regex-is-jsp^1.1.1

Regular expression for detecting JSP (Java Server Pages) code

Install via npm

npm i regex-is-jsp

The default is exported, so instead of isJSP below, you can name the consumed function however you want.

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">

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

const isJSP = regexIsJsp;

This isJSP is your main function. See its API in the main section.

Trivia

This program has 28 assertions in its unit tests. That's less than all unit test assertions' median (50) and less than geometric mean (70).

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
);
