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
