@marblejs/middleware-logger
HTTP request logger middleware for Marble.js
Simple middleware for request logging inside your console. It displays the outgoing request events using the following format:
{HTTP_METHOD} {PATH} {HTTP_STATUS} {TIME}
POST /api/v1/user 200 1ms
$ yarn add @marblejs/middleware-logger
Requires
@marblejs/core to be installed.import { logger$ } from '@marblejs/middleware-logger';
logger$ :: LoggerOptions -> HttpMiddlewareEffect
parameter | definition |
options | <optional> LoggerOptions |
parameter | definition |
silent | <optional> boolean |
filter | <optional> HttpRequest -> boolean |
- 1.Default behavior. Log every response to process.stdout:
import { httpListener } from '@marblejs/core';
import { logger$ } from '@marblejs/middleware-logger';
const middlewares = [
logger$(),
...
];
export const listener = httpListener({
middlewares,
effects: [],
});
2. Customized logging behavior:
import { httpListener } from '@marblejs/core';
import { logger$ } from '@marblejs/middleware-logger';
import { isTestEnv } from './util';
const middlewares = [
logger$({
silent: isTestEnv(),
filter: req => req.res.status >= 400;
}),
...
];
export const listener = httpListener({
middlewares,
effects: [],
});
- silent - When
truethe logging is turned off (usually useful during testing), - filter - Filter outgoing responses or incoming requests based on given predicate. For example we can log only HTTP status codes above 400.
