Our Pledge

In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, religion, or sexual identity and orientation.

Our Standards

Examples of behavior that contributes to creating a positive environment include:

• Using welcoming and inclusive language

• Being respectful of differing viewpoints and experiences

• Gracefully accepting constructive criticism

• Focusing on what is best for the community

• Showing empathy towards other community members

Examples of unacceptable behavior by participants include:

• The use of sexualized language or imagery and unwelcome sexual attention or

  advances

• Trolling, insulting/derogatory comments, and personal or political attacks

• Public or private harassment

• Publishing others' private information, such as a physical or electronic

  address, without explicit permission

• Other conduct which could reasonably be considered inappropriate in a

  professional setting

Our Responsibilities

Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.

Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.

Scope

This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.

Enforcement

Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at opensource@tinkoff.ru. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.

Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

Because the plugin doesn't know which the library part will use in another application, it disabled tree shaking. Therefore bundles become large.

SharedLibraryWebpackPlugin is a webpack plugin for sharing libraries between applications.

Motivation

When the host application loads many micro apps bundled with a webpack, many JavaScript is loaded on a client page. In a perfect world, each app can share its libraries with other apps and meet the requirements:

1. Each app stays self-hosted.

2. Fallbacks for non-loaded packages.

3. Codesharing in runtime.

4. Different library versions work individually.

SharedLibraryWebpackPlugin came to us from a perfect world!

Documentations

Demo

We add SharedLibraryWebpackPlugin in each app build for sharing all Angular packages and zone.js.

const {
  SharedLibraryWebpackPlugin,
} = require('@tinkoff/shared-library-webpack-plugin');

module.exports = {
  plugins: [
    new SharedLibraryWebpackPlugin({
      libs: [
        { name: '@angular/core', usedExports: [] },
        { name: '@angular/common', usedExports: [] },
        { name: '@angular/common/http', usedExports: [] },
        { name: '@angular/platform-browser', usedExports: ['DomSanitizer'] },
        { name: '@angular/platform-browser/animations', usedExports: [] },
        { name: '@angular/animations', usedExports: [] },
        { name: '@angular/animations/browser', usedExports: [] },
        'zone.js/dist/zone',
      ],
    }),
  ],
};

After that, the client page loads 174.6kB of JavaScript! It is 38% less!

Installation

The plugin can install by any package manager.

npm i @tinkoff/shared-library-webpack-plugin -D

or

yarn add @tinkoff/shared-library-webpack-plugin --dev

Configuration

Add plugin to webpack configuration file and set a list of libraries for sharing. There is an example with lodash:

import { SharedLibraryWebpackPlugin } from '@tinkoff/shared-library-webpack-plugin';

module.exports = {
  plugin: [
    new SharedLibraryWebpackPlugin({
      libs: 'lodash',
    }),
  ],
};

The plugin adds one more chunk with a hashed name to the bundle. It should be a shared lodash. When the application is loaded, the webpack runtime will check if lodash is loaded.

How the plugin works

2. The plugin teaches entries and runtime to work with shared chunks.

How the app is loaded

1. Entry points and runtime are loaded.

2. Entry point checks if a shared required to run chunks are loaded and notifies the runtime about it.

3. Runtime downloads all not downloaded libraries and marks them as downloaded.

4. Runtime runs an app.
