# install deps
$ pnpm install
# init msw for browser mocking
$ pnpm msw:init
# Runs the app
$ pnpm start
# run test
$ pnpm test
# coverage with istanbul
$ pnpm test:coverage
Builds the app for production to the dist
folder.
It correctly bundles Svelte in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
# build app
$ pnpm build
You can deploy the dist
folder to any static host provider (netlify, surge, now, etc.)
Why use this over SvelteKit?
- It brings its own routing solution which might not be preferable for some users.
- It is first and foremost a framework that just happens to use Vite under the hood, not a Vite app.
This template contains as little as possible to get started with Vite + TypeScript + Svelte, while taking into account the developer experience with regards to HMR and intellisense. It demonstrates capabilities on par with the other create-vite
templates and is a good starting point for beginners dipping their toes into a Vite + Svelte project.
Should you later need the extended capabilities and extensibility provided by SvelteKit, the template has been structured similarly to SvelteKit so that it is easy to migrate.
Why global.d.ts
instead of compilerOptions.types
inside jsconfig.json
or tsconfig.json
?
Setting compilerOptions.types
shuts out all other types not explicitly listed in the configuration. Using triple-slash references keeps the default TypeScript setting of accepting type information from the entire workspace, while also adding svelte
and vite/client
type information.
Why include .vscode/extensions.json
?
Other templates indirectly recommend extensions via the README, but this file allows VS Code to prompt the user to install the recommended extension upon opening the project.
Why enable allowJs
in the TS template?
While allowJs: false
would indeed prevent the use of .js
files in the project, it does not prevent the use of JavaScript syntax in .svelte
files. In addition, it would force checkJs: false
, bringing the worst of both worlds: not being able to guarantee the entire codebase is TypeScript, and also having worse typechecking for the existing JavaScript. In addition, there are valid use cases in which a mixed codebase may be relevant.
Why is HMR not preserving my local component state?
HMR state preservation comes with a number of gotchas! It has been disabled by default in both svelte-hmr
and @sveltejs/vite-plugin-svelte
due to its often surprising behavior. You can read the details here.
If you have state that's important to retain within a component, consider creating an external store which would not be replaced by HMR.
// store.ts
// An extremely simple external store
import { writable } from 'svelte/store';
export default writable(0);
- fix all tests ->
typesafe-i18n
always returns empty string,,,axios
+svelte-query
+msw
base url somehow does not works. - add
/docs
folder, including all my decisions or technical considerations.
