Plan to support domains?

[eternaltreesnow]

"Domain tenant" is useful in multi-group scenario. However, the API does not support multi-tenant at this stage, like lack of grouping policy, "can" function doesn't support "domain" param.
So I wonder whether the project plans to increase support for domain, or needs some PR support？

This is a demo for multi-tenant domain.

const casbin = require('casbin');
const data = {
    m: `
        [request_definition]
        r = sub, dom, obj, act
        [policy_definition]
        p = sub, dom, obj, act
        [role_definition]
        g = _, _, _
        g2 = _, _, _
        [policy_effect]
        e = some(where (p.eft == allow))
        [matchers]
        m = g(r.sub, p.sub, r.dom) && g2(r.obj, p.obj, r.dom) && r.dom == p.dom && r.act == p.act
    `,
    p: [
        ['p', 'admin', 'domain1', 'data1', 'read'],
        ['p', 'admin', 'domain1', 'data1', 'write'],
        ['p', 'admin', 'domain2', 'data2', 'read'],
        ['p', 'admin', 'domain2', 'data2', 'write'],
        ['p', 'data_group_admin', 'domain2', 'data_group', 'write'],
    ],
    g: [
        ['g', 'alice', 'admin', 'domain1'],
        ['g', 'alice', 'data_group_admin', 'domain2'],
        ['g2', 'data1', 'data_group', 'domain1'],
        ['g2', 'data2', 'data_group', 'domain2'],
    ],
};

const model = casbin.newModelFromString(data.m);
const enforcer = await casbin.newEnforcer(model);

const policies = data.p;
policies.forEach(async (policy) => {
    const policyResult = await enforcer.addNamedPolicy(...policy);
    console.log(`policy: ${policy.join(',')}, policyResult: ${policyResult}`);
});

const roles = data.g;
roles.forEach(async (role) => {
    const roleResult = await enforcer.addNamedGroupingPolicy(...role);
    console.log(`role: ${role.join(',')}, roleResult: ${roleResult}`);
})

const result = await enforcer.enforce('alice', 'domain1', 'data1', 'read');
console.log(`casbin result: ${result}`);

@eternaltreesnow are you using Casbin.js (this repo) or Node-Casbin (https://github.com/casbin/node-casbin) ?

[eternaltreesnow]

Yeah, I tried Casbin.js but found out that it doesn't support domain. This demo based on Node-Casbin is just to show a usage of domain.

Can you use https://github.com/casbin/node-casbin ? It also support browser.
