import hmpl from "hmpl-js";
const templateFn = hmpl.compile(
`<div>
<button data-action="increment" id="btn">Click!</button>
<div>Clicks: {{ "src": "/api/clicks", "after": "click:#btn" }}</div>
</div>`
);
const clicker = templateFn(({ request: { event } }) => ({
body: event.target.getAttribute("data-action"),
})).response;
document.querySelector("#app").append(clicker);Using HMPL, you can multiply reduce the size of the application bundle. Full customization of the request based on the modern fetch standard, as well as support for all the functionality necessary for modern work in applications (request indicator, sending by event, automatic generation of body for the form, caching) and the syntax of the object in the markup, which requires a minimum number of characters, will help to build interaction with the server and client as efficiently as possible.
- Customizable: Send a custom request to the server when receiving the UI
- Memory Preserving: Reduce file sizes on the client by several times
- Based on Fetch API: Use a modern standard instead of
XMLHTTPRequest - Server-oriented: Work with the server directly through markup and with a little js
- Generate thousands of DOM nodes from a single template: Work with large components not only on the server but also on the client
- Simple: Get ready-made UI from the server by writing a couple of lines of familiar object syntax
- Flexible: Can be used in almost any project due to not only working through a script, but also working in files with the
.hmplextension - No dependencies: Can connect from one js file
- Small bundle size: Lots of functionality in a couple of kilobytes
hmpl can be installed in several ways, which are described in this article. This tool is a simple javascript file that is connected in the usual way through a script, or using the import construct in an environment that supports this (webpack build, parcel build etc.). The first and easiest way is to install using a CDN.
This method involves downloading through npm or other package managers.
npm i hmpl-jsNode.js is required for npm.
Along the path node-modules/hmpl/dist you can find two files that contain a regular js file and a minified one.
You can install the package by simply downloading it as a file and moving it to the project folder.
<script src="./hmpl.min.js"></script>If, for some reason, you do not need the minified file, then you can download the full file from this link.
<script src="./hmpl.js"></script>The non-minified file is larger in size, but it is there as it is with all the formatting.
This method involves connecting the file through a third-party resource, which provides the ability to obtain a javascript file from npm via a link.
<script src="https://unpkg.com/hmpl-js/dist/hmpl.min.js"></script>

The documentation contains main information on how the HMPL template language works. If you have any questions about how HMPL works, you can use the following resources:
- Github - In the discussion and issues sections you can ask any question you are interested in.
- 𝕏 (Twitter) - There is a lot of interesting stuff there, concerning the template language and not only :)
You can also ask your question on Stack Overflow and address it in the resources described above.
We have a Contributing Guide that describes the main steps for contributing to the project.
