2021-08-08 How Oj Just Got Faster
The original Oj parser is a performant parser that
supports several modes. As of this writing Oj is almost 10
years old. A dinosaur by coding standards. It was time for
an upgrade. Oj::Parser is that upgrade. It's faster and
has a cleaner option API.
2021-07-03 OjG v1.12.0 Release
MongoDB output can now be parsed by the SEN parser. Just pipe
output from mongosh to the oj application with the -mongo
option.
2021-05-23 OjG v1.11.0 Release
Not much changed in the API but the code for encoding
structs received a major performance bump. Simple type
encoding is still as fast as ever.
2021-02-22 The Pretty JSON Revolution
Wouldn't it be nice if more JSON tools supported a truly
pretty JSON format? Demand options for truly pretty JSON
now! Viva la revolucion!
2020-12-30 WebSockets with GraphQL in Go the Easy Way
With a little time over the holidays I wrote an example of
using WebSockets with GraphQL with the golang GGql
package. I've been using GGql heavily at UHN and it has
been holding up well with subscriptions and auth as well
as other layers to make mongo database integration easier.
2020-09-23 OjC vs Simdjson
Benchmarks and feature comparison with a twist. Real
benchmarks but narrated and presented as a track meet. This
goes along with the 4.0 release
of OjC.
2020-06-22 OjG Released
Oj for Go is the fastest Go JSON parser with a full JSON Path
implementation that can also be used to navigate just about any
Go data. A jq
alternative is also included for working with JSON documents on
the command line.
2020-06-09 GGql Becomes Open Source
The lawyers gave the okay to bring GGql open source. GGql
is a super fast Go GraphQL package with a much easier to
use API. GGql comes out near the top
in GraphQL
benchmarks.
2018-08-18 Agoo Release
The latest addition to my open source projects is Agoo, is a
high performance web server gem for Ruby. Agoo includes a new
publish and subscribe model that the author of Iodine and I
worked on together.
A short
article describes the API for pub/sub with some example
code.
