Getting Started

This package is available in the Node Package Repository and can be easily installed with npm or yarn.

# or
$ yarn add @slimio/logger

Usage example

});
for (let id = 0; id < 10; ++id) {
    log.writeLine("hello world!");

API

constructor(fd?: string | number, options?: Logger.ConstructorOptions)

Create a new Logger. The default value of fd is process.stdout.fd.

Options is described by the following TypeScript interface:

interface ConstructorOptions {
    title?: string;
    local?: string;
}

writeLine(msg?: string): void

Write a new line in the write stream. If the msg is undefined or equal to Empty String, then we write \n in the WriteStream.

log.writeLine("hello");
log.writeLine(void 0);
log.writeLine("bye bye !");

It will produce the following stdout

[my-log] Jul 10, 2019, 3:24:25 PM - hello

[my-log] Jul 10, 2019, 3:24:25 PM - bye bye !

close(): Promise< void >

Close and flush the stream.
