Taking the Wagon
to Marketnobody buys from your barn

Nine sessions in, you have a folder, an assistant that works in it, house rules, an undo, a map and a well. And every single bit of it lives on one laptop, in one house, and is visible to one person, who is you.

That is not a criticism. It is the normal shape of things at this point, and it is where a great many people quietly stop — not because the building got hard, but because the last step never got taken and the thing slowly stopped mattering.

The gap is smaller than it looks. It is one command, or one button, and about forty seconds.

A thing nobody can reach is a hobby. That is fine, as long as you meant it.

The word cloud has done a lot of damage, because it makes something quite ordinary sound like weather. Here is the whole arrangement, and there is nothing else hiding behind it.

• A computer that never gets switched off. In a building somewhere, with better power and better internet than your office has, looked after by people whose only job that is.
• A copy of your work on it. Not the original. Your folder stays exactly where it is; a copy goes up.
• A name pointing at it, so that when somebody types the name, they arrive at your copy rather than somebody else's.

That is it. When people say a thing is “deployed”, they mean those three have happened. The word for doing it is deploy, and the machine belongs to a company — ours is Vercel, the same account you signed up for last session to get the well.

Two things worth being clear about now rather than later.

• Your laptop is not involved once it is up. You can close it, sell it, or drop it. The copy keeps serving.
• Nothing goes up that you did not send. Deploying does not scoop up your machine. It sends the one folder you pointed it at, and nothing else on the disk is in reach — the same line round the work from session three.

Not weather. A computer, in a building, that nobody ever turns off.

You would not take a green horse straight out onto the road. You work it in the paddock, then in a fenced ring where it can meet a few real things safely, and only then do you take it out where the traffic is. Publishing works the same way, and the middle step is the one nobody expects.

• The paddock — your own machine. Fast, private, and nobody else can reach it at all. This is where you have been for nine sessions.
• The training ring — a preview. Every time you send work up, it gets its own address on the real internet. Real ground: same machines, same speed, same everything. But there is a gate on it.
• The open road — production. The short address. The one you print on a van. There is only ever one of these, and it is the only one the public can open.

The habit that follows is simple and it is the whole safety story of this session: look at it in the ring before you take it on the road. Same work, same internet, on your phone, with nobody watching. Then promote it.

Real ground, with a fence round it. That is what a preview is.

Here is the demo, start to finish, and you have met every idea in it before in another form. One page of Dale's — the three jobs waiting on him — and four commands.

The rollback is the part worth sitting with. Your recent versions are still there, whole, and going back to the last good one is a choice rather than a repair. When it ran during testing it took two seconds.

That matters because of what people do otherwise. Something goes wrong on a live site at four on a Friday, and the instinct is to fix it — badly, in a hurry, while customers watch. The professional move is the opposite: put the old one back first, so nobody is watching any more, and then fix it properly on Monday.

The version you will actually use

Commands are fine for showing you what happens. What you will really do is connect the folder to your Vercel account once, and then it deploys itself.

• Every marker you push — session seven — gets its own preview address, automatically, without you asking.
• Whatever is on your main trail becomes production.
• You stop thinking about deploying. Saving a marker and publishing become the same act, which is the point at which this stops being a chore.

That is why session seven came before this one. The markers were never only an undo — they are also the thing that decides what the public sees.

Do not fix a live site under pressure. Put yesterday's back, then fix it.

The mechanics of publishing are easy, and you have just done them. What is worth ten minutes is the short list of things that are different once a stranger can reach your work.

Four things that are true from now on

• Anything in the page can be read. Not most of it — all of it. Right-click, view source, and there it is. So no keys, no passwords, no supplier prices you would not put in the window.
• The well is reached by the wagon, not by the customer. The page a customer loads never talks to your database directly. It asks the machine that serves the page, and that machine holds the key. This is the single most common expensive mistake, and now you will not make it.
• It costs nothing until it is working. Free tiers are generous, and no card is asked for. When you do outgrow them, the bill arrives because the thing is being used, which is the good problem.
• The name is separate from the thing. A domain is rented by the year and pointed at whatever you like. You can point it somewhere else next spring without rebuilding anything.

Before you close this page

The four labs are the doing. Two things are worth carrying out of here in writing.

1. Write down your short address — the something.vercel.app one — somewhere you will find it. That is your address now. Put it on the quotes, put it in the email signature, say it on the phone.
2. Write down three things about that page that must never stop being true. The phone number is on it. It loads on a phone. The price list is the current one. Plain sentences, each either true or false. #011 turns those three sentences into checks that run themselves, and arriving with them already written is most of that workshop done.

The second one is the one that matters. It is fifteen minutes of thinking, and it is the difference between a page you are proud of today and a page you can still trust in March.

The habit worth keeping: look at it in the ring before you take it on the road, and when something goes wrong on the road, put yesterday's back before you try to fix anything. Both take seconds. Both are the difference between a bad ten minutes and a bad Friday.
