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
Installation
$ yarn add @marblejs/middleware-logger
Requires @marblejs/core to be installed.
Importing
import { logger$ } from '@marblejs/middleware-logger';
Type declaration
logger$ :: LoggerOptions -> HttpMiddlewareEffect
Parameters
parameter
definition
options
<optional> LoggerOptions
LoggerOptions
parameter

silent
<optional> boolean
filter
<optional> HttpRequest -> boolean
Usage
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.response.statusCode >= 400;
  }),
  ...
];
​
export const listener = httpListener({
  middlewares,
  effects: [],
});
silent - When true the 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.
