The example has been moved to https://github.com/stalniy/casl-examples/tree/master/packages/express-blog
Read CASL in Expressjs app for details.
CASL is an isomorphic authorization JavaScript library which restricts what resources a given user is allowed to access.
This is an example application which shows how integrate CASL in blog application. There are 3 entities:
- User
- Post
- Comment
Application uses passport-jwt for authentication.
Permission logic (i.e., abilities) are define in src/auth/abilities.js. Rules can be specified for authenticated and anonymous users, so potentially it's quite easy to give access anonymous users to leave comments in blog.
The main logic is built on top of modules (src/modules)
Note: refactored to use CASL 2.0. See @casl/ability and @casl/mongoose for details. Warning: this code is just an example and doesn't follow best practices everywhere (e.g. it stores passwords without hashing).
Note #2: in order to use with Vuex example switch to branch vue-api
git clone https://github.com/stalniy/casl-express-example.git
cd casl-express-example
npm install

"user": {
"....": "...."
}
}to create a post you send
{
"post": {
"....": "...."
}
}
