Turn FHIR Dosage into human readable text in your wanted language and much more with fhir-dosage-utils

import FhirDosageUtils from "fhir-dosage-utils";



// See https://jy95.github.io/fhir-dosage-utils/api/interface/Params for more info about config

const config = {

  language: "en",

};



// A FHIR Dosage example

const dosage = {

  timing: {

    repeat: {

      frequency: 1,

      period: 8,

      periodUnit: "h",

    },

  },

};



// Prepare utility class

let dosageUtils = await FhirDosageUtils.build(config);



// 1. You can turn dosage(s) to text

// display "1 time every 8 hours"

console.log(dosageUtils.fromDosageToText(dosage));

console.log(dosageUtils.fromMultipleDosageToText([dosage]));



// 2. You can extract part(s) of dosage, to your liking

// display "every 8 hours"

console.log(

  dosageUtils.getFields(dosage, "periodPeriodMax" /*, other parameters*/),

);



// 3. You can detect if Dosage objects contains only "sequential" instructions

// display "true"

console.log(dosageUtils.containsOnlySequentialInstructions([dosage]));



// 4. Turn this array of Dosage objects into a data structure useful to handle "sequential" and "concurrent" instructions (cf. "sequence" property).

// Display "[ [dosage] ]"

console.log(dosageUtils.groupBySequence([dosage]));



// ... And many things
