jackson-databind VS mustache.js

Jackson had this problem a few months back, where someone reported a critical CVE against the project and broke builds all around the planet https://github.com/FasterXML/jackson-databind/issues/3972

Basically the programmer (not the attacker) had to write code where an object contained itself

HashMap map=new HashMap<>();

map.put("recursive",map);

After this, Jackson would indeed stack overflow if you asked it to wrap the object to JSON. Then again, half the build-in Java functions (e.g. getting an object hashcode for the map object) also fail for a recursive structure.

The issue remains open 3 months later, Mitre still thinks it's hella serious, and people have yet again learned to just ignore their CI warning about CVEs

jackson-databind maintainer responds to a similar occurrence few weeks ago: https://github.com/FasterXML/jackson-databind/issues/3972#is...

As to Jackson itself see https://github.com/FasterXML/jackson-databind/issues/1970 for example on startup issues. There are others.

after reading https://github.com/FasterXML/jackson-databind/issues/2239 but setting JsonCreator and adding the JsonFormat didn't work.

Jackson should support records out of the box https://github.com/FasterXML/jackson-databind/issues/2709

Its not like this vulnerability is something new. Similar issues have been public knowledge for at least four years and discussed widely. The fact that str to int and int to str conversions are slow for huge ints is hardly news.

In C#, Newtonsoft Json has similar functionality, and in Java — Jackson2 ObjectMapper.

Templating engine: SSGs rely on templating engines to define the structure of web pages. These engines enable developers to create reusable templates and incorporate dynamic content. Popular templating engines include Liquid, Handlebars, Mustache, EJS, ERB, HAML, and Slim.

I also enjoy simple templating engines. It makes it far easier to reason about a template and mentally step-through it. For existing art, there are:

DustJS which is a "logic-less" template engine (just loops and simple if-statements): https://github.com/linkedin/dustjs

and there is also mustache, which is very similar: https://mustache.github.io/

Personally, I've re-implemented DustJS in rust but its still a very alpha project: https://code.fizz.buzz/talexander/duster

I think the homepage states, "Logic-less templates"

Other popular templating engines include Jade, EJS, and Handlebars. Jade is a high-performance templating engine that is used for server-side rendering. EJS is a lightweight templating engine that is used for client-side and server-side rendering. Handlebars is a templating language that is based on the Mustache template language.

JSX just a templating language in this case, right? No reactivity at all? What's the benefit against using something like https://github.com/janl/mustache.js/ ?

You don't have to even program the replacement part yourself, because there are many libraries made specifically for that. For this example, I'd recommend mustache.

This is one of the least-bad names because it implements a non-Boost standard and it's named after that. I've used mustache in Python so knew immediately it was a templating language.

First, I setup mustache (npm package) as the templating language (the npm package hasn’t been updated in two years, so that’s great). Mustache is really simple, it provides a few helper utilities, like replacing variables, or iterating over data,

Once the array is ready and back in place, we need to display the information from the emails, and for that we can use the template node. This node uses the mustache system, which is a logicless template engine for creating dynamic content. In other words, it generates HTML code by using tags that are replaced by code.
