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 🙏

An API to generate mock payloads for @ovotech/castle using @ovotech/avro-mock-generator

Usage

Concept

blaise() is mostly just a chainable deepMerge, with utilities to generate messages and payloads once everything is configured.

Calling blaise() returns a new version of blaise, preloaded with the provided defaults, without mutating the parent.

examples/chain.ts

import blaise from '@ovotech/blaise';

const withAvro = blaise({ avro: { schema } });
const coffee = withAvro({ avro: { pickUnion: ['coffee'] } });
const tea = withAvro({ avro: { pickUnion: ['tea'] } });

coffee.getDefault(); // { avro: { schema, pickUnion: ['coffee']}}
tea.getDefault(); // { avro: { schema, pickUnion: ['tea']}}

Generate an Avro Message

examples/avro-message.ts

import blaise from '@ovotech/blaise';

const schema: avsc.RecordType = {
  type: 'record',
  name: '',
  fields: [{ name: 'anInt', type: 'int' }],
};
type MyType = { anInt: number };
blaise<MyType>({ avro: { schema } }).message(); // {topic: '', {anInt: 32}, [...]}

You can also override the message, either as part of the default or when calling the function

examples/avro-message-override.ts

import blaise from '@ovotech/blaise';

const schema: avsc.RecordType = {
  // [...]
};
const brewCoffee = blaise({
  avro: { schema },
  message: { value: { type: 'coffee' } },
});
brewCoffee.message({ value: { with: 'milk' } }); // {offset: 13, value {type: 'coffee', with: 'milk'}, [...]}

Generate a CastleEachMessagePayload

examples/each-message.ts

import blaise from '@ovotech/blaise'

const schema: avsc.RecordType = {
  // [...]
};
blaise({ avro: { schema }).eachMessage(); // { topic: 'aTopic', value: {} [...]}

Generate a CastleEachBatchPayload

examples/each-batch.ts

import blaise from '@ovotech/blaise'

const schema: avsc.RecordType = {
  // [...]
};
const makeMessage = blaise({ avro: { schema })
blaise.eachBatch([makeMessage()]); // {batch: { topic: 'aTopic', value: {} }[...]}

Deterministic generation

Make use of the seed options to use a deterministic random generator instead of true randomness.

Each call to .defaults() or .seed() with a seed will reset the randomness.

Running the tests

You can run the tests with:

yarn test

Coding style (linting, etc) tests

Style is maintained with prettier and eslint

yarn lint

Deployment

Deployment is preferment by lerna automatically on merge / push to main, but you'll need to bump the package version numbers yourself. Only updated packages with newer versions will be pushed to the npm registry.

Contributing

Have a bug? File an issue with a simple example that reproduces this so we can take a look & confirm.

Want to make a change? Submit a PR, explain why it's useful, and make sure you've updated the docs (this file) and the tests.

What does the name mean?

It's just a fun pun. Take a Castle, make a 'mock' version of it, and you get Bristol's Blaise Castle
