In our previous post, we explored the basics of the protocol buffers (protobuf) wire format. Now, let's take a closer look at some advanced features: packed repeated fields, maps and negative numbers.

Kreya has introduced a powerful new feature: HAR file import! This update makes analysing, replaying and debugging HTTP and gRPC-Web requests directly in Kreya easier than ever. In this post, we’ll show you how to export HAR files from browsers and import them into Kreya. We will also explain why this is a secure and essential workflow for developers, particularly those working with gRPC-Web APIs.

Kreya 1.17 comes with the new Kreya Script, which can control operation invocation with JavaScript. Support has been added for importing HAR files, the JWT auth provider, exporting operations as cURL and gRPCurl commands and many more features have been implemented.

Kreya 1.16 comes with support for WebSocket calls and an updated look and feel for the project settings. Faker is added to the scripting API, cookie management is added and many more features are implemented.

4 million invoked operations, over 4,700 monthly active users and 4 releases. These are some key facts about the past year.

Kreya 1.15 comes with support for protobuf editions. Operation, directory and collection paths can be viewed and copied from the tab's context menu. Comments imported with a proto file are now visible in the declaration tab.

Protocol buffers transform data into a compact binary stream for storage or transmission. In this blog post, we will use a proto definition of a sample message and serialize it to binary data.

Protobuf Editions bring a major change in the way Protocol Buffer versions are handled. Currently there are two versions, "proto2" and "proto3", and the differences between them aren't always obvious. Migrating from proto2 to proto3 isn't easy either. In this blog post we will explore how Protobuf Editions are going to improve this.

Kreya 1.14 brings you a lot of new features. Starting with running a directory as a collection, an Insomnia importer, automatic import of system environment variables and opening items in the file manager. The CLI now has the ability to invoke multiple collections with a single call and generate a JUnit test report. Scripting has been improved and trace messages can be filtered.

2.87 million invoked operations, almost 4,000 monthly active users and many more numbers that our telemetry has provided us with over the last year.
