regex-is-jsp^2.1.0

Regular expression for detecting JSP (Java Server Pages) code

Install via npm

npm i regex-is-jsp

Consume via a require():

const { isJSP } = require("regex-is-jsp");

or as an ES Module:

import { isJSP } from "regex-is-jsp";

Install as a script, via CDN

Put this in your HTML:

<script src="https://cdn.jsdelivr.net/npm/regex-is-jsp/dist/regex-is-jsp.umd.js"></script>

Then, you’ll get a global variable regexIsJsp in your Global object and you consume it like this:

const { isJSP } = regexIsJsp;

Trivia

This program has 25 assertions in its unit tests. That's less than all unit test assertions' median (49) and less than geometric mean (73).

In monorepo, one other package, detect-templating-language, consumes this package.

Quick Take

import { strict as assert } from "assert";
import { isJSP } from "regex-is-jsp";

// detects JSP code
assert.equal(
  isJSP().test(`<div><% out.println("Hi!"); %></div>`),
  true
);

// in case if it's not nunjucks
assert.equal(
  isJSP().test(`<div>tralala</div>`),
  false
);
