dk-localize v3.2.14

Library for injecting texts into templates

Currently suits English-only projects. Features are limited, development is in progress in accordance to my needs

Installation

Add dk-localize to package.json and install.

Usage

1. Allow usage of __dirname in you builder. For Webpack it is { node: { __dirname: true } }

2. Attach getLn to the place where localized text will be located, ex.:

import { getLn as getLnNotBound, TypeTranslations } from 'dk-localize';

class GlobalStore {
  ln: TypeTranslations = {};
};

const store = new GlobalStore();

const getLn = getLnNotBound.bind(null, store.ln);

3. Pass getLn to components (ex. in React by Context)

import { createContext } from 'react';
import { render } from 'react-dom';

const StoreContext = createContext(undefined);

render(
  <StoreContext.Provider value={{ getLn }}>
    <App />
  </StoreContext.Provider>,
  document.getElementById('app')
)

4. Create file with default texts, ex. src/page/messages.ts

import { wrapMessages } from 'dk-localize';

export const messages = wrapMessages(__dirname, {
  title: 'Hello {user}',
});

5. Use in components, ex. in React src/page/Page.tsx

import { Component, ContextType } from 'react';
import { messages } from './messages';
import { StoreContext } from '/StoreContext';

type TypeContext = ContextType<typeof StoreContext>;

export class PushMessagesList extends Component {
  static context: TypeContext;
  static contextType = StoreContext;
  declare context: TypeContext;
  
  render() {
      const { getLn } = this.context;
      
      return <>{getLn(messages.title, { user: 'John' })}</>
  }
}

Features

• wrapMessages creates uniq names for every key by __dirname, so in the example above it will be src/page__title

Coming features:

• preparation of JSON files that can be uploaded to localization system

Plugins

Dynamic variables

Dynamic value must follow in brackets, supported value types are string | number, ex.

// mesages.ts
import { wrapMessages } from 'dk-localize';

export const messages = wrapMessages(__dirname, {
  title: 'Name: {firstName}, age: {age}',
});

// component
getLn(messages.title, { firstName: 'John', age: 25 }) // 'Name: John, age: 25'

Plurals

Plural value must follow in brackets, supported value type is number, ex.

// mesages.ts
import { wrapMessages } from 'dk-localize';

export const messages = wrapMessages(__dirname, {
  title: '{count: One,Many} {count: apple,apples}',
});

// component
getLn(messages.title, { count: 1 }) // 'One apple'
getLn(messages.title, { count: 2 }) // 'Many apples'

Syntax is {param: textForOne,textForMany}. Extra spaces and special symbols for texts are currently not supported, only [a-zA-Z0-9].
