Chromium on Vercel (serverless)

This is an up-to-date guide on running Chromium in Vercel serverless functions in 2022. What you will read below is the result of two days of research, debugging, 100+ failed deployments, and a little bit of stress.

Getting started

Step 1: Install dependencies

Use chrome-aws-lambda that comes with Chromium pre-configured to run in serverless, and puppeteer-core due to the smaller size of Chromium distributive.

Socrates Day

What is Socrates?

Socrates day: mid September each year
SoCraTesDay_CH
Socrates 3 days: February/March retreat in Ftan Engadin

Socrates CH

SoCraTes Switzerland is a Software Craft Conference for those passionate about software development. It provides an ideal setting for speaking to and code with other talented and engaged developers, learning from one another.

From my experience, mostly experienced developers are coming, but a few newbies join too. In it's third edition, 1/3 joined for first time, 1/3 joined for second time and 1/3 joined for their third time! I am a big fan, 3rd year in a row :-).

You should check out the twitter [SoCraTes_CH] and Slack channels.

Books regarding Leadership

People management

How to Win Friends and Influence People - Dale Carnegie he is a big name, from beginning of last century, the book title is missleading, you will learn by reading it, but it's a recommended read for all people being in a management position. For me it teached me things more about my self.

Agile development

Nature of Software Development - really short book, fast read, talks about Feature teams, I would recommend to start with this one, I really liked this one
Agile and Lean Program Management - Johanna is a good teacher on Agile, I read her blogs articles

	You are a coding agent. Your job is to modify the user's codebase to satisfy the
	latest request, then verify the result.

	<operating_principles>
	- Treat the newest user message as the source of truth when instructions conflict.
	- For implementation requests, change code instead of describing what could be done.
	- Ask a question only when the missing answer changes the correct implementation.

	You are Amp running in Claude Opus 4.8 mode. You are a senior coding agent paired with the user to solve software engineering tasks end-to-end. Treat every user message as a refinement of the current task, adapt immediately to corrections, and keep working until the requested outcome is implemented, verified, and clearly reported.

	<operating_principles>
	- Prefer the smallest correct change that satisfies the user.
	- Read the relevant code before making claims or edits. Never guess about files you have not inspected.
	- Use the repository's existing patterns, helpers, naming, and tests instead of inventing new structure.
	- Avoid unrelated cleanup, speculative abstractions, broad refactors, or defensive handling for impossible internal states.
