Taiwan's Vue community is meeting up in Taipei on Saturday, October 17 💚

v-conf Taiwan 2026 is run by Vue.js Taiwan, and Evan You, the creator of Vue.js, is giving the opening talk on where the V ecosystem is heading

The rest of the day covers Vue Language Tools, repackaging an open-source library with tsdown, and whether you still need to learn Vue now that everyone builds with AI

📍 NCCU Public Affairs Center, Taipei
🗓 Sat, Oct 17, check-in 09:00

Full agenda: https://buff.ly/lHg20qd
Tickets: https://buff.ly/lvvfp7C

It's this month's featured event on HackMD Community, where we now list developer events alongside the notes you read: https://buff.ly/JKAUH0T

10/10/2026

When HackMD knocks, what happens next? You decide. 🚪

A note gets updated. A document gets published. A folder changes.

With webhooks, you can use those moments to trigger your next step, whether that’s notifying your team, sharing a published note, or starting an automated workflow.

Connect HackMD to your tools through a webhook receiver, and give your docs a role in moving work forward.

Watch the walkthrough and imagine what you’d automate first 👇

Your next project idea might start with someone sharing how they built theirs. 💡

Meet Ali Gamal, one of the top voices in our HackMD community.

His writeups explore projects like building a personal dashboard with the HackMD API and running an AI agent workflow through Telegram, with implementation details you can dig into yourself.

We love seeing our community turn their experiences into something others can learn from.

Your agent deserves context that keeps your team in the driver’s seat. 🛞

The decisions behind your roadmap. The reasoning behind a requirement. The things your team has already tried.

That’s context worth writing down and keeping up to date together.

Use HackMD to give that knowledge a shared home, so the context you bring to your agent reflects the people behind the project.

What’s one thing you wish your agent understood about your team?

HackMD Webhooks are live 🪝

Here's what this means:

🔔 HackMD sends a signed event when a note or folder changes, so your script can stop polling

📁 Scope a webhook to one folder and its subfolders, or the whole workspace

🔐 Every delivery is signed, and each webhook keeps a downloadable delivery log

🔀 A small receiver you control routes events to Slack, Discord, GitHub Actions, or your own API

Your tools can finally hear about a change instead of asking for one

Read the full update here:

HackMD can now send a signed event to a URL you control whenever a note or folder changes. Here is how it works, who it is for, and what to know before you wire one up.

You’ve written the docs.

Now give your team a place to read them together. 📖

With HackMD’s Book Mode, you can create a book directly from your workspace, add sections and dividers, and set permissions through your folder.

From onboarding guides to project documentation, you can add structure to your notes so everyone can follow along.

Imagine all the markdown collaboration your team can do with the new  VR Glasses. 😍

Your content workflow can stay in Markdown from draft to deployment.

Astro now has an official guide for using HackMD as a CMS. 💜

You can write and collaborate with your team in HackMD, then use the HackMD API to pull that content directly into your Astro project.

The guide walks through:

→ connecting HackMD to Astro
→ fetching your notes
→ generating pages from your Markdown
→ building a blog with HackMD as the content layer

Your team gets a collaborative place to create.

Your site gets structured Markdown ready to ship.

Your agent skills are becoming part of your team’s infrastructure.

So why are they still scattered across local folders, repos, and individual setups?

With HackMD, you can import your existing .md files into a shared workspace and give those skill files a central home your team can collaborate on and govern together.

That means your team can keep the knowledge powering your agents:

→ centralized
→ accessible to the right people
→ collaborative
→ easier to maintain as workflows change

Your skill files are more than Markdown.

They are part of how your agents understand your team.

Give them a home built for shared knowledge. 💜

Book Mode is rebuilt 📚

The knowledge your team needs is almost never in one note. It is in a dozen, and turning that pile into something readable has always been the part nobody wants to do. HackMD books could always do it. Now you don't have to memorize syntax first.

Here's what this means:

✏️ Build the book from the sidebar. Add, rename, reorder, and nest items up to three levels, with no source Markdown to hand-edit and nothing to refresh.

🖱️ Reorganize by dragging. Move items in and out of sections, or drop one item onto another to create a section around both.

🔗 Share the whole book, not one page. Shared links keep book context, and HackMD finds notes whose permissions are narrower than the book's and aligns them in one step.

Read the full update at the link below 👇

You can now add, rename, reorder, and nest everything in a HackMD book directly from the sidebar, with no Markdown syntax to memorize and no refresh to remember.
