Cordova supported platforms lack suport for ES6 Promise

[hsmith825]

I have not used promises before. I am getting snytactic errors in my cordova app. Research indicates that Cordova supported platforms lack suport for ES6 Promise. There is a plugin, PromisesPlugin, that says they rectifies this problem. Do you recommend this plugin for Cordova apps are should I do something else??

The particular syntax problem is of the form .then((message) => { . Your example will not build.

Thanks!

The es6-promise-plugin is installed. For others that run into this problem, I get it to work with statements of the form:
ApplePay.canMakePayments()
.then(function(message) {
// Apple Pay is enabled and a supported card is setup. Expect:
// 'This device can make payments and has a supported card'
console.log(message);
})
.catch(function(message) {
// There is an issue, examine the message to see the details, will be:
// 'This device cannot make payments.''
// 'This device can make payments but has no supported cards'
console.log("message);
});

Hi Howard,

Yes you're quite right. It's not the Promise in the older webviews that might be the problem, but it is the arrow functions that is shown in my examples.

The two snippets below are functionally identical.

Works in modern devices, or JavaScript projects using a transpiler:

.then((payment) => { });

Used in older devices, or non-transpiled projects:

.then(function(payment) { });
