TIPS, INSIGHTS AND THE LATEST FROM THE EXPERTS BEHIND CAKEPHP

CakeFest Insider

In case we haven’t reminded you enough lately, CakeFest 2020 is less than a month away. While we have recently hosted a few virtual meetups, a fully virtual conference is uncharted territory for our team. I like to look on the bright side of things, so I will say how excited I am that bakers from all over the world will be able to join in and participate this year. Obviously, with international travel, this hasn’t always been the case for individuals.

So my last CakeFest blog, I went into details of what to expect, and how the conference will (hopefully) run - smoothly. However, we’ve had a lot of emails and interest in hearing about what topics will be covered. Our lineup is excellent this year - so we wanted to share some things to look forward to:

 

SPONSORS

First, we have to give a shout out to this year’s sponsors

Cake Development Corporation 

Passbolt

Mark’s Software 

RingCentral

Companies that support Open Source are essential for our communities to move forward and grow! 

 

SCHEDULE

Day 1 will feature our popular workshops. These sessions are different than normal conference talks because they are basically training sessions to help grow your recipe book. You can see examples of previous years HERE. There will be basic workshops, as well as advanced during the full day session. We have condensed this year’s duration, so what is normally 2 days of workshops will be done in 2 hour sessions by each baker.  Mark Story, Jorge Gonzalez, and Jose Lorenzo are back. This year, we’ve also recruited another core member, Mark Scherer… you may be familiar with Mark from hosting many of our virtual meetups. 

Topics that our core members MIGHT include are (these are being discussed):

CakePHP 4.x, as well as project examples -  a repost builder, a headless micro cms, a media server to upload/download cache files from S3. The speaker’s will build through a project with you, answering questions as they progress. 

Have an idea you’d like the workshops to include? Email us! Cakefest@cakephp.org.
 

Now, day 2.

This year, we decided to go ahead and try a few new things. Of course being 100% digital, condensing times, and some topics and speakers that may be unexpected. I personally invited some speakers that I thought could bring something fresh to the tech conference table.  One of these being OSMI (Open Source Mental Illness). I wanted to bring mental health importance to light, and this group is doing amazing things for the development world. Mental health doesn’t have to be a taboo subject. Dr. Jennifer Akullian will be talking about mental health, stress, and burnout in the tech industry. In addition to an overview of the research, distinctive considerations of the industry we work in will be discussed, as well as how to improve the management of common stressors in technology during an incomparable time in the world.

We will also hear how some people got their start, like Michael Hoffman, and learn how to build solid architecture with CakePHP Plugins thanks to Ed Barnard. Ever wondered how to release your own plugin? Jose Gonzalez will shed some light. We are also delighted to have one of our involved Japanese community bakers, Junichi Okuyama, joining us as a speaker this year talking about helpful tips that he has learned for baking with CakePHP. Our keynote will be given by our diamond sponsor representative from Passbolt, Remy Bertot. 

Other talks will include: well known podcast host Cal Evans talking about all of the cool things that can be done with PHP's built in DateTime math, Mariano Iglesias,  core members Mark Story, Chris Nizzardini and Mark Scherer. Popular contributors Juan Pablo Ramirez and Nicolas Masson will join us and share more details about CakePHP fixture factories.  

You can see the full schedule HERE, and plan your attendance accordingly. 
 

SLACK CHATS 

We will also have slack chat rooms for attendees. This will give everyone the opportunity to interact with other watchers as well as speakers. Questions are welcomed before, during, and after the event. We will have team members monitoring the chat and trying to get all questions answered as soon as possible.  

Slack channel tag: #cakefest 

So basically, have a coffee and a chat with other attendees and presenters.

CakePHP Upgrade to 4 - Piece by Piece

Let's imagine you have a huge application in CakePHP 2.x (or 1.x) and you're planning to upgrade to the latest CakePHP 4.x. After doing some estimations, you realize the upgrade process is out of your scope, because you don't have the budget or developer availability to do it in 1 shot. At this point, some companies would abort the upgrade and keep working on 2.x for "some more time" until "this last release is delivered" or until "budget is available next fall", digging deeper and deeper into the rabbit hole…   There's an alternative you could follow if this is your case: proceed with the upgrade of a smaller portion of your application and let the 2 versions coexist for some time.   Warning: This is NOT for every project or company. Please carefully think about this decision as it has overhead you'll need to handle.   So, if your application has a portion that could be extracted, with a small set of dependencies from other areas of your application, or if you are creating a new feature with a limited set of dependencies with the rest of your application, this approach would be good for you.   In order to allow both applications to coexist, we are going to keep the CakePHP 1.x application as the main one, and use CakePHP 4.x as a subfolder inside of the first one. It's important to note that in order to share sessions between both applications you'll need to use a storage you can actually share, like database or cache based sessions (redis, etc). Then, you can use a configuration like this one (see below) to add a new upstream to handle your new application. Note: the upstream could be located in another server of your network, using a different PHP version etc.   We've used nginx as an example, but you can use the same approach in other web servers like Apache.   In our example we're going to use all paths starting with /api  to be managed by our new CakePHP 4.x application. upstream cake4 {      # Note this could be any server/port in your network where the cake4 application is installed          server 127.0.0.1:9090; }   # This is our CakePHP 2.x server server {     server_name example.com;       root   /var/virtual/example.com/app/webroot;     index index.php;       # All requests /api are forwarded to our CakePHP 4.x application location /api {         proxy_pass http://cake4;             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;         proxy_set_header Host $host;             proxy_http_version 1.1;         proxy_set_header Upgrade $http_upgrade;             proxy_set_header Connection "Upgrade";     }       location / {             try_files $uri $uri/ /index.php?$args;     }       location ~ \.php$ {           try_files $uri =404;           include fastcgi_params;                fastcgi_pass unix:/run/php/php7.4-fpm.sock;           fastcgi_index index.php;             fastcgi_intercept_errors on;         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;     } }   # This is our CakePHP 4.x server server {     listen 9090;     server_name example.com;       root   /var/virtual/cake4-example.com/webroot;     index index.php;       location / {         try_files $uri $uri/ /index.php?$args;     }       location ~ \.php$ {         try_files $uri =404;             include fastcgi_params;         fastcgi_pass unix:/run/php/php7.4-fpm.sock;             fastcgi_index index.php;         fastcgi_intercept_errors on;             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;     } }   As you can see, we have 3 blocks defined in our configuration file:

