What are @types/pino-std-serializers's main functionalities?
HTTP Request Serializer
This feature allows you to serialize HTTP request objects for logging. The `asReqValue` function converts the request object into a format suitable for logging.
const pino = require('pino');
const { asReqValue } = require('pino-std-serializers');
const logger = pino({
serializers: {
req: asReqValue
}
});
const req = { method: 'GET', url: '/test', headers: { host: 'localhost' } };
logger.info({ req }, 'Request received');
HTTP Response Serializer
This feature allows you to serialize HTTP response objects for logging. The `asResValue` function converts the response object into a format suitable for logging.
const pino = require('pino');
const { asResValue } = require('pino-std-serializers');
const logger = pino({
serializers: {
res: asResValue
}
});
const res = { statusCode: 200, headers: { 'content-type': 'application/json' } };
logger.info({ res }, 'Response sent');
Error Serializer
This feature allows you to serialize error objects for logging. The `asErrValue` function converts the error object into a format suitable for logging.
const pino = require('pino');
const { asErrValue } = require('pino-std-serializers');
const logger = pino({
serializers: {
err: asErrValue
}
});
const error = new Error('Something went wrong');
logger.error({ err: error }, 'Error occurred');
