Properly closing live query

[appy-one]

There currently is no way to stop a realtime query from delivering results, besides if returning false in one of the event callbacks. Waiting for a callback to happen might take a long time, so we need way to stop a realtime query upon request.

Suggestion:

const query = db.query('book').filter('rating', '==', ).on('add', bookAdded);
const snaps = await query.get();
// Some time later, stop the realtime query
await query.stop();

This has been added in acebase v1.21.0+ and acebase-client v1.16.0+ (or older version using latest acebase-core)

Hi, I was trying out this today,

this is my setup: acebase-server@1.11.0 acebase@1.21.7

I was connecting to AceBase server using a web app built on ReactJS with the browser client: https://cdn.jsdelivr.net/npm/acebase-client@1.17.0/dist/browser.min.js

and I was able to run live query and get updates as described in the documentation.

This is my query: this.db_listener = db.query('items') .filter('locationid', '==', mylocationid) .on('add', (match) => { console.log("Item ADD"); }).on('remove', (match) => { console.log("Item REMOVE"); }).on('change', (match) => { console.log("Item CHANGE"); });

When I'm trying to stop the live query with this: await this.db_listener.stop();

I see this kind of error in console: Uncaught (in promise) ReferenceError: socket is not defined stop browser.min.js:16 stop browser.min.js:16 componentWillUnmount MyComponent.jsx:119

Thanks for reporting, I'll look into it asap

I'm moving this issue to the acebase client repo

Looks like I was too quick to draw - this originally was an acebase issue. @TELECI-PROJECT you were have an issue using acebase-client v1.17.0 browser dist. Have you updated to the latest version to check if the issue has been resolved in the meantime?

[TELECI-PROJECT]

Hi, thanks, I don't see any errors in console after updating to the latest version (Acebase Client v1.20 and Acebase v1.27).

Great!
