# Development Environment
## Prerequisite
Node is required for local development.
We recommend using a Node version manager ([nvm](https://github.com/nvm-sh/nvm) for example) to ensure a stable development environment is used.
Below are the required node / npm versions:
```sh
"node": ">18.13.0",
"npm": ">8.19.3"
```
## Installation
In your working directory, open terminal and paste the following commands:
```sh
cd Speedometer
npm install
```
## Run Development Server
1. In your terminal run:
```sh
npm run dev
```
## Local Server
Speedometer uses [http-server](https://github.com/http-party/http-server), which is a static HTTP server. Meaning it does not provide hot-reloading. By default, the dev script disables caching and local changes can be viewed by simply refreshing your browser window. Additional options of the http-server can be found [here](https://github.com/http-party/http-server#available-options).
