locport

• Standardizes keeping track of local development ports.
• See which ports are listening.
• Automatically assign unused ports.
• See conflicts.
• Proxy and daemon free.

A project can define within it's root, the .localhost file, that lists local hosts with ports that the project uses.

Format of this file is a simple list of <host>:<port> separated by newlines. For example:

hello.localhost:3001
another.service.localhost:3002

A single project can have multiple addresses associated to it.

To add the project to locport, simply locport index [PATH1] [PATH2]. Now you can overview hosts and ports with locport and easily discover conflicts across any number of projects.

You can also add projects recursively, like so: locport index ~/projects -r. This will look for directories that contain .localhost file and indexes those.

Ruby is required.

gem install locport

You've got several options to create or add to .localhost file, from within your project directory:

# Creates .localhost file in the current directory, with randomly assigned unused port,
# and hostname based on the current directory name suffixed with .localhost
locport add

# Adding a custom hostname and letting locport find a port
locport add myapp.localhost

# Example with a user specified port
locport add myapp.localhost:30000

All of the above action ensure the project is also indexed by locport.

locport
# OR
locport list

If any conflicts are detected, they will be displayed and program exits with error code 1.

# Add specific projects that contain .localhost file
locport index ~/projects/a ~/projects/b

# Recursively find and index .localhost files
locport index -r ~/projects

You can view the location of the projects index, which is a single text file, containing project paths, separated by a newline.
