fix(website): scale hero mocks to the viewport width - #422
The hero mocks are illustrations of a fixed-size window, but on narrow screens they either reflowed into a cramped stacked layout (chat, routing map) or crushed their content (Claude Code session). They now render at a fixed 940×640 and are scaled down to the available width, so they read like a screen recording on any device. The per-mock mobile media queries are removed.
The docs delegation diagram had the same problem, plus a fallback that hid the DevSpace box on phones. It now goes through a small reusable Fit wrapper that lays it out at 720px and scales it to its container.
The landing workflow section and the docs workflow run are intentionally left alone: they are real code and status lists that stack readably, and scaling would shrink the text to illegibility.
Checked in headless Chromium at 375px, 700px/768px and 1280px; screenshots are in the comment below.
Chat layouts retain their two-column design on narrow screens instead of switching to a stacked layout.
Routing maps keep their columns, diagram details, and labels visible on narrow screens.
Hero panels scale down to fit the viewport while preserving their fixed layout rather than reflowing into a mobile-specific design.
Delegation diagrams scale down to fit narrow viewports while retaining their fixed layout and diagram details. These layouts remain consistent across screen sizes, with content scaled to fit where needed.
HeroStage and DelegationDiagram scale fixed-width layouts to fit available width. ChatMock and RoutingMap retain their base layouts at narrow widths. The Wrangler configuration adds preview and observability settings.
HeroStage wraps its panels in a viewport and uses ResizeObserver to scale fixed 940×640 mock dimensions based on viewport width.
Fit the delegation diagram website/islands/Fit.tsx, website/islands/DelegationDiagram.tsx, website/ui/routing.css
The new Fit component scales fixed-width content to fit its outer width and adjusts the outer height. DelegationDiagram uses it with a 720px design width. The narrow-viewport rules for the diagram are removed.
Retain base layouts on narrow viewports website/landing/home/ChatMock.astro, website/landing/home/RoutingMap.astro
The max-width: 820px rules are removed. Narrow viewports use the base layouts.
Wrangler preview and observability configuration
Layer / File(s)
Summary
Add preview and observability settings website/wrangler.jsonc
The configuration adds an empty top-level previews block. It enables logs with invocation logs and persistence, and disables traces with persistence configured.
Waishnav/devspace#420: Adds website components and styles that this change updates, including the landing layouts and Wrangler configuration.
Merge Risk: Low · up to 504d1
The new logging configuration probably will not capture the site's static asset requests, so the intended observability may not materialize. Site behavior and the responsive layout fixes are unaffected. It is mergeable if the team accepts or follows up on this logging gap.

Provide a readable view of the mocks on narrow screens.
At a 375px viewport, the parent padding leaves about 313px for the mock. This scale reduces its 12px text to about 4px, so visitors cannot read the session details or routing labels. (raw.githubusercontent.com)
Keep the scaled overview, but provide an expandable or scrollable view at a readable size.

# Workers Logs
Last updated Oct 12, 2026|Copy as Markdown|View as Markdown|Agent setup
[Select]
Workers Logs lets you automatically collect, store, filter, and analyze logging data emitted from Cloudflare Workers. Data is written to your Cloudflare Account, and you can query it in the dashboard for each of your Workers. All newly created Workers will come with the observability setting enabled by default.
Logs include invocation logs, custom logs, errors, and uncaught exceptions.
To group related exceptions, failed invocations, and error logs, use Workers Issues.
Image: Example showing the Workers Logs Dashboard
To send logs to a third party, use OpenTelemetry export (recommended), Workers Logpush, or Tail Workers.
Enable source maps so captured JavaScript and TypeScript exception stacks point to the original files and lines. Framework builds must generate maps as well as upload them.
## Enable Workers Logs
In scenario 1, the `user_id` is embedded within a message. To find all logs relating to a particular user_id, you would have to run a text match. In scenarios 2 and 3, your logs can be filtered against the keys `user_id` and `user_email`.
## Features
### Invocation Logs
Each Workers invocation returns a single invocation log that contains details such as the Request, Response, and related metadata. These invocation logs can be identified by the field `$cloudflare.$metadata.type = "cf-worker-event"`. Each invocation log is enriched with information available to Cloudflare in the context of the invocation.
In the Workers Logs UI, logs are presented with a localized timestamp and a message. The message is dependent on the invocation handler. For example, Fetch requests will have a message describing the request method and the request URL, while cron events will be listed as cron. Below is a list of invocation handlers along with their invocation message.
Invocation logs can be disabled in wrangler by adding the `invocation_logs = false` configuration.

