Composer package development

Introducer

I don’t need to introduce the composer management package too much. I think you all know it. Some time ago, I published the composer package to the intranet hosting platform. Today, I have time to try to publish it to packagist and sort out the records.

Preparation

The preparation is very simple. There are two points in total

1. Create a new project in GitHub to manage the code of the composer package
2. Register an account with packagist and use GitHub account

Development

Make a simple demo

1. Clone the project in GitHub to local
2. implementcomposer initCommand to initialize. If there are other dependencies, you can configurerequireandrequire-devparameter
3. It will be created after the previous stepcomposer.jsonThe document can also be modified directly if it needs to be modifiedcomposer.json
4. Next, write a simple function to createsrc/helpers.php, the code is as follows

<?php

function init()
{
    echo 'test composer';
}

1. Finally, we need tocomposer.jsonThe loading method is defined in. For the loading mechanism, see this article. Because demo is relatively simple, usefilesThat’s it, eventuallycomposer.jsonas follows

{  
    "name": "test/test-composer",  
    "description": "test",  
    "type": "library",  
    "require": {  
        "php": "^7.2"  
  },  
    "license": "MIT",  
    "authors": [  
        {  
            "name": "test",  
            "email": "[email protected]"  
  }  
    ],  
    "autoload": {  
        "files": [  
            "src/helpers.php"  
  ]  
    }  
}

Release

1. Don’t forget the version numbergit tag v1.0.0
2. Push code to GitHub and tag to pushgit push origin --tags
3. Click submit on packagist platform, fill in the address of GitHub project, and click Check
4. You can use it latercomposer requireInstall the package just released
5. Packagist will update automatically when the code is submitted to GitHub later. If there is no update, please refer to this article for configuration

epilogue

It’s a very simple demo, and it doesn’t writephpunit, mainly to be familiar with the next process It is very important.
