@sevinf/maybe/dist/esm/allProperties.js

Maybe/Optional type implementation in Typescript. Main motivation for creating this library was handling `null` values in deeply nested data, coming from GraphQL APIs, but the library itself is not limited to GraphQL.

import { none, maybe, some } from './maybe';
export function allProperties(object) {
    var result = {};
    var keys = Object.keys(object);
    for (var _i = 0, keys_1 = keys; _i < keys_1.length; _i++) {
        var key = keys_1[_i];
        var value = maybe(object[key]);
        if (value.isNone()) {
            return none;
        }
        result[key] = value.orThrow();
    }
    return some(result);
}
