Dependency injection

// Class object injection
@Component()
export class A {

}

@Component()
export class B {
    @Autowired()
    protected a: A;
}

// Configuration property injection
@Component()
export class C {
    @Value('foo') // Support EL expression syntax, such as @Value('obj.xxx'), @Value('arr[1]') etc.
    protected foo: string;
}

Database operations

import { Controller, Get, Param, Delete, Put, Post, Body } from '@celljs/mvc/lib/node';
import { Transactional, OrmContext } from '@celljs/typeorm/lib/node';
import { User } from './entity';
@Controller('users')
export class UserController {
    
    @Get()
    @Transactional({ readOnly: true })
    list(): Promise<User[]> {
        const repo = OrmContext.getRepository(User);
        return repo.find();
    }
    @Get(':id')
    @Transactional({ readOnly: true })
    get(@Param('id') id: number): Promise<User | undefined> {
        const repo = OrmContext.getRepository(User);
        return repo.findOne(id);
    }
    @Delete(':id')
    @Transactional()
    async remove(@Param('id') id: number): Promise<void> {
        const repo = OrmContext.getRepository(User);
        await repo.delete(id);
    }
    @Put()
    @Transactional()
    async modify(@Body() user: User): Promise<void> {
        const repo = OrmContext.getRepository(User);
        await repo.update(user.id, user);
    }
    @Post()
    @Transactional()
    create(@Body() user: User): Promise<User> {
        const repo = OrmContext.getRepository(User);
        return repo.save(user);
    }
}
