From Milliseconds
 to Millions: A Look at the Numbers Powering Web Performance

From Milliseconds
 to Millions: A Look at the Numbers Powering Web Performance
By Harry Roberts

We all know performance is big business, but how big? 

Let’s take a look at some of the numbers powering the web performance industry from both sides of the table. What do performance improvements mean for my clients, and how do we translate that into a working relationship?

GraphQL queries - type once, fail everywhere

GraphQL queries - type once, fail everywhere
By Lukas Holzer

Typed languages have already become a friend in the daily business of a web developer. As a result, typed query languages like GraphQl are more often in use and gaining popularity. Nevertheless, the full potential of a typed response has not fully evolved in our development workflow. 

To unleash the true power of a type-safe environment we want to reduce the code duplication and boilerplate to the max. To take a step even further, we want to generate the code for accessing our data in a platform-agnostic way and establishing our queries as a single source of truth. 

Now we can focus on the real business use case instead of maintaining interfaces and CRUD operations.

End-to-end File Encryption in the Web Browser: A Case Study

End-to-end File Encryption in the Web Browser: A Case Study
By Thomas Konrad

Ever thought that encrypting uploaded files in the web browser before it hits the server? Most web browsers nowadays offer encryption modules via the Web Crypto API for the encryption itself, but we’ll soon see that this isn’t enough. What about the correct cipher modes? How can we ensure confidentiality, integrity and authenticity? What about big files and limited memory availability?

In this talk, we’ll cover the following topics:

  • Issues you’ll face when implementing end-to-end file encryption in the browser
  • The crypto basics behind file and metadata encryption
  • The Web Crypto API
  • The FileReader API for chunked uploads
  • The ReadableStream API for chunked downloads
  • Service Workers and how they’ll help us
  • Browser compatibility of the mentioned APIs
  • What we can do to support older browsers
  • The hardest part: key distribution
