Since its break­through in 2019, Svelte has con­tin­ued to amaze many fron­tend devel­op­ers around the globe with its ease of use and acces­si­bil­i­ty. Part of this was a sur­pris­ing­ly sta­ble core API, with most­ly just addi­tive changes over the years. This all changes with the upcom­ing release of Svelte 5, which intro­duces a host of new and bet­ter abstrac­tions for reac­tiv­i­ty, event han­dling and reusabil­i­ty of markup, while remain­ing back­wards com­pat­i­ble. In this talk, I’ll intro­duce you to the new mechan­ics and teach you the basics of Svelte along the way. This ses­sion is suit­able for every devel­op­er inter­est­ed in the broad­er fron­tend ecosys­tem, as well as sea­soned Svelte devel­op­ers look­ing for guid­ance on the com­ing updates.
