Replace string in a text file in node.js

Question

I am using node.js. I want to read a file with some placeholder strings and replace them dynamically before I serve the file. This is not an HTML file, so a templating engine will not work.

How can I do this?

Answer 1

If a template engine is overkill just use string.replace().

temp = "Hello %NAME%, would you like some %DRINK%?";

temp = temp.replace("%NAME%","Michael Dillon");
temp = temp.replace("%DRINK%","tea");
console.log(temp);

With only a bit more work you could make a general purpose template function based on just the standard methods in the String object.