<title>Logpush · Cloudflare Logs docs</title>
<location>https://developers.cloudflare.com/logs/logpush/</location>
<excerpt>citeturn1search1 [wordlim: 200] Crawled: today; Cloudflare Logpush supports pushing logs to storage services, SIEMs, and log management providers via the Cloudflare dashboard or API. ... An HTTP Requests record is about 1.5–3 kB uncompressed, depending on the fields selected. Each request produces one record, including Worker subrequests. ... There is currently a max limit of 4 Logpush jobs per zone.
# Logpush
Last updated Oct 22, 2026|Copy as Markdown|View as Markdown|Agent setup
[Select]
Logpush delivers logs in batches as quickly as possible, with no minimum batch size, potentially delivering files more than once per minute. This capability enables Cloudflare to provide information almost in real time, in smaller file sizes.
The push frequency is automatic and cannot be adjusted—Cloudflare pushes logs in batches as soon as possible. However, users can configure the batch size using the API for improved control in case the log destination has specific requirements.
Important limitation
Logpush only pushes logs once as they become available and cannot backfill historical data. If your job is disabled or fails, logs generated during that period are permanently lost. This is why configuring health notifications is essential for early detection of issues.
Logpush does not offer storage or search functionality for logs; its primary aim is to send logs as quickly as they arrive.
Cloudflare Logpush supports pushing logs to storage services, SIEMs, and log management providers via the Cloudflare dashboard or API.
## Estimating log volume
Before setting up a Logpush job, you can estimate the total volume of data that will be pushed to your destination. The volume depends on your traffic, the dataset, and the fields you select.
Logpush usage is measured in uncompressed bytes delivered, so estimate with uncompressed record sizes. For rates and included usage, refer to Pricing.
### Quick sizing for HTTP Requests
An HTTP Requests record is about 1.5–3 kB uncompressed, depending on the fields selected. Each request produces one record, including Worker subrequests.
* 100k requests/day → ~150–300 MB/day
* 1M requests/day → ~1.5–3 GB/day, or ~45–90 GB/month
* 10M requests/day → ~15–30 GB/day
* 100M requests/day → ~150–300 GB/day
Files arrive at your destination gzip-compressed, so they use roughly a tenth of the storage that the uncompressed volume suggests.
Extra fields and custom fields increase record size. Other datasets (Firewall, Workers, Load Balancing) add volume separately. For average record sizes by dataset, refer to Log Explorer pricing.
For precise estimates, you can sample your logs via Logpull using a 1-hour sample.
## Limits
There is currently a max limit of 4 Logpush jobs per zone. Trying to create a job once the limit has been reached will result in an error message: `creating a new job is not allowed: exceeded max jobs allowed`.
## Availability
| Free | Pro | Business | Enterprise
--- | --- | --- | --- | ---
Availability | Yes | Yes | Yes | Yes
Dataset availability depends on the Cloudflare products on your account. Workers Trace Events Logpush requires the Workers Paid plan and retains separate request-based pricing.
For usage rates and included monthly usage, refer to Pricing.</excerpt>

