Summary

Functional permissions library to perform permission checking. Permissions are checked against the user permissions (an array of integers), that can be retrieved from core-admin-server. This library may be used on either servers or in the browser, anywhere where it can be require()ed.

Getting Started

Depedencies

  • Something that can require() (e.g. Node 6, RequireJS, webpack)

Usage

Has Permission

This checks if the user's permissions satisfies the the requested permission check.

const perm = require('functional-permissions-lib');
const adminPerms = perm.permissions.admin;
const userInfo = {
  permissions: [-8125, 31]
};

if (perm.util.hasAccessTo(adminPerms.org.create, userInfo.permissions)) {
  //allow user to perform action
} else {
  //deny the user
}

Has Any Permission

This checks if the user's permissions satisfies any of the requested permission checks.

const perm = require('functional-permissions-lib');
const adminPerms = perm.permissions.admin;
const userInfo = {
  permissions: [-8125, 31]
};

if (
  perm.util.hasAccessToAny(
    [adminPerms.org.create, adminPerms.group.create, adminPerms.role.create],
    userInfo.permissions
  )
) {
  //allow user to perform action
} else {
  //deny the user
}

Has All Permissions

This checks if the user's permissions satisfies all of the requested permission checks.

const perm = require('functional-permissions-lib');
const adminPerms = perm.permissions.admin;
const userInfo = {
  permissions: [-8125, 31]
};

if (
  perm.util.hasAccessToAll(
    [adminPerms.org.create, adminPerms.group.create, adminPerms.role.create],
    userInfo.permissions
  )
) {
  //allow user to perform action
} else {
  //deny the user
}

Get Mask From Permissions

This converts permission ids to a mask. Optionally, the caller can pass in a mask that will be used to add the permissions to.

const mask = getMaskFromPermissionIds([perm.permissions.admin]);

// OR;

const mask = getMaskFromPermissionIds([perm.permissions.admin], [-1526]);

Get Permissions From Mask

This converts a mask to permissions IDs.

const permissionIds = getPermissionIdsFromMask([-1526]);

Combine Permissions

This combines permissions.

const perm = require('functional-permissions-lib');
const adminPerms = perm.permissions.admin;
const cmsPerms = perm.permissions.csm;

const permissions = coombinePermissions(
  [adminPerms.org.create, adminPerms.group.create, adminPerms.role.create],
  [cmsPerms.media.create, cmsPerms.wrklows.create]
);

Go package

This repo an also be imported as a go package to help resolve user permissions in go projects.

import (
	permissions "github.com/veritone/functional-permissions-lib"
)

// sample usage
func SomethingUseful(...) {
	...
	masks := []int{2147483648, 2}

	// getting permission IDs from masks
	perms := GetPermissionIDsFromMasks(masks)
	...


	perms2 := []int{1, 13, 26, 62}

	// getting permission masks from IDs
	masks2 := GetMasksFromPermissionIDs(perms2)

	...

	// getting permission ID for a permission path
	permID, err := GetPermissionID("cms.media.read")
	defer permission.Free()
	...

}