  • upstream cake4 {...} to forward requests to the CakePHP 4.x application
  • server {... 2.x ...} using a location /api to forward all these calls to the CakePHP 4.x server
  • server {... 4.x ...} using a specific port (9090) to handle requests in CakePHP 4.x
  Using this approach, you can break your application into 2 parts, and start moving features by path to CakePHP 4. You'll need to handle the changes in 2 projects for a while, and pay this overhead,  but this could be better to maintain than a CakePHP 2.x application sitting on an old PHP version. Happy baking!  

Dependency Injection with CakePHP

Dependency Injection is some of the bigger buzzwords in PHP frameworks.  Historically, CakePHP application logic didn’t support that, until the version 4.2 was released last December. You can do that on your own and have a few plugins for that. This is a new chapter of the framework, let's see how to bake it.  

Use Case

First, let’s talk about a classic Use case on real applications. Our application will include an address form, such as the shipping address for an online order, or provide information about User, Company, etc. Autocomplete can help users supply the details.   We will use the Geocoding API from Google Maps Platform, making a HTTP request for API with json output format and address parameter: https://maps.googleapis.com/maps/api/geocode/json?address=89104&key=****** And here we go, we will get this result:  

Baking a Address Service

After seeing the Use case, all we need on our backend is to make a HTTP request for API and return the JSON result for the frontend to populate related fields.   1. First, let’s exposing our application for accept “.json” requests:   2. Now, we can bake a Address Controller and let’s request an empty result: $ ./bin/cake bake controller Address --actions index   Now our app requests /address.json will return an empty JSON.   3. Let’s bake (manually) the Address Service:   Basically I’m using Cake\Http\Client to make the API request. Also I read Geocode.key from Cake\Core\Configure, we don't want to expose our key on public requests (add the key on config/boostrap.php).   4. Let’s rewrite our Controller:   5. Finally, let’s add our Service on Application.php:   That’s all bakers! Now our endpoint /address.json will support query parameters and return the result of the API request.  

The cost of shiny

I’m here selling an idea and I don't start with the cons. Unfortunately, the Dependency Injection container is an experimental feature that is not API stable yet.  The support is a bit limited, CakePHP will inject services into: constructors of Controllers and Commands and Controller actions. The core team hopefully stabilizes the feature on version 4.3, or at most 4.4. They need your help testing and finding cases, and feedback always is welcome.   I hope this post can be useful for you and your projects.  See you next time!  

Planning For Your Upgrade

Having a successful upgrade implies not only upgrading the code itself, but also identifying the different tasks that will be part of the Upgrade Plan. Making a good plan for an upgrade requires identifying the current status of the application. A good plan is based upon clear, well-defined, and easily understood objectives.   After years of experience with CakeDC making upgrades, migrating applications from CakePHP 1 to CakePHP 4 in all possible combinations, we have noticed there are a set of elements or characteristics that are useful to evaluate and identify before starting the upgrade. Having a clear understanding of these elements will be helpful to define the different tasks that will be included in the Upgrade Plan, and reduce any risk while upgrading and delivering.   Imagine that you want to run a marathon - but before starting any of the thousands of plans you can find on the internet about “How to run a Marathon”, you must know where you are. You could ask yourself:  How many miles per week are you currently running? What is the base training needed to start this program? What is the distance of your longest run in the past 3 weeks? How many days per week do you have available to exercise?, etc. This will help you to choose the plan that better fits you. It’s important to identify where you are, where you want to get and how to get where you want.    Wondering how  to evaluate where you are for the Upgrade? Evaluate the status of your application. You could consider the following points as reference:

  • What is your current CakePHP version? 
  • Identify the weaknesses and the strength of the current code by making a code review.
  • Identify the versions of the packages, plugins, libraries that your application is using. 
  • If you are using CakePHP Third Party plugins, figure out if those plugins have already been upgraded.
  • Identify any third party integration and how the upgrade could affect it. 
  • What is the unit test coverage, if any? 
  • Is there any existing documentation?
  • Is there any custom change in the CakePHP core? (I hope there is not!)
  The complexity, time, cost, and resources required to upgrade your application will depend on the status of your application. Once you know where you are, it’s the time to plan how to get where you want.  Let’s talk about this in a future article. In case you are looking for some guidance on preparing your Upgrade Plan, don’t hesitate to contact us, we could help you to identify your current status, define the plan and execute the whole plan for you. We can also work together with your team on the upgrade, helping them understand the upgraded codebase so you can maintain the project with your own team as you did before.
