|

|
|
<p>Application composition may lead to microservices -- which is good -- but
|
||
|
|
microservices require some ideas about how applications "talk" between them
|
||
|
|
over the wire (protocols and such) which you don't need to start with.</p>
|
||
|
|
<span id="continue-reading"></span>
|
||
|
|
<p>Again, because you just want to simplify your work, you can make the
|
||
|
|
applications use files directly: Have your first application generate two
|
||
|
|
files and the second application receive the file names from <a href="/books/things-i-learnt/command-line-options">the command
|
||
|
|
line</a>. There, simple and stupid,
|
||
|
|
and works.</p>
|
||
|
|
<p>You can even make the first application, instead of generating a file, just
|
||
|
|
send its result on the standard output, and have the second application
|
||
|
|
receive the data from the standard input -- both of which are managed as
|
||
|
|
files, anyway. Then, with a bit of magic, you can put everything together
|
||
|
|
without wasting space.</p>
|
||
|
|
<p>Worry about talking over the wire later, when you understand how networks
|
||
|
|
work.</p>
