Open Platform Web App Load Time

I made an app that does the same thing Fraser, I load web app items in chunks, can do over 1k in about 5-10 seconds. But I have already reported to BC how slow the bcapi.js methods are. They say to use them but I do not for that reason.

Hi Fraser,

We are currently investigating the sdk to see why it is slow in some cases. Meanwhile, I took a look at your app code. What happens at the moment is that you have a  grid with multiple pages and your app load all vacancies (762 items at the moment) before displaying the grid. This mean the browser does 763 API requests before displaying any useful information.

In my opinion, a better way to make your application responsive is to make a request for obtaining the items count and another 10 requests for fetching the first page of your application. This will significantly improve your application load time.

Can you please try to rewrite your app as suggested here and tell me if you see any improvements?

Kind regards,

Radu

Which is what I do, I load chunks.

As a question Radu - Right now on live servers - the "All" element for web app items in terms of modules and API - IS this load based now? I can do it and load 600+ items one site and then another site it is 548... etc.

For modules yes, for APIs no. For web app items API and other APIs, where is actually a PARSE query object which applies conditions on attributes belonging to the API resource (e.g web app item attributes). Below you can find a simple example for listing all web app items which name contains with "abc".

GET /api/v2/admin/sites/123/webapps/TestWebapp1/items?where={"name": {"$contains": "abc"}}.

I know you load chunks of data, but I was explaining to Fraser that for his specific use case there is no need to load more than 10 items. Afterwards, his app is perfectly usable for his users. Of course he can continue to load more data in background if he wants but it is not necessary.

I guess they will be using a filter plugin of some sort.

Many of those have means to dynamically add more items to them and that will be in the documentation. If not they can look at other ones.

But the API access is still slow. As I have posted in another post, Radu and team say to use the BCAPI.js methods but if they switch to the direct API endpoints they will find it a bit quicker.
