When demoing Hyperview to new engineers, there’s one comment that frequently comes up about the HXML data format: “XML, really? It’s bloated and outdated. Why not use JSON? It’s the future.” These comments imply that JSON is the “one true file format” that should be used for everything, but we don’t believe there’s such a thing. Each format makes tradeoffs in encoding, flexibility, and expressiveness to best suit a specific use case. The author makes a pretty solid argument that JSON is better for lists, while XML is better for trees.

JSON formatted files are readable to humans but the lack of comments decreases readability. With JSONC, you can use block (/* */) and single line (//) comments to describe the functionality. Microsoft VS Code also uses this format in their configuration files like settings.json, keybindings.json, launch.json, etc. This is a Go-only implementation, but the concept is portable to any language (hint, hint).

A HTTP based JSON storage. It lets you store, read & modify JSON data over HTTP APIs for FREE. Ideal for small projects, prototypes or hackathons where you don’t have to spin up your own data store. Please don’t store anything mission critical here, but like the quote above says this could be a nice option when you just need a place to temporarily dump some data you’re working with. Simply grab a BOX_ID from the homepage and then POST away: curl -X POST 'https://jsonbox.io/$BOX_ID' \ -H 'content-type: application/json' \ -d '{"name": "Schrute", "position": "Assistant (to the) Regional Manager"}'

The Couchbase team did a great job putting together this fairly-reasoned analysis. It gives side-by-side comparisons of Postgres’ JSON query syntax and SQL++/N1QL, which is the query language used in Couchbase. It touches on indexes, performance, ergonomics, and finally where each is a good fit. I’ve personally found that Postgres’ JSON data types provide just enough document-orientation that I can sprinkle in where it makes sense in our data models. But, as with all things in developer-land, YMMV!

This looks great for quickly seeing the structure of a JSON object without all the scrolling. Pretty cool that the output is valid JS so you can copy/paste it to other places as well.

JSONPlaceholder is a free online REST API that you can use whenever you need some fake data. It’s great for tutorials, testing new libraries, sharing code examples, … It comes with a set of 6 common resources. You know, the usual suspects like /posts and /comments. Prefer to use your own data? The whole thing is powered by json-server, which will get you up and running in 30 seconds-ish.

This is an excellent post with some immediately useful takeaways (and some open source, to boot). Chris starts it with a compelling description of JSON API’s value proposition: how to use JSON API as an “anti-bikeshedding weapon” Building Restful APIs requires hundreds of tiny decisions, which is like having a bike shed on every corner. Outsource the little stuff!

Transforms JSON into discrete assignments to make it easier to grep for what you want and see the absolute ‘path’ to it. It eases the exploration of APIs that return large blobs of JSON but have terrible documentation. Also works in reverse, so you can turn your filtered data back in to JSON.

To display a tweet properly, it needs to be well formatted. This means identifying and linking entities like usernames, hashtags and URLs. In simple terms, it is converting a typical tweet object like this… It is dizzying how complex the tweet data structure has become over the years. We’ve come a long way from 140 characters of unicode.

Imagine a JavaScript app that keeps all of its state in model objects. Now imagine that those objects are automatically synced and merged across network-attached devices. That’s Automerge in a nutshell. It works a lot like Git, really, except for one big difference… no merge conflicts to resolve!

The Netflix team managed to squeeze out some huge performance improvements over Active Model Serializers: We want to ensure that with every change on this library, serialization time is at least 25 times faster than Active Model Serializers on up to current benchmark of 1000 records. At first glance I thought this was a drop-in replacement for AMS, which would’ve been epic, but it has its own API. That being said, its API is pretty similar and looks easy to use. Exactly how much faster is this library? It can serialize 250 records in 3.01 ms vs AMS’s 138.71 ms!
