pjp

PJP: Javascript Pre-processor | Module to make things easier for PHP developpers

Basic Setup

express = require("express");
bodyParser = require("body-parser");
cookieParser = require("cookie-parser");
expressFileUpload = require("express-fileupload");
expressSession = require("express-session");
app = express();

const pjp = require("pjp");

pjp(global);

app.use(bodyParser.urlencoded({
        "extended": true
}));
app.use(cookieParser());
app.use(expressFileUpload({
        "uriDecodeFileNames": true,
        "safeFileNames": true,
        "preserveExtension": 12,
        "useTempFiles": true,
        "tempFileDir": path.join(__dirname, "temp"),
        "parseNested": true,
        "uploadTimeout": 0
}));
app.use(expressSession({
        "secret": String(Math.floor(Math.random() * 100000000000)).concat(String(Date().now)), //You can replace it by your own secret, ex: "MyS3cR37"
        "cookie": {},
        "name": "PJPSID"
}));
app.use(pjp.router(global, "127.0.0.1", "localhost"));

//Actual code

app.listen((!process.env.PORT ? 8080 : process.env.PORT), function(err){
  if(err)
    throw err;
  console.log("Everything seems to work, welcomne to PJP !");
});

More set-up

* -> Mandatory

pjp(globalElement, bodyParserVerificationSkip, cookieParserVerificationSkip, expressFileUploadVerificationSkip, expressSessionVerificationSkip);K

*globalElement -> global
(moduleName)VerificationSkip -> Default to false, if set to true it will skip verifying if module exists (Only skip if you named the middleware another way)

app.use(pjp.router(globalElement, ip, domainName));

*globalElement -> global
*ip -> Your IP Address (127.0.0.1 or local or public, depends what are you doing)
domainName -> Your domain name if you have one, else don't put anything or put "localhost"

Example

express = require("express");
bodyParser = require("body-parser");
cookieParser = require("cookie-parser");
expressFileUpload = require("express-fileupload");
expressSession = require("express-session");
app = express();

const path = require("path");
const pjp = require("pjp");
const fs = require("fs");

pjp(global);

app.use(bodyParser.urlencoded({
	"extended": true
}));
app.use(cookieParser());
app.use(expressFileUpload({
	"uriDecodeFileNames": true,
	"safeFileNames": true,
	"preserveExtension": 12,
	"useTempFiles": true,
	"tempFileDir": path.join(__dirname, "temp"),
	"parseNested": true,
	"uploadTimeout": 0
}));
app.use(expressSession({
	"secret": String(Math.floor(Math.random() * 100000000000)).concat(String(Date().now)), //You can replace it by your own secret, ex: "MyS3cR37"
	"cookie": {},
	"name": "pjpSID"
}));
app.use(pjp.router(global, "127.0.0.1"));

app.get("/getMySourceCode", function(req, res){
	const $ = req.serverFunctions;
	if(!isset($._SERVER["PHP_AUTH_USER"]) || !isset($._SERVER["PHP_AUTH_PW"]))
	{
		header("WWW-Authenticate: Basic realm=\"PJP Example Realm\"", res);
		return res.status(401).send("You canceled authentication, no source code for you ! >:(").end();
		//Using return end the callback, so use it instead of exit;
	}
	else
	{
		if($._SERVER["PHP_AUTH_USER"] === "admin" && $._SERVER["PHP_AUTH_PW"] === "12345")
		{
			fs.readFile(__filename, "utf-8", function(err, data){
				if(err)
					console.log(err);
				//Verifying if there is an error reading the file
				res.send(htmlspecialchars(data));
			});
			//Replace __filename by "index.html" (for example) to read a file
			return;
		}
		else
		{
			return res.send("<div align=\"center\"><h1 style=\"font-size:72px;\"><font color=\"red\">FORBIDDEN !</font></h1></div>");
		}
	}
});

app.get("/*", function(req, res){ // app.get("/*") means http://website/everything (except /getMySourceCode) with HTTP GET
	const $ = req.serverFunctions;
	if(isset($._GET["name"]))
	{
		res.echo("Your name is "+htmlspecialchars($._GET["name"]).concat(" !"));
		//To concat use plus or .concat instead of Perl's dot.
	}
	else
	{
		res.echo(`
<form action="${req.path}">
	<input type="text" name="name"/>
	<button type="submit">Display my name !</button>
</form>
		`);
	//When you use `these strings` you can `put ${variables} and ${things() - 43}`
	}
});

app.listen((typeof process.env.PORT === "undefined" ? 8080 : process.env.PORT), function(err){
	if(err)
	{
		throw err;
	}
	else
	{
		console.log("Everything seems to work, welcome to pjp !");
    //I'm bad at writing documentations.
	}
});

Features and things to know

At the beginning of a request's callback, put let $ = req.serverFunctions;. PHP -> PJP $_SERVER -> $._SERVER $_GET -> $._GET $_POST -> $._POST //Need body-parser $_FILES -> $._FILES //Need express-fileupload $_COOKIE -> $._COOKIE //To see cookies //Need cookie-parser $_COOKIE -> applyCookies(req, res) or res.cookie(name, value) //To write cookies //Need cookie-parser $_REQUEST -> $._REQUEST $_SESSION -> $._SESSION //Need express-session $_ENV -> $._ENV $_COOKIE -> $._COOKIE //To see cookies //Need cookie-parser $_COOKIE -> applyCookies(req, res) or res.cookie(name, value) //To write cookies //Need cookie-parser $http_response_header -> $.http_response_header $argc -> $.argc $argv -> $.argv $php_errormsg -> $.php_errormsg

isset(value) -> isset(value) htmlspecialchars(unsafeString) -> htmlspecialchars(unsafeString) explode(separator, originalString, limit) -> explode(separator, originalString, limit) header("HTTPHeader: Value") -> header("HTTPHeader: Value", res) header("HTTP/X.X CODE MEANING") -> res.status(CODE) urldecode(urlencoded) -> urldecode(urlencoded) or decodeURI(urlencoded) move_uploaded_file(from, to) -> move_uploaded_file(file, newPath, callback) Ex:

move_uploaded_file($\_FILE["image"], "./gallery/".concat($\_FILE["image"].name), function(err){
  if(err)
    throw err;
  res.status(200).end();
  return;
});```
include(script) -> include(script) //NOT IMPLEMENTED, WIP
echo text -> res.echo(text) or res.send(text)

Good luck ?
