Flysystem and Silverstripe CMS

Lightning talk at StripeCon EU 2019. A quick overview about Flysystem and it's integration into Silverstripe CMS

1. Flysystem and SilverStripe I believe I could fly…? 11.10.2019 www.silverstrip.es 1
2. What‘s that? • File system abstraction library for PHP • Omnipay for files • Adapter pattern • Your code doesn‘t care if your file is saved locally… • …or on S3, Azure, Dropbox, FTP… • …just talk to the flysystem adapter 11.10.2019 www.silverstrip.es 2
3. History • Developed by Frank de Jonge (thephpleague) • v0.1 in Oct. 2013 • v1.0 in Jan. 2015 • Currently v1.0.55 • MIT licensed 11.10.2019 www.silverstrip.es 3
4. SilverStripe and Flysystem • SS4 uses Flysystem • Now it‘s easier to work with remote files 11.10.2019 www.silverstrip.es 4
5. Some Differences • Versioned Files needs a public and a private adapter • Thin wrappers around Flysystem adapters 11.10.2019 www.silverstrip.es 5
6. Adapter anyone? • Local Adapter • S3 Adapter • Many Flysystem adapters available • Need modification for SiverStripe‘s public/private files 11.10.2019 www.silverstrip.es 6
7. Configuring • The S3 Adapter only needs some ENV-Vars set: – AWS_REGION – AWS_BUCKET_NAME – AWS_ACCESS_KEY_ID* – AWS_SECRET_ACCESS_KEY* – * if outside of an EC2 instance • Injector replaces the local adapter with the S3 adapters 11.10.2019 www.silverstrip.es 7
8. Problems? • One more abstraction layer seems overkill • Updating file related code from SS3… • Know your filesystem • Injector is powerful but complicated 11.10.2019 www.silverstrip.es 8
9. Questions! • Multiple Adapters possible? • Save different DataObject relations in different file systems? • E.g. put user uploaded files to a dropbox 11.10.2019 www.silverstrip.es 9
