Serialize empty object as empty object instead of empty array with Symfony serializer

The Symfony serializer now for long had the logic that any object without values will be serialized to an empty array. The problem here is for the frontend when they expect an object. For example they might have a Typescript interface like the following: interface User { firstName: string; lastName: string;

Disable change on scroll for number field with Vue

When working with inputs of type number,  it will automatically have those arrows to increase or decrease the value. What is less obvious is that the browser will also increase or decrease the value in the field if you have the field in focus and are scrolling. This is a

Copy local files to Cloudcube (Heroku) with aws cli

When migrating from an existing setup with files to an external storage like Cloudcube (which is based on S3), you already will have files in your system. Unfortunately the Cloudcube interface doesn't support working with folders or renaming multiple files. But luckily there is a cli tool which

Sum numbers in array of objects with Typescript

In the old days a simple for loop would be enough. It still is, but way more code then needed when working with arrays. When working with reduce we can create a sum for every item. In the example we have a TimeEntry interface with multiple attributes. We only care

Use flysystem with Cloudcube on Heroku

Recently I switched from a project from an usual hoster to Heroku. For the file storage we decided to use Cloudcube (because it includes a free tier we use for review apps). For the file abstraction layer we use flysystem with the flysystem bundle [https://github.com/thephpleague/flysystem-bundle] for

Send body with axios delete request

Axios doesn't support delete requests with request body with the same signature as a post request would. But it is still possible without the need of the usage of the request function. The signature is just different. // Separate config because axios doesn't support sending a request

Run script with aliases

For one of my projects I use the following script to reset my development environment database when switching branches: php bin/console doctrine:database:drop --force php bin/console doctrine:database:create -n php bin/console doctrine:database:import dump.sql php bin/console doctrine:migrations:migrate --no-interaction Simple enough.

Set login path for Vagrant ssh

When working with vagrant and logging into the VM with vagrant ssh, you will start in the usual home directory of the vagrant user. But in a usual project you want to start in the root of your project. One option to achive this is to add extra arguments to

Import database from dump with Doctrine and Symfony

There are tickets where you have to import a database over and over again. For this it's awesome if you have some kind of automation going. Turns out there is one so easy in Symfony that you don't even think of it. A simple Symfony console

Order by list with Doctrine

Ordering by values is super simple with Doctrine with build in functionality. But have you tried order by a specific list of statuses? Without having every status assigned a number and the number stored in the database? There is a function in MySQL that can do this. It's

Working with forms and Vuetify

Vuetify is a great component library, but it doesn't really guide you through the Javascript or Typescript part. I usually use Typescript and found a good way to handle forms throughout all components. It all start's with an interface: export interface FormDefinition { valid: boolean; fields: { [key:

Restore mac app from Dock through App-Switcher

I like my desktop background, but I don't really see it ever, because I don't close apps and I don't minimize them, as I'm switching between my apps with the app switcher and not with the dock. And switching this way to

Show environment variables in Symfony

Environment variables can be defined in multiple files and you might need to check a few to see what is used at the moment. Much easier is running the following command to show all environment variables used in the currently used environment with: php bin/console debug:container --env-vars Or

Configure HTML Purifier Cache directory

HTML Purifier is a great library for sanitization. It just has a somewhat strange default setting when it comes to caching. It uses an internal cache for the structures it analyses and dumps the cache into files on the disk. The strange thing is the default path if you don&

Get global symfony kernel parameters

Recently I needed to inject the current environment into a service, but couldn't remember how the parameter Symfony offers for it was named. Luckily you can output the existing parameters on the console. And it makes it easier if you remember that it was something with "kernel&

You might not want to use entity manager / repository in a Doctrine migration

But why? It's so appealing. The simple answer: You're going to loose the opportunity to run the migrations from the beginning. Let me explain: Usually you're able to put your initial database schema in the initial migration and with every change, create a new

Escape percent sign in PHP sprintf

Why would anybody need to know that? For me it's using it in a sql query in combination with a like request. The simple solution: Use two of them. $likeQuery = sprintf(' SELECT * FROM `user` u WHERE u.roles LIKE "%%%s%%" ', User::ROLE_ADMIN); Which

Psalm Collection annotation for Doctrine

Psalm is an awesome tool for code quality. What I didn't get for a while was how to annotate Doctrine collections. First I used the array syntax, but then I found a better way. /** * @var User[] */ private $users; The first solution/** * @return User[] * @psalm-return array<int, User&

Query for JSON list in MySQL with Doctrine

Working with JSON is not as easy in MySQL as in other databases. But even in MySQL there are ways to add more complex queries through Doctrine. In this example we have an entity Change with a details field of type JSON in the database in MySQL and array in

Improve security when working with JWT and Symfony

Using JWT for authentication in a SPA with Symfony is very easy thanks to bundles like FOSUserBundle, LexikJWTAuthenticationBundle and JWTRefreshTokenBundle. Unfortunately they don't provide security against XSS attacks (which you can argue isn't really there purpose). In this post I want to show how we can

Composer tools

Recently I had an issue where I switched packages and realized only in production, that a package I use was only available in dev as a dependency and was now missing. Now I found a way to prevent this in the future. There is a tool called composer-require-checker which would

Calculate last day of month with PHP and DateTime

There are multiple options to calculate a the last (or first) day of a month. The most readable I found is the following for the current month: $lastDayOfCurrentMonth = new \DateTime('last day of this month'); $firstDayOfCurrentMonth = new \DateTime('first day of this month'); We only need

Prevent XSS through Content-Security-Policy

The Content-Security-Policy is a great little step to improve your XSS protection. In short you can define which content is allowed to be loaded through with channel. This can be added as a header in your backend like a Symfony API or directly configured in your apache config. While the

Download file through Typescript / Javascript

When working with JWT a few things get a little bit trickier. One of the examples is downloading a file through an API. When working with sessions, you can just open a link in a new tab and as long as it's on the same domain you can

Composer package not installed

Recently I switched from jms/serializer to symfony/serializer. While developing, everything worked great, but on deployment on the live system the error "phpdocumentor/reflection-docblock" not installed appeared. Not a message you want to see on your live system. When running composer require phpdocumentor/reflection-docblock, I only got
