Property 'share' does not exist on type 'Navigator'

Based on this answer, you can try to define a variable of type any and assign to it your value of Type Navigator. The isssue is related to typeScript typings.

let newVariable: any;newVariable = window.navigator;if (newVariable && newVariable.share) {  newVariable.share({    title: 'title',    text: 'description',    url: 'https://soch.in//',  })    .then(() => console.log('Successful share'))    .catch((error) => console.log('Error sharing', error));} else {  alert('share not supported');}

Another option would be to extend the interface Navigator as it is suggested in the link I posted above.

For anyone looking for a proper answer, just add this to your global.d.ts file:

type ShareData = {    title? : string;    text? : string;    url? : string;};interface Navigator{    share? : (data? : ShareData) => Promise<void>;}

This properly reflects the level 1 API.

This also works and we don't need to create a newVariable.

if (window.navigator && window.navigator.share) {  window.navigator['share']({    title: 'title',    text: 'description',    url: 'https://soch.in//',  })    .then(() => console.log('Successful share'))    .catch((error) => console.log('Error sharing', error));} else {  alert('share not supported');}
