TypeORM Adapter is the [TypeORM](https://github.com/typeorm/typeorm) adapter for [Node-Casbin](https://github.com/casbin/node-casbin). With this library, Node-Casbin can load policy from TypeORM supported database or save policy to it.
Based on [Officially Supported Databases](http://typeorm.io), the current supported databases are:
- MySQL
- PostgreSQL
- MariaDB
- SQLite
- MS SQL Server
- Oracle
- WebSQL
- MongoDB
You may find other 3rd-party supported DBs in TypeORM website or other places.
## Installation
npm install typeorm-adapter
## Simple Example
```typescript
import { newEnforcer } from 'casbin';
import TypeORMAdapter from 'typeorm-adapter';
async function myFunction() {
// Initialize a TypeORM adapter and use it in a Node-Casbin enforcer:
// The adapter can not automatically create database.
// But the adapter will automatically create and use the table named "casbin_rule".
// I think ORM should not automatically create databases.
const a = await TypeORMAdapter.newAdapter({
type: 'mysql',
host: 'localhost',
port: 3306,
username: 'root',
password: '',
database: 'casbin',
});
const e = await newEnforcer('examples/rbac_model.conf', a);
// Load the policy from DB.
await e.loadPolicy();
// Check the permission.
await e.enforce('alice', 'data1', 'read');
// Modify the policy.
// await e.addPolicy(...);
// await e.removePolicy(...);
// Save the policy back to DB.
await e.savePolicy();
}
```
## Simple Filter Example
```typescript
import { newEnforcer } from 'casbin';
import TypeORMAdapter from 'typeorm-adapter';
async function myFunction() {
// Initialize a TypeORM adapter and use it in a Node-Casbin enforcer:
// The adapter can not automatically create database.
// But the adapter will automatically create and use the table named "casbin_rule".
// I think ORM should not automatically create databases.
const a = await TypeORMAdapter.newAdapter({
type: 'mysql',
host: 'localhost',
port: 3306,
username: 'root',
password: '',
database: 'casbin',
});
const e = await newEnforcer('examples/rbac_model.conf', a);
// Load the filtered policy from DB.
await e.loadFilteredPolicy({
'ptype': 'p',
'v0': 'alice'
});
// Check the permission.
await e.enforce('alice', 'data1', 'read');
// Modify the policy.
// await e.addPolicy(...);
// await e.removePolicy(...);
// Save the policy back to DB.
await e.savePolicy();
}
```
## Custom Entity Example
Use a custom entity that matches the CasbinRule or MongoCasbinRule in order to add additional fields or metadata to the entity.
```typescript
import { newEnforcer } from 'casbin';
import {
CreateDateColumn,
UpdateDateColumn,
} from 'typeorm';
import TypeORMAdapter from 'typeorm-adapter';
@Entity('custom_rule')
class CustomCasbinRule extends CasbinRule {
@CreateDateColumn()
createdDate: Date;
@UpdateDateColumn()
updatedDate: Date;
}
async function myFunction() {
// Initialize a TypeORM adapter and use it in a Node-Casbin enforcer:
// The adapter can not automatically create database.
// But the adapter will automatically create and use the table named "casbin_rule".
// I think ORM should not automatically create databases.
const a = await TypeORMAdapter.newAdapter({
type: 'mysql',
host: 'localhost',
port: 3306,
username: 'root',
password: '',
database: 'casbin',
},
{
customCasbinRuleEntity: CustomCasbinRule,
},
);
const e = await newEnforcer('examples/rbac_model.conf', a);
// Load the filtered policy from DB.
await e.loadFilteredPolicy({
'ptype': 'p',
'v0': 'alice'
});
// Check the permission.
await e.enforce('alice', 'data1', 'read');
// Modify the policy.
// await e.addPolicy(...);
// await e.removePolicy(...);
// Save the policy back to DB.
await e.savePolicy();
}
```
## Custom Database Table Name Example
If you want to use a custom table name for the casbin rules, you need to:
Create a custom entity class that inherits from CasbinRule and uses the @Entity decorator with your table name.
Pass the custom entity class to the entities array of the data source constructor.
Pass the custom entity class to the customCasbinRuleEntity option of the typeorm-adapter constructor.
```typescript
import { newEnforcer } from 'casbin';
import {
CreateDateColumn,
UpdateDateColumn,
} from 'typeorm';
import TypeORMAdapter from 'typeorm-adapter';
@Entity('custom_rule')
class CustomCasbinRule extends CasbinRule {
@CreateDateColumn()
createdDate: Date;
@UpdateDateColumn()
updatedDate: Date;
}
async function myFunction() {
// Initialize a TypeORM adapter and use it in a Node-Casbin enforcer:
// The adapter can not automatically create database.
// But the adapter will automatically create and use the table named "casbin_rule".
// I think ORM should not automatically create databases.
const datasource = new DataSource({
type: 'mysql',
host: 'localhost',
port: 3306,
username: 'root',
password: '',
database: 'casbin',
entities: [CustomCasbinRule],
synchronize: true,
});
const a = await TypeORMAdapter.newAdapter(
{ connection: datasource },
{
customCasbinRuleEntity: CustomCasbinRule,
},
);
const e = await newEnforcer('examples/rbac_model.conf', a);
// Load the filtered policy from DB.
await e.loadFilteredPolicy({
'ptype': 'p',
'v0': 'alice'
});
// Check the permission.
await e.enforce('alice', 'data1', 'read');
// Modify the policy.
// await e.addPolicy(...);
// await e.removePolicy(...);
// Save the policy back to DB.
await e.savePolicy();
}
```
