# All the videos of Halfstack London 2024!

**By:** [Chris Heilmann](https://www.wearedevelopers.com/@chris-heilmann)

**Published:** December 16, 2024

Last month was [Halfstack London](https://halfstackconf.com/london), a conference about the web, JavaScript and half a dozen other things. We were there to deliver a talk, but also to record all the sessions and we're happy to share them with you. It took a bit as we had to wait for the slide decks to be inter-cut with the videos as our rig was really just a phone on a tripod with an external mic. Over the next few days we will also be releasing more detailed posts about each of the sessions, but we thought it'd be great to have them all before the holidays start. So, here we are.

[Ramona Schwering](https://www.ramona.codes/) takes us on a journey into automated tests and how they relate to Web security:
