My app is running sluggish due to the excessive API calls for information retrieval. To optimize performance, I want to create a unified object containing all the data that can be shared across pages and accessed from localStorage, thus enhancing the app's fluidity. I am currently working on Angular 7 with Ionic 4. Thank you in advance.
Keeping all data in localStorage may not be the best approach, as localStorage only stores stringified objects (resulting in loss of methods). This would require additional steps to re-instantiate the Objects with the data from localStorage.
What is your reason for utilizing localStorage? Are you looking to persist data during page reloads? If not, consider using shared services. However, if data persistence is necessary and there is a specific point at which the saved data should be updated, then utilizing service workers to cache the data could be beneficial.
An alternative option is to utilize the localStorage, which solely accepts string values, necessitating you to serialize your data prior to storage. Perhaps it might be worth exploring converting your application into a PWA (Progressive Web App)? This could enable extensive caching capabilities to enhance the performance of your app, such as faster load times achieved by pre-caching files within the browser.
If you remain insistent on employing localStorage, the following approach can be taken:
var data = [{"test": {}}]; // Sample json data
localStorage.setItem(<KEY NAME>, JSON.stringify(data));
// To retrieve the stored data
var saved = localStorage.getItem(<KEY NAME>)
console.log(JSON.parse(saved));
