
|
||||||
|
|
||||||
|
## What does each file do?
|
||||||
|
|
||||||
|
* `Cargo.toml` contains the standard Rust metadata. You put your Rust dependencies in here. You must change this file with your details (name, description, version, authors, categories)
|
||||||
|
|
||||||
|
* `package.json` contains the standard npm metadata. You put your JavaScript dependencies in here. You must change this file with your details (author, name, version)
|
||||||
|
|
||||||
|
* `webpack.config.js` contains the Webpack configuration. You shouldn't need to change this, unless you have very special needs.
|
||||||
|
|
||||||
|
* The `src` folder contains your Rust code.
