| What's new in Svelte: December 2020 | Better tooling, export maps and improvements to slots and context | Dani Sandoval | https://dreamindani.com |
It's the last "What's new in Svelte" of the year and there's lots to celebrate! This month's coverage includes updates from rollup-plugin-svelte, Sapper and SvelteKit and a bunch of showcases from the Svelte community!
New features & impactful bug fixes
$$props,$$restProps, and$$slotsare all now supported in custom web components (3.29.5, Example) andslotcomponents now support spread props:<slot {...foo} />(3.30.0)- A new
hasContextlifecycle function makes it easy to check whether akeyhas been set in the context of a parent component (3.30.0 & 3.30.1, Docs) - There is now a new
SvelteComponentTypedclass which makes it easier to add strongly typed components that extend base Svelte components. Component library and framework authors rejoice! An example:export class YourComponent extends SvelteComponentTyped<{aProp: boolean}, {click: MouseEvent}, {default: {aSlot: string}}> {}(3.31.0, RFC) - Transitions within
{:else}blocks should now complete successfully (3.29.5, Example) - Svelte now includes an export map, which explicitly states which files can be imported from its npm package (3.29.5 with some fixes in 3.29.6, 3.29.7 and 3.30.0)
rollup-plugin-sveltehad a new 7.0.0 release. The biggest change is that thecssoption was removed. Users who were using that option should add another plugin likerollup-plugin-css-onlyas demonstrated in the template
What's going on in Sapper?
Lots of new TypeScript definition improvements to make editing Sapper apps even easier! CSS for dynamic imports also should now work in client.js files. (Unreleased)
What's the deal with SvelteKit?
We're glad you asked! If you didn't catch Rich's blog post from early last month, you can find it here!
For all the features and bugfixes see the CHANGELOGs for Svelte and Sapper.
