Source code for Svelte Tutorials at MDN Web docs

Source code of the To-Do list app for the Svelte tutorials at [Understanding client-side JavaScript frameworks](Understanding client-side JavaScript frameworks) series at MDN Web docs.

08. Deployment and next Steps

In this article we will learn about a couple of zero-fuss options to deploy our app in production and see how to setup a basic pipeline to deploy our app to GitLab on every commit. We will also provide a list of Svelte resources to go further with your Svelte learning.

You can see the complete content of this article here or at MDN web docs.

The source code to follow this article is in the 08-next-steps folder, you can download it with the npx degit opensas/mdn-svelte-tutorial/08-next-steps svelte-todo command.

svelte app

This is a project template for Svelte apps. It lives at https://github.com/sveltejs/template.

To create a new project based on this template using degit:

npx degit sveltejs/template svelte-app
cd svelte-app

Note that you will need to have Node.js installed.

Get started

Install the dependencies...

cd svelte-app
npm install

...then start Rollup:

npm run dev

Navigate to localhost:5000. You should see your app running. Edit a component file in src, save it, and reload the page to see your changes.

By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the sirv commands in package.json to include the option --host 0.0.0.0.

Building and running in production mode

To create an optimised version of the app:

npm run build

You can run the newly built app with npm run start. This uses sirv, which is included in your package.json's dependencies so that the app will work when you deploy to platforms like Heroku.

Single-page app mode

By default, sirv will only respond to requests that match files in public. This is to maximise compatibility with static fileservers, allowing you to deploy your app anywhere.

If you're building a single-page app (SPA) with multiple routes, sirv needs to be able to respond to requests for any path. You can make it so by editing the "start" command in package.json:

"start": "sirv public --single"

Deploying to the web

With now

Install now if you haven't already:

npm install -g now

Then, from within your project folder:

cd public
now deploy --name my-project

As an alternative, use the Now desktop client and simply drag the unzipped project folder to the taskbar icon.

With surge

Install surge if you haven't already:

npm install -g surge

Then, from within your project folder:

npm run build
surge public my-project.surge.sh
