});
console.log('api_key', api_key); // apk_f9cfa3c29500449828aebc910ce1d328
YourClass implements BufferBase
#!/usr/bin/env node
import { BufferBase } from 'nest-shared';
import { Buffer } from 'buffer';
import type { EncodeDataType, DecodeStrType } from 'nest-shared/lib/shared/types/buffer.type';
console.log(BufferBase.name); // BufferBase

return Buffer.from(data).toString('base64');
}
decode(str: DecodeStrType): string {
return Buffer.from(str, 'utf-8').toString('utf-8');
}
}
const bufferBaseImpl = new BufferBaseImpl();
const content = 'Hello World!';
console.log(bufferBaseImpl.encode(content)); // SGVsbG8gV29ybGQh
console.log(bufferBaseImpl.decode(content)); // Hello World!
