🚀 Simple express.js tool to evaluate expressions in HTML templates.

Installation

npm install expandify

Usage

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 express

const 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!
