Example usage
const { Host } = require("@e-mc/core");
Host.loadSettings({
process: {
thread: { limit: 8 }
},
permission: {
disk_read: ["**/*"],
disk_write: ["/tmp/**"]
}
});
NOTE: @e-mc/core is mostly a collection of abstract base classes which cannot be instantiated. Host is more commonly called through @e-mc/file-manager.
