    Transliterate Service for Angular

    GitHub Actions Status Azure Pipeline Status codecov npm version Gitter

    General-purpose transliteration service for Angular applications which can be used in swapping letters such as α → a, ၎ → ၎င်း or Zawgyi-One to standard Myanmar Unicode.


    • Can transliterate/convert any script or Unicode letters by using from a simplest rule definition (just with from and to rules) to more powerful rule definition (with tplVar, tplSeq, when, postRules, etc.)
    • Can use transliteration rules in both design-time and run-time with JSON file which can be loaded lazily or eagerly using extendable TranslitRuleLoader (see built-in HttpTranslitRuleLoader for implementation demo)
    • Can transliterate input phase by phase
    • Can define template variables with tplVar to reduce JSON size and to avoid repetition
    • Can define template loop sequences with tplSeq for sequential rules checking and replacement
    • Quick test input string checking with quickTests and minLength options for better performance
    • Can check converted left portion string with hasLeft boolean option and left regular expression option
    • Can check right part after matched input string with right regular expression option
    • Conditional rules processing with when and skip options
    • Can define post-rules with postRules for step-by-step conversions
    • Can use postRulesDef and postRulesRef to reduce JSON size and to avoid repetition in defining postRules
    • Conversion trace information can be included in output result for debugging purpose
    • Work with latest versions of Angular
    • Compatible with Angular Universal (Server Side Rendering - SSR)
    • Powered with RxJS

    export class AppComponent {
      constructor(private readonly translitService: TranslitService) {
        const zg2uniRules: TranslitRuleItem[] = [{
          from: '\u103B([\u1000-\u1021])',
          to: '$1\u103C'
          from: '\u1039',
          to: '\u103A'
        this.translitService.translit('ျမန္မာစာ', 'zg2uni', zg2uniRules)
          .subscribe(result => {
            // output: မြန်မာစာ
            console.log('output: ', result.outputText);
