Rio

Rio is an opinated package manager built with Rust.

Under development

TODO list:

• fetch packages
  • loading
  • fallback install
• read packages and check cache
• cache management
  • OSX
  • Windows
• rio ls
• install script

Reasons

Packages by source

This also should allow the developer create a custom module namespace for the dependency if necessary.

 "dependencies": {
    "express": "github.com/expressjs/express/releases/tag/4.17.1", // 4.17.1
    "lodash": "github.com/lodash/lodash", // latest master
    "draft-js": "github.com/facebook/draft-js/tree/0.9-stable", // 0-9 stable branch

Install once

All the installed packages are shared across the projects by default using symlink (it reduces installed dependencies overall size).

If you need to install for ship into production you can use a specific flag with the install command: --disable-symlink.

Package Scoping

Let's say that you want to install express to a brand new project, so you run npm install express@4.17.1. Once that's done and then you want to check the node_modules scope, you're gonna see all the express dependencies in the runtime scope, for example:

$ node -e "console.log(require('cookie'))"
{ parse: [Function: parse], serialize: [Function: serialize] }

• This test was made using npm 6.14.2.

node_modules dependecies tree:

index.js

console.log(require('bytes'))
console.log(require('destroy'))
console.log(require('ee-first'))

$ node index.js
[Function: bytes] {
  format: [Function: format],
  parse: [Function: parse]
}
[Function: destroy]
[Function: first]

Rio is suitable to avoid this package scoping issue.

Benchmark

This test is using a lots of files (inspired by Benchmarks of JavaScript Package Managers)
