&lt;p&gt;In 2026, building edge-native serverless backends has become the modern standard. This guide dives into why &amp;ldquo;Hono + Cloudflare Workers&amp;rdquo; is a powerful stack, how to initialize a project, and includes a TypeScript API example.&lt;/p&gt;
&lt;hr&gt;
&lt;h2 id="1-why-choose-hono-and-cloudflare-workers"&gt;1. Why Choose Hono and Cloudflare Workers?
&lt;/h2&gt;&lt;p&gt;Traditional web frameworks (like Express or NestJS) were designed before modern Web Standard APIs emerged. Consequently, they bundle node-specific polyfills and runtime code, making them too heavy for lightweight serverless nodes.&lt;/p&gt;</description></item><item><title>Is Shared Hosting Obsolete?

A Beginner's Guide to Edge Computing with Cloudflare Workers" /&gt;&lt;p&gt;&amp;ldquo;Building a new web service or API sounds great, but server maintenance costs and effort hold me back&amp;hellip;&amp;rdquo;
&amp;ldquo;I&amp;rsquo;m always worried my server will crash during traffic spikes.&amp;rdquo;&lt;/p&gt;
&lt;p&gt;Running a website or application means constantly dealing with physical servers. Monthly fixed costs, security updates, handling sudden traffic surges — it adds up to significant stress for developers and operators.&lt;/p&gt;
&lt;p&gt;But in 2026, a trend is rapidly gaining traction that fundamentally changes web development: &lt;strong&gt;edge computing (serverless)&lt;/strong&gt; — running programs without traditional hosting — and the leading platform is &lt;strong&gt;Cloudflare Workers&lt;/strong&gt;.&lt;/p&gt;</description></item><item><title>WordPress Too Slow? 5 Proven Steps to Score 90+ on PageSpeed Insights</title><link>https://netguide.jp/en/web/webpage-speed-up/</link><pubDate>Mon, 05 Jan 2026 07:00:00 +0000</pubDate><guid>https://netguide.jp/en/web/webpage-speed-up/</guid><description>&lt;img src="https://netguide.jp/img/thumbnail/webpage-speed-up-en.png" alt="Featured image of post WordPress Too Slow? 5 Proven Steps to Score 90+ on PageSpeed Insights" /&gt;&lt;p&gt;&amp;ldquo;Spent hours writing a great article, but it loads so slowly nobody reads it&amp;hellip;&amp;rdquo;
&amp;ldquo;PageSpeed Insights shows a red score on mobile — embarrassing.&amp;rdquo;&lt;/p&gt;
&lt;p&gt;Site speed is not just about comfort — Google uses page load speed as a &lt;strong&gt;ranking factor (SEO)&lt;/strong&gt;. A slow site hurts both user experience and search visibility.&lt;/p&gt;
&lt;p&gt;&amp;ldquo;Speeding up a site sounds like engineering work.&amp;rdquo; Not necessarily. With the right plugin settings and a few image tricks, anyone can dramatically improve speed.&lt;/p&gt;</description></item><item><title>Can't Access Certain Sites?

&amp;ldquo;My blog is showing a &amp;lsquo;502 Bad Gateway&amp;rsquo; error!&amp;rdquo;&lt;/p&gt;
&lt;p&gt;If multiple sites are down simultaneously, it could be a &lt;strong&gt;Cloudflare outage&lt;/strong&gt;. Cloudflare handles nearly 20% of global web traffic — it is a massive intersection on the internet. When an incident occurs here, countless sites become unreachable worldwide.&lt;/p&gt;
&lt;p&gt;This guide explains how to check if Cloudflare is experiencing an outage and what steps both users and site administrators should take.&lt;/p&gt;</description></item><item><title>Nov 18, 2025: Massive Cloudflare Outage Took Down X, ChatGPT, Discord — What Happened?</title><link>https://netguide.jp/en/web/cloudflare-incident-2025-11-18/</link><pubDate>Wed, 19 Nov 2025 06:00:00 +0000</pubDate><guid>https://netguide.jp/en/web/cloudflare-incident-2025-11-18/</guid><description>&lt;img src="https://netguide.jp/img/thumbnail/cloudflare-incident-2025-11-18-en.png" alt="Featured image of post Nov 18, 2025: Massive Cloudflare Outage Took Down X, ChatGPT, Discord — What Happened?" /&gt;&lt;p&gt;&amp;ldquo;Last night the internet suddenly stopped working&amp;hellip;&amp;rdquo;

&lt;p&gt;Here is the timeline, the surprising cause, and what we can learn from it.&lt;/p&gt;
