Jitsi Meet - Deploy new version - cache busting

#1

Hi,

When using jitsi and deploying a new version on my server,
my user needs to do a hard refresh in order to get latest version of the library and app bundle.

We can see in the HTML pages that the files are required with a query param, fixed to 139 : https://github.com/jitsi/jitsi-meet/blob/master/index.html#L159

When I go on the official Jitsi instance https://meet.jit.si/, the query param is updated to latest version.

I was not able to find in the webpack configuration where that could append.
I was also thinking this might be done one the CI, but could not see where.

If anyone could guide me to have the same behavior, that would be really helpfull.

Thanks,

That is done in our ci, the code is not available in a script, but will be at some point, it is part of larger plan for changing version scheme …

# Use the jitsi-meet package version as the version for app.bundle.js
sed -i.bak  -e "s/app.bundle.min.js?v=[[:digit:]]*/app.bundle.min.js?v=$VERSIONMIN/" index.html
sed -i.bak  -e "s/lib-jitsi-meet.min.js?v=[[:digit:]]*/lib-jitsi-meet.min.js?v=$VERSIONMIN/" index.html
sed -i.bak  -e "s/all.css/all.css?v=$VERSIONMIN/" index.html
sed -i.bak  -e "s/interface_config.js?v=[[:digit:]]*/interface_config.js?v=$VERSIONMIN/" index.html
....
....
dpkg-buildpackage -A -rfakeroot -us -uc

This is it what you are interested ^, the versions on meet.jit.si differ a little from those in the opensource package, as there is branding applied for meet.jit.si like the welcome page for example and some other close page changes and that’s it.
