## What you get
- Converts variable port numbers into memorable named addresses
- Provides automatic HTTPS and HTTP/2 support
- Creates separate URLs for each package in monorepo structures

## Installation
**General installation**

```
npm install -g portless
```

**Project-based setup**

```
npm install -D portless
```


## Running it
**Start the application with a named URL**

```
portless myapp next dev
```


## If you don't write code
I want the services running in my local development environment to use persistent addresses with the .localhost extension instead of port numbers. Run my project using the Portless tool and enable me to access my services via identifiable addresses like https://myapp.localhost.
