AlsoCan is an authorization library. It's a replacement for CanCan with additonal features:
Features:
- Export all permissions of a given user to load them up on the front end
- Support for explicity deny
- Rich debugging output to show exactly why an action was allowed or denied
- Wildcard actions
- Zero dependencies
Usage
npm install alsocan
const AlsoCan = require('./alsoCan');
const alsoCan = new AlsoCan({
targetCompare: (instance, model) => instance instanceof model,
userCompare: (user, role) => user.role === role,
// Will print debug info to the console if truthy
debug: process.env.DEBUG_AUTHORIZATION,
defaultUser: user => user || { name: 'general public', permission: 'public' }
});
class Posts {};
const isSameOrg = (user, target, ctx, action) => user.organisationId === target.organisationId;
const isOwner = (user, target, ctx, action) => user.id === target.userId;
allow('ADMIN', ['manage'], Posts, isSameOrg);
allow('USER', ['edit*'], Posts, isOwner);
// Authorize access to a record, throws if not allowed
alsoCan.authorize(user, 'edit', record, ctx);
// Returns true if the user can perform the action
const can = alsoCan.can(user, 'edit', record, ctx);
