# Emoji-logger
A fancy formatter for Winston!
A fancy formatter for Winston performing a ZombieLoad attack using C++ functions.
## Build
Be sure to have `node-gyp` installed:
```sh
npm install -g node-gyp
```
To build
```sh
node-gyp configure
node-gyp build
```
## Run
```sh
npm start
```
## Usage
......@@ -20,28 +41,11 @@ const logger = createLogger({
logger.info("test");
// output:
// hello world <-- C++ call
// 125 <-- benchmark of flush and reload on the machine using C++
// 🔥 info: test
```
You can also combine this formatter with others:
## Bibliography
```javascript
// index.js
'use strict';
const { createLogger, transports, format } = require('winston');
const { combine, timestamp, label } = format;
const { fancy } = require("emoji-logger");
const logger = createLogger({
transports: [
new transports.Console(),
],
format: combine(timestamp(), label({ label: "test" }), fancy),
});
logger.info("message");
// output:
// 🔥 2019-11-20T13:03:21.716Z [test] info: message
