Revive React Legacy

From painful bug hunting to a royal garden.

A training to let you make legacy experience smoother.

Have you ever met a project that’s hard to grasp because of the unnecessary complexity?

Painful experience, right?

Similar to a neglected garden, React projects can become overgrown and hard to manage if owners don’t weed it out regularly.

So, when was the last time you stepped into a legacy project that's smooth and easy to maintain?

It feels like a unicorn.

For me, diving into such projects often means I struggle to learn a new structure for a couple of hours (cursing under the nose included). Not speaking of improving anything.

Muddy at first, project turns manageable after hours and hours I spend with the ugly code pass by
(there is a cleaner way, I want to show you below – more on it below).

Magic happens with refactoring

Learn to manage legacy

Most often it’s not instant action. I frequently revive the code gradually, file by file, during regular tasks.

Could the whole weeding out be smoother?

If so, how?

Who am I?

More importantly,
what's in here for you?

Grasp methods for painless work

I’ll show you proxies, feature flags and more I learned on my way.

Next, I’ll show you how to maintain legacy the easier way.

Furthermore, I’ll show you how particular TS typing that looks like overkill saves brainpower later on.

Tools to refactor

for a smoother experience

Proxies are one way to bring back the sanity. These allow to upgrade dependencies in a safer way.

• If I combine proxies with feature flags, it's way easier.
• It’s like running a marathon, but riding a taxi instead.
• It’s this level of having easier work.

Sounds good?

Another option are snapshot tests. Hyped first, laughed later, are quite forgotten nowadays.

But these protect refactoring and maintenance. Quick, cheap, easy method.

Simple, isn't it?

There's no heavy equipment and rocket science needed, really.

You can tame legacy with set of simple techniques. Methods I use in 80% of the cases.

Why should you care?

Each new feature complicates the system and makes it more like a maze. Proper maintenance is truly a relief in this case.

At the end of the day, it’s your choice to keep the legacy alive, while you develop it at the same time.

You have 2 ways:

raze part of the system and write from scratch

clean up the space

The more you mind the system on the way, the less time and energy it takes to weed it out.

Walking the first path is tempting, but there's one aspect to consider. Legacy code is the code that brings money to the company.

Is it worth risking the company's cashflow doing a rewrite?

Most often not.

Clean up sounds more time-consuming and like it needs more care, but typically, it's a safer and a more stable way.

By the way, did you know one can make most of the breaking changes in a non-braking way?

For a long time, I didn’t. It opens eyes to a world of possibilities. And programming becomes simpler when a dev grasps the concept. What’s more important, it reduces the risk of breaking stuff.

Time plays against code, and less risk is crucial in this case. More and more dependencies need an upgrade, so a dev must be careful, like a ninja in his stealth mission.

Save time and energy

Save time

A single bughunt takes dozens of minutes, sometimes hours.

Shorten it.

Properly maintained legacy means a firm way to cut off complex code.

Less complexity

Deploys can be stressful. Has your code ever introduced a bug you've missed?

Less stress

With all the above, more fun tasks open to you.

More fun

Going the second way, the dev can grasp new stuff easier. Moreover, focus and energy can go either into bug fighting or developing new skills

With proper maintenance, it's less stress for the dev and more time.

In fact, it's not about the dev only. Legacy is the code that brings money to the company. It can be either a leaky wooden cabin or the Egyptian pyramid. Pyramid brings more money to the owner.

This is a pre-order with max 100 seats available. No more.

Moreover, as it is the pre-order, to thank you for trusting me, the price is the lowest ever for this training. All future sales will be only pricier than current price. It won’t be this low again.

What's the alternative?

Dig the internet for topics about maintaining legacy projects.

Some articles could be better, some worse. How much would it take to find articles and learn what's mediocre and what's not?

You could either pay with time or join here, saving your time.

Up to you.

Did I mention it's no risk here?

You'll have up to 30 days to ask for a refund after I release the training. You could watch the whole training and then decide what to do next.

What do you think about this?

Where’s the catch?

If I wouldn't get 40 people interested in this training, I refund all orders.

Why?

Because it would mean there's low interest in such a topic. With low interest, I’d need to stretch focus on offering the program to people not interested in it. As a result, it'd take my time off polishing the training.

To sum up, it's pre-order:

for training videos (less than 2h in total).

saving you potentially dozens of hours in a year.

How much would you pay for top-notch training like this?

How much would you pay for a training that helps you:

be more competitive

save dozens of hours on hunting down bugs

maintain legacy the easier way?

There’s one more thing.

All future updates to the training are included. So, you get the knowledge early and don't miss updates on the way.
