SVR.JS Core is a library for static file serving, built from SVR.JS source code.
Example code (with Node.JS "http" module):
```javascript
var http = require("http");
var fs = require("fs");
var url = require("url");
var svrjsCore = require("svrjs-core").init(); // Initialize SVR.JS Core
var server = http.createServer(function (req,res) {
if(url.parse(req.url).pathname == "/useragent") {
res.writeHead(200, "OK", {"content-type": "text-plain"}); // Output as plain text
res.end("Your user agent: " + req.headers["user-agent"]); // Send user agent
} else {
svrjsCore(req,res); // Serve static content
}
}).listen(8888);
```
Example code (with Express):
```javascript
var express = require("express");
var svrjsCore = require("svrjs-core");
var app = express();
app.use(svrjsCore());
app.listen(3000);
```
## Methods
### *svrjsCore([config])*
Parameters:
- *config* - the SVR.JS Core configuration (optional, *Object*)
Returns: the request handler for use in Node.JS HTTP server or Express, with three parameters (*req*, *res*, and optional *next*)
The *config* object is almost the same format as SVR.JS configuration. You can read about SVR.JS configuration properties in [the SVR.JS documentation](https://svrjs.org/docs/config/configuration).
However, only these SVR.JS configuration properties apply to SVR.JS Core:
