Here’s a round-up from JUXT’s open source over the past couple of weeks.
We have released Crux as a public alpha! Crux is an "unbundled" open source document database with bitemporal Datalog queries.
We have documented some of the internal libraries in Edge. We will tweak the exact formatting, but it’s a good start to have them listed somewhere.
Production documentation was moved into a sub-section to help clarify what’s relevant to that (stressful) part of a project.
We also added lifecycle documentation, to incorporate information about how you work with Edge. This currently is about updating Edge and what happens when you modify your Edge project.
The nrepl version was bumped in the dev.nrepl setup. While I was working on that I noticed that I rather hastily chose the namespace "nrepl" for this functionality, which isn’t appropriate. "nrepl" will probably be renamed to "juxt.edge.nrepl-server" in the future, it’s an internal namespace so that’s a non-breaking change.
yada 1.3-alpha introduced a new design for authentication/authorization. We’ve started iterating on that again based on feedback from projects where we’ve tried it.
While the new 1.3-alpha auth is far more spec compliant, it doesn’t encompass all the authentication strategies you find in the wild. In particular, cookie and static authentication are points of difficulty.
We think we’ve now nailed down the general approach of processing authentications, and we’re now working out how this impacts the challenge phase of authentication.
A challenge is issued when you attempt to access a resource and you don’t have sufficient authentication.
For example, if you have basic authentication on your resource, a
WWW-Authenticate header is sent containing the option of "Basic", which your browser interprets to show you a prompt.
There’s lots more to consider for the yada 1.3 auth, and we’ll cover some of it in the next post.
We also released a new 1.3-alpha with media-type suffix support. This makes it easier to implement standards like JSON:api and JSON schema.
We’ve started a mob programming project in the Milton Keynes office called shop and the goal is to:
Show an example of a real application built on Crux and Edge
Demonstrate the benefits of bitemporal queries
We’re taking the opportunity to learn more about React, JSON schema, and hypermedia in the process of working on it.
We have roles open including some in a tier-1 investment bank in Canary Wharf, London. The project is developing a new trading portal using Clojure, Reagent and re-frame, in a banking department that values technology and doing things right. The role is open to devs, seniors and project leads, get in touch with email@example.com if you’re interested.
