expandify
Installation
npm install expandifyUsage
First create a HTML file with things you want to be evaluated (index.html).
<!DOCTYPE html>
<html>
<body>
<h1>Hey {"BOB".toLowerCase()}</h1>
<p>1+1 is equal to {1+1}</p>
</body>
</html>Then create a express application with the tool (index.js).
npm i expressconst expandify = require("expandify");
const express = require("express");
const app = express();
app.get("/", (req, res) => {
res.send(expandify(__dirname + "/index.html"));
});
app.listen(8080);Once you run the application, head to localhost:8080 and you will see all
the expressions evaluated!
Variables
You can also evaluate variables from your express application.
<!DOCTYPE html>
<html>
<body>
<h1>Hey {name}</h1>
<p>{greeting}</p>
</body>
</html>Then, when you call expandify() pass in the variables like this:
res.send(
expandify(__dirname + "/index.html", { name: "Bob", greeting: "How's life!" })
);Advanced Usage
You can even evaluate complex lists by mapping and then joining variables:
<!DOCTYPE html>
<html>
<body>
<ul>
{todos.map(todo => `<li>${todo}</li>`).join("")}
</ul>
</body>
</html>expandify(__dirname + "/index.html", { todos: ["Do chores", "Do homework"] })The possibilities are endless!
