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.

HDF5 WASM Tools

This package provides command-line tools for working with HDF5 files, compiled to WebAssembly (WASM).

These are redistributions of tools originally provided by The HDF Group as part of the HDF5 library, compiled to WASM for use in JavaScript environments.

This package is part of the larger libhdf5-wasm project which provides WASM-compiled HDF5 libraries for re-use in other projects

These tools have no system dependencies:

statically linked to a WASM-compiled version of the HDF5 library
do not require a system installation of HDF5 to run.

Requirements

Node.js or Bun runtime
Note: Deno is not currently supported

Installation

npm install hdf5-wasm-tools

Usage

After installation, the tools can be run directly from the command line, e.g.

npx h5dump myfile.h5

npx h5repack -f GZIP -l 5 input.h5 output.h5

Compression Filters

Built-in Support: GZIP and SZIP compression filters are compiled in and available by default.

Additional Filters: To enable support for additional compression filters (such as LZF, Blosc, etc.), install the companion package h5wasm-plugins :

npm install h5wasm-plugins

Once installed in the same project, the tools will automatically detect and use the available compression filters.
