Introduction

This library provides a simple way to generate a Postman collection for your NestJS Rest API app. With this library, you can easily export your API endpoints as a Postman collection, allowing you to test your API with Postman.

Installation

#Using NPM
npm i nest-postman

#Using YARN
yarn i nest-postman

Getting Started

To register PostmanModule with your app, import the module inside AppModule (your root module).

Static Registration

PostmanModule is added to global scope.

import { Module } from '@nestjs/common';
import { PostmanModule } from 'nest-postman'

@Module({
  imports: [
    PostmanModule.register({
      collectionName: process.env.APP_NAME || 'NestJS App',
      url: process.env.APP_URL || `http://localhost:${process.env.APP_PORT}/`,
      prefix: 'v1',
      filePath: '',
      description: 'This is my collection.'
    })
  ],
  controllers: [],
  providers: [],
})
export class AppModule { }

Recommended Way

Use ConfigModule provided by NestJS to load configurations. To learn about ConfigModule, click here.

#1. Create postman.ts file

import { PostmanOptions } from 'nest-postman/interfaces';
import { registerAs } from '@nestjs/config';
export default registerAs(
  'postman',
  () =>
    ({
      collectionName: process.env.APP_NAME || 'NestJS App',
      url: process.env.APP_URL || `http://localhost:${process.env.APP_PORT}/`,
      prefix: 'v1',
      filePath: '',
      description: 'This is my collection.',
    } as PostmanOptions),
);

#2. Register ConfigModule

import { Module } from "@nestjs/common";
import postman from "@config/fileystem";
import { ConfigModule } from "@nestjs/config";

@Module({
  imports: [
    ConfigModule.forRoot({
      isGlobal: true,
      expandVariables: true,
      load: [postman],
    }),
  ],
  controllers: [],
  providers: [],
})
export class AppModule {}

#3. Register Async StorageModule Add following snippet to the imports array. ConfigService is importable from @nestjs/config module.

 PostmanModule.registerAsync({
      imports: [ConfigModule],
      useFactory: (config: ConfigService) => config.get('postman'),
      inject: [ConfigService],
    })

Usage

As soon as you run your app, there will be a file created with name collection.json in your project directory. Use that file to import in your postman application and HOLA, your postman collection is ready for use.
