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 🙏

Norsub eMRU Parser

npm (scoped) publish npm

Library to read NMEA-like sentences of Norsub eMRU devices. It works same as NMEA-Parser library and it has the same API. The only nuance is it gives metadata of the device status if the sentence bring that info.

To understand how it works, please look the info of NMEA-Parser library.

PNORSUBx sentences contains status property in the metada as

type Status = {
  main: {
    ok: boolean,
    health: boolean,
  },
  system: {
    ok: boolean,
    health: boolean,
    synchronized: {
      time: boolean,
      clock: boolean,
    },
    cpu: boolean,
  },
  sensor: {
    ok: boolean,
    health: boolean,
    limits: boolean,
    environmental: {
      vibration: boolean,
      temperature: boolean,
    }
  },
  algorithms: {
    ok: boolean,
    health: boolean,
    initialization: {
      observer: boolean,
      heading: boolean
    },
    roll_pitch: {
      ok: boolean,
      health: boolean,
    },
    heading: {
      ok: boolean,
      health: boolean,
    },
    surge_sway: {
      ok: boolean,
      health: boolean,
    },
    heave: {
      ok: boolean,
      health: boolean,
    },
  },
  aiding: {
    received: {
      position: boolean,
      velocity: boolean,
      heading: boolean,
    },
    valid: {
      position: boolean,
      velocity: boolean,
      heading: boolean,
      vertical: boolean,
      horizontal: boolean,
    }
  }
}

The complete output with metadata it is shown below.

type NMEASentence = {
  // Sentence ID
  id: string,
  // Array with ordered fields and their metadata
  payload: Array<{
    name: string,
    value: string | number | bigint | boolean | null,
    type: 'string' | 'boolean' | 'uint8' | 'uint16' | 'uint32' | 'uint64' | 'int8' | 'int16' | 'int32' | 'int64' | 'float32' | 'float64' | 'unknown',
    units?: string,
    description?: string,
    metadata?: any
  }>,
  // Metadata which can be computed fields from payload fields
  metadata?: any,
  // Protocol information
  protocol: {
    name: string,
    standard: boolean,
    version: string,
  },
  // UTC timestamp when the sentence was parsed
  received: number,
  // Whole ASCII string sentence
  sample: string,
  // Sentence checksum
  checksum: {
    sample: string,
    value: number
  }
  // Sentence talker
  talker?: {
    value: string,
