detect-templating-language^3.0.1

Detects various templating languages present in string

Install via npm

npm i detect-templating-language

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required:

import { detectLang } from "detect-templating-language";

If you need a legacy version which works with require, use version 2.1.0:

"detect-templating-language": "2.1.0",

Install as a script, via CDN

Put this in your HTML:

<script src="https://cdn.jsdelivr.net/npm/detect-templating-language/dist/detect-templating-language.umd.js"></script>

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

const { detectLang } = detectTemplatingLanguage;

Trivia

This program has 13 assertions in its unit tests. That's less than all unit test assertions' median (48) and less than geometric mean (70).

In monorepo, one other package, stristri, consumes this package.

Quick Take

import { strict as assert } from "assert";
import { detectLang } from "detect-templating-language";

// detects Nunjucks
assert.deepEqual(
  detectLang(
    `<div>{% if something %}x{% else %}y{% endif %}</div>`
  ),
  { name: "Nunjucks" }
);

// detects JSP (Java Server Pages)
assert.deepEqual(
  detectLang(
    `<div><c:set var="someList" value="\${jspProp.someList}" /></div>`
  ),
  { name: "JSP" }
);
