QUESTION
Curious what others are doing with SvelteKit adapter-node builds to put them into production.
For example...
- Serving pre-compressed files
- Setting a cache TTL
- Maybe something like
helmet
Is it better to define an entryPoint for the adapter like a server.js that implements polka/express/connect like this...
...ANSWER
Answered 2021-Oct-21 at 02:42After examining what adapter-node generates in the build folder, I decided to set the entryPoint property for the adapter's options in svelte.config.js to ./src/server.mjs which gets added to the build. The handle() method in hooks.js/ts doesn't allow for any control over the static content.
In the code below, I set a redirect for non-https and use helmet to beef up security.
QUESTION
Paint Worklet isn't working when it's placed inside an anchor tag.
Example Site: https://codepen.io/lonekorean/pen/aYoJPv
Above Example, Use
...ANSWER
Answered 2021-Jun-23 at 09:39This is actually intentional, to mitigate with a privacy leak that could happen if one were to paint :visited links. Here is a specs issue discussing this.
Basically an evil website could tell which link has been visited by applying a paint() only for such links and check if the PaintWorklet has been called.
So the current solution Chrome's team came with was to simply disable the PaintWorklet for all anchors with an href attribute, that is until the root problem gets properly addressed (but this will take time).
For the time being, to workaround that issue, you'd have to wrap your anchor element inside an other element an apply the paint on that wrapper element.
(Note that the bug also affects inner elements, so if you wanted to apply that paint on an element inside the anchor, that would become more complicated...)
QUESTION
I try to fetch login datas in a Svelte/Sapper app as in the code below and I use polka and axios for the api request on the server.
I don't understand the behaviour in the axios call. The console.log(JSON.stringify(result.data)) logs the correct result as I expected. But the fetch request on the client throws this exception:
Error: Failed to fetch
Can anyone explain me what I do wrong?
...ANSWER
Answered 2021-May-27 at 08:51The problem is solved after add preventDefault in the form element.
QUESTION
I have written a few apps using svelte and sapper and thought I would give sveltekit a go. All in all it works, but I am now running into the issue of registering a worker on ther server.
Basically I am trying to add socket.io to my app because I want to be able to send and receive data from the server. With sapper this wasn't really an issue because you had the server.js file where you could connect socket.io to the polka/express server. But I cannot find any equivalent in sveltekit and vite.
I experimented a bit and I can create a new socket.io server in a route, but that will lead to a bunch of new problems, such as it being on a separate port and causing cors issues.
So I am wondering is this possible with sveltekit and how do you get access to the underlying server?
...ANSWER
Answered 2021-May-20 at 08:12You cannot connect to a polka/express server because depending on the adapter you choose there can be no polka/express server used - if you deploy to a serverless platform for example. Sockets for serverless are not so easy to implement and their implementation depend on the provider.
You are raising an important concern but right now I'm afraid this is not possible - someone corrects me if I'm wrong.
What you still can do is to write your front with SvelteKit, build it as a static/SPA/node application and then use your build from your own polka/express server. You lose the swift development experience offered by SvelteKit though, since your development will be parted in two: first the client, then the server.

First of all, I know this topic looks really similar to this other topic talking about extending Express Request object using Typescript

Has anyone managed to do this?

Answered 2021-Apr-20 at 17:00map function is not native to objects. It is used to iterate an array and it also returns an array, and you are using it on objects. This is the correct implementation.
