Install a node dependency tree on disk.

The installation is done using a flat folder structure where packages are connected with symlinks. This package is meant to be used as a component of a package manager.

Features:

• Install packages in a flat structure.
• Install bin scripts.
• Support package names with a namespace.
• Multiple packages can have the same name (usefull to support various version or conflicting peerDependencies).

Usage:

const { installLocalStore } = require("local-package-store");

const location = "<path to an empty folder>";
const dependencyGraph = {
    nodes: [{
        key: "1",
        location: "location where the uninstalled package is on disk"
    },
    {
        key: "2",
        location: "location where the uninstalled package is on disk"
    }],
    links: [{ source: "1", target: "2"}]
}

installLocalStore(
    dependencyGraph,
    location
).then(() => {
    /* Installation is done */
})

The inputs are:

• The dependency graph of packages. Contains a list of packages and a list of dependencies between them.
• The location of a store. This is where the packages will be installed on disk.
