Example

Pre-fetching a set of strings to use later

import prefetch from 'core/prefetch';

// A single string prefetch.
prefetch.prefetchString('error', 'cannotfindteacher');

// Prefetch multiple strings in the same component.
prefetch.prefetchStrings('core', [
    'yes',
    'no',
]);

// Use the strings.
import {get_string as getString, get_strings as getStrings} from 'core/str';
getString('cannotfindteacher', 'error')
.then(str => {
    window.console.log(str); // Cannot find teacher
})
.catch();
getStrings([
    {
        key: 'cannotfindteacher',
        component: 'error',
    },
    {
        key: 'yes',
        component: 'core',
    },
    {
        key: 'no',
        component: 'core',
    },
])
.then((cannotFindTeacher, yes, no) => {
    window.console.log(cannotFindTeacher); // Cannot find teacher
    window.console.log(yes); // Yes
    window.console.log(no); // No
})
