# ns-paystack

The wrapper provides a convenient way to integrate Paystack payment functionality into your NestJS applications.

## Installation

```shell
npm install @bp-devtools/ns-paystack
```

or

```shell
yarn add @bp-devtools/ns-paystack
```

## Configuration

To use the ns-paystack, you need to provide your Paystack API key. You can obtain the API key from the Paystack
dashboard. Once you have the API key, you can configure the wrapper in your NestJS application.

```typescript
import { Module } from '@nestjs/common';

import { NsPaystackModule } from '@bp-devtools/ns-paystack';
import { ConfigService } from '@nestjs/config';
import { TransactionsService } from './transactions/services/transactions.service';
import { TransactionController } from './transactions/controllers/transaction.controller';

@Module({
  imports: [
    NsPaystackModule.register({
      secretKey: 'PAYSTACK_SECRET_KEY'
    })
  ],
})
export class AppModule {
}
```

### Using async registration to access environment variables

```typescript
import { Module } from '@nestjs/common';

import { NsPaystackModule } from '@bp-devtools/ns-paystack';
import { ConfigService } from '@nestjs/config';

@Module({
  imports: [
    NsPaystackModule.registerAsync({
      useFactory: (configService: ConfigService) => {
        return {
          secretKey: configService.get('PAYSTACK_SECRET_KEY')
        };
      },
      inject: [ConfigService]
    })
  ]
})
export class AppModule {
}
```

### Usage

#### In Service

```typescript
import { Injectable } from '@nestjs/common';
import {
  PsTransactionsService,
  PsInitializeTransactionRequestModel,
  PsInitializeTransactionResponseModel,
} from '@bp-devtools/ns-paystack';

@Injectable()
export class TransactionsService {
  constructor(
    private readonly psTransactionsService: PsTransactionsService
  ) {
  }

  initializeTransaction(
    payload: PsInitializeTransactionRequestModel
  ): Promise<PsInitializeTransactionResponseModel> {
    return this.psTransactionsService.initializeTransaction(payload);
  }
}
```

#### In Controller

```typescript
import { Body, Controller, Post } from '@nestjs/common';
import {
  PsFetchTransactionResponseModel,
  PsInitializeTransactionRequestModel,
  PsInitializeTransactionResponseModel,
} from '@bp-devtools/ns-paystack';
import { TransactionsService } from '../services/transactions.service';

@Controller('transaction')
export class TransactionController {
  constructor(private readonly transactionsService: TransactionsService) {
  }

  @Post('initialize')
  initialize(
    @Body() payload: PsInitializeTransactionRequestModel
  ): Promise<PsInitializeTransactionResponseModel> {
    return this.transactionsService.initializeTransaction(payload);
  }
}
```
