Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Converts Minecraft Structures to Schematics

Readme

struct2schem

This package is capable of converting Minecraft structures (.nbt) to Schematics (.schem). These schematics can then be placed into a Minecraft world using tools like WorldEdit.

Usage

Below is a simple example of how this library can be used.

import struct2schem from "struct2schem";

struct2schem(structBuffer)
  .then((schemBuffer) => {
    // Do something with the schem buffer, e.g. write it to a file.
  })
  .catch((err) => console.log(err));

A more advanced example is shown below. In this example, a file containing a structure on the local file system is read (test/test_large.nbt). It is then turned into a schematic. Finally, the schematic data is written to another file (test/out.schem).

import { readFile, writeFile } from "fs";
import struct2schem from "struct2schem";

readFile("test/test_large.nbt", async (err, data) => {
  if (err) {
    console.log(err);
    return;
  }

  try {
    const schemBuffer = await struct2schem(data);
    writeFile("test/out.schem", schemBuffer, (err) => {
      if (err) console.log(err);
    });
  } catch (err) {
    console.log(err);
  }
});

Promises

This package uses promises, as processing a structure might take a bit of time. To not freeze the main thread, this operation can be done in the background. See the second example on how to use this

Limitations

There are some differences between structures and schematics. Structures are capable of having multiple "palettes", which can be seen as variants of the structure that is stored. An example of these are the shipwrecks found in the Vanilla game. The type of wood used is selected by random when the structure spawns in. This package does not support these types of structures.

Not implemented features

The following features of structures and schematics have not been implemented (yet):

  • BlockEntities, e.g. chest inventories
  • Entities, e.g. armor stands or mobs
  • Multi-palette support, see the section on limitations