<excerpt>citeturn0search1 [wordlim: 200] Crawled: today; When you deploy your project, Cloudflare deploys both your Worker code and your static assets in a single operation. ... * Subsequent Requests: If a request for the same asset reaches a data center that does not have it cached, Cloudflare's tiered caching system allows it to be retrieved from a nearby cache rather than going back to storage.
# Static Assets
Last updated Oct 12, 2026|Copy as Markdown|View as Markdown|Agent setup
You can upload static assets (HTML, CSS, images and other files) as part of your Worker, and Cloudflare will handle caching and serving them to web browsers.
### How it works
When you deploy your project, Cloudflare deploys both your Worker code and your static assets in a single operation. This deployment operates as a tightly integrated "unit" running across Cloudflare's network, combining static file hosting, custom logic, and global caching.
The assets directory specified in your Wrangler configuration file is central to this design. During deployment, Wrangler automatically uploads the files from this directory to Cloudflare's infrastructure. Once deployed, requests for these assets are routed efficiently to locations closest to your users.
`{
"$schema": "./node_modules/wrangler/config-schema.json",
"name": "my-spa",
"main": "src/index.js",
"upload_source_maps": true,
});
}
return env.ASSETS.fetch(request);
},
};`
`from workers import WorkerEntrypoint, Response
from urllib.parse import urlparse
class Default(WorkerEntrypoint):
async def fetch(self, request):
# Example of serving static assets
url = urlparse(request.url)
if url.path.startswith("/api/):
return Response.json({"name": "Cloudflare"})
return await self.env.ASSETS.fetch(request)`
### Routing behavior
By default, if a requested URL matches a file in the static assets directory, that file will be served — without invoking Worker code. If no matching asset is found and a Worker script is present, the request will be processed by the Worker. The Worker can return a response or choose to defer again to static assets by using the assets binding (e.g. `env.ASSETS.fetch(request)`). If no Worker script is present, a `404 Not Found` response is returned.
The default behavior for requests which don't match a static asset can be changed by setting the `not_found_handling` option under `assets` in your Wrangler configuration file:
* `not_found_handling = "single-page-application"`: Sets your application to return a `200 OK` response with `index.html` for requests which don't match a static asset. Use this if you have a Single Page Application. We recommend pairing this with selective routing using `run_worker_first` for advanced routing control.
* `not_found_handling = "404-page"`: Sets your application to return a `404 Not Found` response with the nearest `404.html` for requests which don't match a static asset.
`{
"assets": {
"directory": "./dist",
"not_found_handling": "single-page-application"
}
}`
`[assets]
directory = "./dist"
not_found_handling = "single-page-application"`
If you want the Worker code to execute before serving assets, you can use the `run_worker_first` option. This can be set to `true` to invoke the Worker script for all requests, or configured as an array of route patterns for selective Worker-script-first routing:

Requests to the Worker script (for example, in the case of SSR content) are billed according to Workers pricing.
# Billing and Limitations
Last updated Apr 23, 2026|Copy as Markdown|View as Markdown|Agent setup
[Select]
## Billing
Requests to a project with static assets can either return static assets or invoke the Worker script, depending on if the request matches a static asset or not.
* Requests to static assets are free and unlimited. Requests to the Worker script (for example, in the case of SSR content) are billed according to Workers pricing. Refer to pricing for an example.
* There is no additional cost for storing Assets.
* Important note for free tier users: When using `run_worker_first`, requests matching the specified patterns will always invoke your Worker script. If you exceed your free tier request limits, these requests will receive a 429 (Too Many Requests) response instead of falling back to static asset serving. Negative patterns (patterns beginning with `!/`) will continue to serve assets correctly, as requests are directed to assets, without invoking your Worker script.
## Limitations
See the Platform Limits
## Troubleshooting
* `assets.bucket is a required field` — if you see this error, you need to update Wrangler to at least `3.78.10` or later. `bucket` is not a required field.</excerpt>

