What are the steps for implementing dependencies in a Vue component?

Although I typically work on backend development, I am now faced with the task of implementing something in an existing Vue codebase. In a file named myModal.vue, I need to incorporate a JavaScript library called cron-parser. When I utilize it in the app.js file, everything runs smoothly:

import CronParser from 'cron-parser';

let interval = CronParser.parseExpression('*/2 * * * *');
console.log(interval.next().toString()); // outputs a correct datetime

Now, my intention is to pass this CronParser to the myModal.vue file. Following the example of injecting HighCharts, I added a third line out of these four:

Vue.prototype.$eventHub = new Vue();
Vue.use(HighchartsVue);
Vue.use(CronParser);

let myModal = require('./components/myModal.vue');
// and additional components

Subsequently, within myModal.vue, I implement the same code:

let interval = CronParser.parseExpression('*/2 * * * *');
console.log(interval.next().toString());

However, I encounter the error:

"ReferenceError: CronParser is not defined"

I am feeling somewhat disoriented about where I might be making a mistake in this process. Could someone provide me with a clue in the right direction?

Answer №1

CronParser is not designed to be used as a Vue library, so there is no need to call Vue.use(CronParser);

Instead, ensure that you have imported it correctly in your myModal.vue. It appears that you may be missing the line

import CronParser from 'cron-parser';
within that file.
