@nestjs-kitchen/connextion-presto v2.0.6

@nestjs-kitchen/connextion-presto

A flexible module to provide presto-client interface in NextJS.

Install

$ npm install --save @nestjs-kitchen/connextion @nestjs-kitchen/connextion-presto presto-client @types/presto-client

Usage

Apply PrestoModule

1. Export module, service & decorator.

   export const { Presto, PrestoModule } = definePresto();
   export type Presto = InstanceType<typeof Presto>;

2. Register presto connection instance with options.

   @Module({
     imports: [
       // By default it will register a connection instance called `default`.
       PrestoModule.register({
         // default's options...
       })
     ],
     providers: [SampleService]
   })
   export class SampleModule {} 

3. Inject Presto service.

   import { Presto } from './file-that-exported-presto';
   
   @Injectable()
   class SampleService {
     constructor(
       private readonly presto: Presto,
     ) {}
   
     async sampleMethod() {
       const result1 = await this.presto.default.execute({ query: `select 1=1;` });
     }
   }

Register multiple presto instances

1. Define presto connection instance names and export module, service & decorator.

   e.g.: instance_1,instance_2.

   export const { Presto, PrestoModule } = definePresto<'instance_1' | 'instance_2'>();
   export type Presto = InstanceType<typeof Presto>;

2. Register presto connection instances with options.

   @Module({
     imports: [
       PrestoModule.register({
         connections: [
           {
             name: 'instance1',
             // instance_1's options...
           },
           {
             name: 'instance2',
             // instance_2's options...
           }
         ]
       })
     ],
     providers: [SampleService]
   })
   export class SampleModule {} 

3. Inject Presto service.

   import { Presto } from './file-that-exported-presto';
   
   @Injectable()
   class SampleService {
     constructor(
       private readonly presto: Presto,
     ) {}
   
     async sampleMethod() {
       const result1 = await this.presto.instance1.execute({ query: `select 1=1;` });
     }
   }
