kandi X-RAY | svelte-preprocess Summary
Svelte's own parser understands only JavaScript, CSS and its HTML-like syntax. To make it possible to write components in other languages, such as TypeScript or SCSS, Svelte provides the preprocess API, which allows to easily transform the content of your markup and your style/script tags. Writing your own preprocessor for, i.e SCSS is easy enough, but it can be cumbersome to have to always configure multiple preprocessors for the languages you'll be using. svelte-preprocess is a custom svelte preprocessor that acts as a facilitator to use other languages with Svelte, providing multiple features, sensible defaults and a less noisy development experience. It is recommended to use with svelte.config.js file, located at the project root. For other usage, please refer to usage documentation.

QUESTION
I'm exploring SvelteKit for the first time, I built my simple first application and I'd like to deploy it to my Apache server as a static page
As far as I understood adapter-static is the way to go, so I installed it and changed my svelte.config.js file to this:
...ANSWER
Answered 2022-Mar-20 at 16:05Ok I found out that I was setting the wrong parameters, so I fixed it and here's the working config.svelte.js (meaning that this configs actually set your static files to the custom path, that must be absolute):
QUESTION
I have been trying to generate RSS feed for my website. Although it perfectly works in the dev environment, the xml file is not generated when building for production.
Since I have created some json files in the same way and those are properly generated, I suspect xml.ts format might not be regarded as the build target.
Does anyone know the solution?
source code (src/routes/rss.xml.ts) ...ANSWER
Answered 2022-Mar-16 at 07:55One likely cause is that you do not have anything linked to this endpoint.
When SvelteKit builds your static page it will start at home page (index.svelte) and crawl your entire site, "clicking" on each link, rendering the page and writing it to the filesystem. But this means that any non-linked pages will not be rendered.
It could be this is your issue, if so simply add a link somewhere to rss.xml and it will generate that page correctly as well.

...ANSWER
Answered 2022-Feb-24 at 21:54The issue in svelte-preprocess/src/transformers/typescript.ts line 497
if (filename == null) return { code: content };
When you call svelte.preprocess without the "optional" filename the typescript preprocessor does nothing.
Call preprocess with the third argument to fix the issue:

ANSWER
Answered 2022-Jan-05 at 07:01I fixed the issue by setting up Svelte Language-server: Runtime on VSCode
Go to File > Preferences > Settings search svelte in searchbox, then find Svelte > Language-server: Runtime
After that, add full path node.exe (e.g: C:\\Program Files\\nodejs\\node.exe) to Svelte > Language-server: Runtime

Error in svelte.config.js
Error [ERR_MODULE_NOT_FOUND]: Cannot find package '$app' imported from /Users/username/projects/my-app/svelte.config.js

...ANSWER
Answered 2021-Dec-14 at 14:56Great question. The solution is this, you cannot use the $app inside the config file if you would ever need the environment you need, you can use process.env.NODE_ENV which returns strings production and development
Change your svelte.config.js to this.

When importing the library modbus-serial into the App.svelte component of a new app (import ModbusRTU from "modbus-serial" or const ModbusRTU = require("modbus-serial")), I keep getting the following error on the console:
ANSWER
Answered 2021-Oct-31 at 16:56This problem may be caused by the mixing of commonjs require & esm import statements in the same project. Adding transformMixedEsModules to the config of @rollup/plugin-commonjs should help somewhat resolve the issue:
