Readme
Nestjs wrapper for Node-Idempotency.
Implements @node-idempotency/core
as a nestjs interceptor.
Internet requests are unpredictable; clients/proxies may send duplicate or concurrent requests due to retries or network issues. To ensure smooth operation, servers must process each request only once. This package detects and handles duplicates, preventing issues like double charging the customer. It's:
npm i @node-idempotency/nestjs
import { NodeIdempotencyModule } from '@node-idempotency/nestjs';
@Module({
imports: [
NodeIdempotencyModule.forRootAsync({
storage: {
adapter: StorageAdapterEnum.memory, // or 'redis'
options: /* adapter options */,
},
...idempotencyOptions, // additional idempotency options
}),
],
})
export class AppModule {}
storage.adapter
can either be memory
, redis
or an instance of Storage
interface.storage.options
are options to the storage client, required for redis
, is client options of redis client.idempotencyOptions
are the IdempotencyOptions
passed to @node-idempotency/core/Idempotency
import { Controller, Get, Post, HttpCode, Body } from "@nestjs/common";
import { Idempotent } from "@node-idempotency/nestjs";
@Controller()
@Idempotent({ ...idempotencyOptions }) // Override module-level options
export class CounterController {
counter = 0;
@Get()
getNumber(): number {
return this.counter++;
}
@Post()
@HttpCode(201)
async addNumber(@Body() { number }: { number: number }): Promise<number> {
this.counter += number;
return this.counter;
}
}
import { Controller, Get, Post, HttpCode, Body } from "@nestjs/common";
import { Idempotent } from "@node-idempotency/nestjs";
@Controller()
export class CounterController {
counter = 0;
@Idempotent({ ...idempotencyOptions }) // Override module-level options
@Get()
getNumber(): number {
return this.counter++;
}
@Post()
@HttpCode(201)
async addNumber(@Body() { number }: { number: number }): Promise<number> {
this.counter += number;
return this.counter;
}
}
Library also exports the interceptor, you can use it like you would use any nestjs interceptors(ex: registering globaly)
import { NodeIdempotencyInterceptor } from "@node-idempotency/nestjs";