# Worker script
Last updated Oct 12, 2026|Copy as Markdown|View as Markdown|Agent setup
[Select]
If you have both static assets and a Worker script configured, Cloudflare will first attempt to serve static assets if one matches the incoming request. You can read more about how we match assets in the HTML handling docs.
If an appropriate static asset if not found, Cloudflare will invoke your Worker script.
This allows you to easily combine together these two features to create powerful applications (e.g. a full-stack application, or a Single Page Application (SPA) or Static Site Generation (SSG) application with an API).
## Cloudflare Access context
Note
When a Worker has Static Assets, the internal assets router does not pass `ctx.access` to the user Worker. Access still protects the Worker and its assets, but `ctx.access` is unavailable to the user Worker. For more information, refer to `ctx.access` limitations.
## Run your Worker script first
You can configure the `assets.run_worker_first` setting to control when your Worker script runs relative to static asset serving. This gives you more control over exactly how and when those assets are served and can be used to implement "middleware" for requests.
Caution
If you are using Smart Placement in combination with `assets.run_worker_first`, you may find that placement decisions are not optimized correctly as, currently, the entire Worker script is placed as a single unit. This may not accurately reflect the desired "split" in behavior of edge-first vs. smart-placed compute for your application. This is a limitation that we are currently working to resolve.

Configuring a Worker with assets requires specifying a directory and, optionally, an assets binding, in your Worker's Wrangler file. The assets binding allows you to dynamically fetch assets from within your Worker script (e.g. `env.ASSETS.fetch()`), similarly to how you might with a make a `fetch()` call with a Service binding.
Only one collection of static assets can be configured in each Worker.
## `directory`
The folder of static assets to be served. For many frameworks, this is the `./public/`, `./dist/`, or `./build/` folder.
`{
"$schema": "./node_modules/wrangler/config-schema.json",
"name": "my-worker",
// Set this to today's date
"compatibility_date": "2026-10-26",
"assets": {
"directory": "./public/",
},
}`
`"$schema" = "./node_modules/wrangler/config-schema.json"
name = "my-worker"
# Set this to today's date
compatibility_date = "2026-10-26"
[assets]
directory = "./public/"`
### Ignoring assets
Sometime there are files in the asset directory that should not be uploaded.
In this case, create a `.assetsignore` file in the root of the assets directory. This file takes the same format as `.gitignore`.
Wrangler will not upload asset files that match lines in this file.
Example
You are migrating from a Pages project where the assets directory is `dist`. You do not want to upload the server-side Worker code nor Pages configuration files as public client-side assets. Add the following `.assetsignore` file:
`_worker.js
_redirects
_headers`
Now Wrangler will not upload these files as client-side assets when deploying the Worker.
## `run_worker_first`
Controls whether to invoke the Worker script regardless of a request which would have otherwise matched an asset. `run_worker_first = false` (default) will serve any static asset matching a request, while `run_worker_first = true` will unconditionally invoke your Worker script.

<excerpt>citeturn0search4 [wordlim: 200] Published: last month; Crawled: yesterday; Requests to a project with static assets can either return static assets or invoke the Worker script, depending on if the request matches a static asset or not. ... Requests to the Worker script (for example, in the case of SSR content) are billed according to Workers pricing.

Use an HTTP request log source for static asset traffic.
Matching assets bypass Worker code, so observability.logs.invocation_logs does not record the site’s asset requests. Configure Cloudflare’s HTTP Requests Logpush dataset, or add a Worker and route requests through it with run_worker_first if Worker-based logs are required.

Review comment at @website/wrangler.jsonc at line 19:
Update the observability configuration around invocation_logs to capture static
asset requests through Cloudflare’s HTTP Requests Logpush dataset; if
Worker-based logging is required instead, route asset requests through a Worker
using run_worker_first.

The hero mocks are illustrations of a fixed-size window, but on narrow screens they either reflowed into a cramped stacked layout (chat, routing map) or crushed their content (Claude Code session). They now render at a fixed 940×640 and are scaled down to the available width, so they read like a screen recording on any device. The per-mock mobile media queries are removed.
The docs delegation diagram had the same problem, plus a fallback that hid the DevSpace box on phones. It now goes through a small reusable
Fitwrapper that lays it out at 720px and scales it to its container.The landing workflow section and the docs workflow run are intentionally left alone: they are real code and status lists that stack readably, and scaling would shrink the text to illegibility.
Checked in headless Chromium at 375px, 700px/768px and 1280px; screenshots are in the comment below.
