detect-templating-language^1.1.1

Detects various templating languages present in string

Install via npm

npm i detect-templating-language

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

Consume via a require():

const detectLang = require("detect-templating-language");

or as an ES Module:

import detectLang from "detect-templating-language";

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">

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

const detectLang = detectTemplatingLanguage;

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

Trivia

This program has 16 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, 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" }
);
