<p>One thing you must learn is how to break your project into smaller libraries, |
|
to avoid doing rounds to deal with "the same, but a bit different".</p> |
|
<span id="continue-reading"></span> |
|
<p>I've seen a lot of projects that use things like branches for different |
|
things. Say, you have an e-commerce page. But you also have different clients, |
|
and they all have different colours and logo. Some people would take this |
|
scenario and, using the VCS properties, use the main branch for the main code |
|
and a branch for each client, merge from main branch from time to time -- and, |
|
thus, the branches are never merged back.</p> |
|
<p>This is suboptimal, 'cause that's not how VCS are supposed to be used.</p> |
|
<p>But you can, for example, break the main code into a library/framework and |
|
have one project for each client, with their assets and you just reference the |
|
library/framework in each.</p> |
|
<p>Simple and clean.</p> |
|
<p>But stop there for a second. Although this makes the code cleaner, avoids |
|
duplication and uses a VCS in the way it was supposed to be used, you can't |
|
start this way.</p> |
|
<p>Remember that <a href="/books/things-i-learnt/future-trashing">future thinking is future |
|
trashing</a>. What you can do is actually |
|
break your project by functionality, <a href="/books/things-i-learnt/project-organization">making modules related to their |
|
data</a> and then, when you get a |
|
reasonable number of clients, you'll notice what can be reused in each, what |
|
modules make sense for one client and not for another. And then you'll have a |
|
good way to deal with those.</p> |
|
<p>One project that may appear when creating libraries is "How do I create my own |
|
library repository?" 'Cause all modern languages today have support for |
|
importing external libraries and, even if your libraries will never be out of |
|
your control, they are external to the project. So you may need to learn how |
|
to deal with this before creating the libraries. And, unfortunately, each |
|
language and build tool has its own way to manage this.</p> |
