library2.0.7jsnpmunverified

my-framework-almaz (npm package `my-framework-almaz`, current stable version 2.0.7) is an educational frontend framework explicitly designed as a companion to the book "Build a frontend framework from scratch." Its primary purpose is to teach web developers the underlying mechanics of modern frontend frameworks, rather than for production application development. The framework evolves through different versions, mirroring chapters of the book, introducing core concepts like the Virtual DOM, implemented via `h()`, `hString()`, and `hFragment()` functions, and DOM manipulation functions such as `mountDOM()` and `destroyDOM()`. Early versions (like v1.0) utilized a simple state management pattern with a `Dispatcher` where any state change triggered a complete re-rendering of the entire view. Subsequent versions, starting from v2.0 (as indicated by the introduction of a 'reconciliation algorithm'), move towards more efficient partial DOM updates. Due to its pedagogical nature, it lacks the optimizations, security considerations, and robust feature set expected in production-grade frameworks. Its release cadence is likely tied to book updates and chapters.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

createApp

✓ import { createApp } from 'my-framework-almaz'

✗ const createApp = require('my-framework-almaz').createApp

Primarily designed for modern ES Modules environments.

✓ import { h } from 'my-framework-almaz'

✗ import h from 'my-framework-almaz'

The `h` function for creating Virtual DOM nodes is a named export, not a default.

mountDOM

✓ import { mountDOM } from 'my-framework-almaz'

✗ const { mountDOM } = require('my-framework-almaz')

Used to render the Virtual DOM into the actual browser DOM.

Dispatcher

✓ import { Dispatcher } from 'my-framework-almaz'

The Dispatcher class is used for simple command-based state management, especially in earlier versions.

This example demonstrates how to create a simple interactive application using `createApp`, `h` for Virtual DOM creation, `mountDOM` for rendering, and the `Dispatcher` for state management. It illustrates an initial render and subsequent full re-renders (characteristic of v1.0) when state changes via dispatched commands.

import { createApp, h, mountDOM, Dispatcher } from 'my-framework-almaz'; interface State { message: string; count: number; } const initialState: State = { message: 'Hello, my-framework-almaz!', count: 0, }; let appState = { ...initialState }; const dispatcher = new Dispatcher(); const UPDATE_MESSAGE = 'UPDATE_MESSAGE'; const INCREMENT_COUNT = 'INCREMENT_COUNT'; dispatcher.subscribe(UPDATE_MESSAGE, (payload: string) => { appState.message = payload; }); dispatcher.subscribe(INCREMENT_COUNT, () => { appState.count++; }); function renderApp() { return h('div', { id: 'my-app' }, [ h('h1', {}, appState.message), h('p', {}, `Count: ${appState.count}`), h('button', { onclick: () => { dispatcher.dispatch(INCREMENT_COUNT); updateView(); }, }, 'Increment Count'), h('button', { onclick: () => { dispatcher.dispatch(UPDATE_MESSAGE, 'Updated message from command!'); updateView(); }, }, 'Update Message'), ]); } const app = createApp(renderApp); function updateView() { const rootElement = document.getElementById('app-root'); if (rootElement) { while (rootElement.firstChild) { rootElement.removeChild(rootElement.firstChild); } mountDOM(app.render(), rootElement); } } document.addEventListener('DOMContentLoaded', () => { const root = document.createElement('div'); root.id = 'app-root'; document.body.appendChild(root); updateView(); });

Known issues

gotchaThis framework is explicitly NOT intended for production use. It is a pedagogical tool for learning frontend framework internals and should not be deployed in live applications due to potential performance, security, and stability limitations.

fix

Always use a battle-tested, production-ready framework (e.g., React, Vue, Angular) for real-world applications. Consult `my-framework-almaz` only for educational purposes.

affects: >=1.0

breakingVersion 1.0 of the framework (corresponding to Chapter 6 of the book) implements state changes by fully destroying and recreating the DOM on every update. Later versions introduce a 'reconciliation algorithm' to efficiently update only changed parts of the DOM, which implies significant internal architectural changes and potentially different patterns for component lifecycle and updates.

fix

When migrating between major versions, especially from v1.0, review the updated chapter and examples in the book for changes to the rendering pipeline, component structure, and state update mechanisms. Direct upgrades without code changes are unlikely to work.

affects: >=1.0 <2.0

gotchaAs an educational framework, `my-framework-almaz` may not prioritize security or performance optimizations typically found in production-grade libraries. Its code might be simplified to illustrate concepts rather than achieve maximum efficiency or robustness.

fix

Do not assume any inherent security features or performance guarantees. When adapting concepts for production, always consult best practices for your chosen production framework and perform thorough security audits and performance testing.

affects: >=1.0

Errors

Common errors & fixes

TypeError: Cannot read properties of undefined (reading 'mountDOM')

The `mountDOM` function was either not imported or the package was incorrectly installed/referenced, leading to `mountDOM` being `undefined`.

fix

Ensure `import { mountDOM } from 'my-framework-almaz';` is present at the top of your file and the `my-framework-almaz` package is correctly installed in your `node_modules`.

ReferenceError: h is not defined

The `h` function, used for creating virtual DOM nodes, was used without being imported.

fix

Add `import { h } from 'my-framework-almaz';` to the top of your JavaScript/TypeScript file where `h` is utilized.

DOM element not found (when mounting app)

The target DOM element specified for `mountDOM` (e.g., `document.getElementById('app-root')`) does not exist in the HTML document at the time `mountDOM` is called.

fix

Ensure your HTML includes the target element (e.g., `<div id="app-root"></div>`) and that `mountDOM` is called only after the DOM is fully loaded, typically within a `DOMContentLoaded` listener.
