@universis/access-log

An express middleware for creating apache-like access logs

Install

npm i @universis/access-log

Usage

Use accessLog middleware:

    import express from 'express';
    import {accessLog} from '@universis/access-log';

    # create application
    app = express()
    # register access log middleware
    app.use(accessLog({
        filename: 'access.log',
        format: 'combined',
        interval: '1d'
    }));

The available options are the same as the options of rotating-file-stream package with an additional format property that accepts a string or a function that returns a string. The format property is used to specify the format of the access log. The default value is combined. You can read more about the available formats in the morgan documentation.

or use AccessLogger service when an @themost/common#ApplicationBase instance is available:

    import express from 'express';
    import {AccessLogger} from '@universis/access-log';

    # create application
    app = express()

    # create an instance of ExpressDataApplication
    const dataApplication = new ExpressDataApplication();

    # register access log service
    dataApplication.useService(AccessLogger);

    // register access log middleware
    app.use(dataApplication.getService(AccessLogger).middleware());
