Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including browser-acl. Try it out:
const { default: Acl } = require('browser-acl')
const acl = new Acl()
class User {
constructor({ id, name, role = 'user' }) {
this.id = id
this.name = name
this.role = role
}
isModerator() {
return this.role === 'moderator' || this.role === 'admin'
}
isAdmin() {
return this.role === 'admin'
}
}
class Post {
constructor({ userId, title }) {
this.title = title
this.userId = userId
}
}
class Comment {
constructor({ userId, body }) {
this.body = body
this.userId = userId
}
}
class CommentPolicy {
beforeAll(_, user) {
if (user.isAdmin()) {
return true
}
}
edit(user, comment) {
return comment.userId === user.id
}
moderate(user, _) {
return user.isModerator()
}
}
acl.rule('view', Post)
acl.rule('moderate', Post, user => user.isModerator())
acl.rule(['edit', 'delete'], Post, (user, post) => post.userId === user.id)
acl.rule('purgeInactive', user => user.isAdmin())
acl.policy(CommentPolicy, Comment)
const admin = new User({ id: 1, name: 'Admin', role: 'admin' })
const moderator = new User({ id: 2, name: 'Moderator', role: 'moderator' })
const user1 = new User({ id: 3, name: 'User 1', role: 'user' })
const user2 = new User({ id: 4, name: 'User 2', role: 'user' })
const post1 = new Post({ userId: 3, title: 'Post 1' })
const comment1 = new Comment({ userId: 3, body: 'Hmmm...' })
console.log('User 1 can edit post 1?', acl.can(user1, 'edit', post1))
console.log('User 2 can edit post 1?', acl.can(user2, 'edit', post1))
console.log('Moderator can edit post 1?', acl.can(moderator, 'edit', post1))
console.log(
'Moderator can moderate post 1?',
acl.can(moderator, 'moderate', post1),
)
console.log('Admin can edit comment 1?', acl.can(admin, 'edit', comment1))
console.log('User 2 can edit comment 1?', acl.can(user2, 'edit', comment1))
