Building kedro.dev

Follow along the Journey as I build out kedro.dev. Building a Community # I have really enjoyed my own personal journey as I have started to build all of my data pipeline projects with the kedro framework. I want to start building a place to share resources with the community. I want to see this community grow and flourish. They say in front end web development if you are not using a framework you end up building one. That’s exactly what I was doing before I started using kedro. I want to build out a set of resources that this community can learn from and start to use the framework at their own pace without needing to develop their own from scratch. research # Looking into the front end frameworks to see how they welcome their community. Much of my inspiration is from them, bringing lessons learned to data. pages # banner nav docs -> readthedocs tutorial -> kedro-examples blog -> medium community support team courses examples meetups conferences articles podcasts videos external resour…

Kedro Static Viz 0.3.0 is out with Hooks Support

kedro-static-viz is out with support for the newly released hooks feature. This means that you can have automatically deploy a full gatsby site keeping your visualization always up to date. Even though it is a static site there is no functionality lost. The only thing that’s missing is the flask server. With kedro-static-viz you can deploy your visualization to a number of static hosting providers such as GitHub pages free of charge with wicked fast performance ⚡ It’s Fast # Even though it’s built on gatsbyjs the full site builds in under 2s even on slower hardware. This is because the site is already pre-rendered and stripped of any excess. It’s zipped up right into the python package and is typically used with the cli, but now can be used with python, or as a hook as well. What is kedro-viz 🤔 # Kedro viz is a fantastic kedro plugin that allows you to visualize your data pipeline. Kedro allows you to quickly build production-ready pipelines where you just configure a catalog, then tos…

Create Configurable Kedro Hooks

There are two main ways to create kedro hooks, with modules and classes. Each one still uses the same verbiage as the function/method names. Class hooks seem a bit special as they give you a way to configure them so that they are a bit more generally useful.

Then we will install from pypi. Create a sample project # Kedro new # For more details check out my full post on kedro new For this post I really just want a working pipeline as fast as possible. For this I am going to use iris pipeline that is generated from the command in the cli. It’s important that you answer to create an example pipeline.

Four github actions for your website

GitHub’s actions are a new GitHub feature that will trigger GitHub to spin up a virtual machine and run some tasks with some special access to your repo. It can interact with comments/issues, it can clone your repo, You can explicitly pass in secrets so that it can commit back to the repo or deploy to another service. The environment may be a Linux, windows, or even a mac machine. I believe this is wildly incredible for the open-source community, putting these tools in the same place that we are already collaborating is so convenient. What can they do for my personal website? 🤔 # GitHub actions can give you confidence that your site is up and running, with the latest JavaScript packages, does not have broken links, and can even take screenshots of what your website looks like on different screen sizes and operating systems. periodically check that the website is up update npm url checker screenshot website srt32/uptime # srt32/uptime is an action that you can run on any public website.…

Create Custom Kedro Dataset

Kedro provides an efficient way to build out data catalogs with their yaml api. It allows you to be very declaritive about loading and saving your data. For the most part you just need to tell Kedro what connector to use and its filepath. When running Kedro takes care of all of the read/write, you just reference the catalog key. But what is happening behind the scenes # Under the hood there is an that each connector inherits from. It sets up a lot of the behind the scenes structure for us so that we dont have to. For the most part kedro has connectors for about anything that you want to load, csv, parquet, sql, json, from about anywhere, http, s3, localfile system are just some of the examples. Here is a DataSet implementation from their docs. Here you can see the barebones example straight from the docs. Parameters from the yaml catalog will get passed in

Interrogate is a pretty awesome, brand new, cli for Python packages

As usual while listening to python bytes 181 I heard of a tool that I had to try out right away! This thing is 🔥 hot off the press folks, we’re talking the first release only 3 weeks ago. Its something that the python community needed years ago, and it belongs in your CI today. I had tried several tools that tried to do docstring coverage in the past but they were a bit cumbersome and were quickly forgotten about. Not interrogate, its dead simple! Nothing I have tried has come close to being this good Interrogate # It runs documentation coverage for your python project. It allows you to set the minimum amount of docstring coverage for your project and has some great setup instructions right in the readme. Install it # Interrogate is on pypi so it is super simple to install with run it # This is the best part, its super easy to run right from the command line! Just call it, and give it a path to run. 😲 I have some work to do # One of my new open source packages find-kedro only hit 71%.…

drawing ascii boxes

When creating cli’s I often want some nice full-width character. I find it tough to find them, and when I do half the time it is an image or something that cannot be copied 👿. I rarely get very complex with my semi-manual ASCII art. I can do 98% of what I need with bars and corners. Using some simple full-width characters can really give your cli a nice clean look. Example # I’d say 50% of what I need is just a full-width horizontal bar to give some visual flair or separation. Bars # Square Corners # Round Corners # Harpoons # Double Boxes # Dashed Boxes # Connectors # Others # Arrows # Rounded Box # Resources # As I was putting this together I stumbled accross a good site to find ascii characters and copy them.

📢 Announcing find-kedro

is a small library to enhance your kedro experience. It looks through your modules to find kedro pipelines, nodes, and iterables (lists, sets, tuples) of nodes. It then assembles them into a dictionary of pipelines, each module will create a separate pipeline, and being a combination of all pipelines. This format is compatible with the kedro format. # is a ✨ fantastic project that allows for super-fast prototyping of data pipelines, while yielding production-ready pipelines. enhances this experience by adding a pytest like node/pipeline discovery eliminating the need to bubble up pipelines through modules. When working on larger pipeline projects, it is advisable to break your project down into different sub-modules which requires knowledge of building python libraries, and knowing how to import each module correctly. While this is not too difficult, in some cases, it can trip up even the most senior engineers, losing precious feature development time to debugging a library. # is deplo…

Explicit vs Implicit Returns in Javascript

Often when reading through javascript examples you will find some arrow functions use parentheses while others use braces. This key difference is that parentheses will implicitly return the last statement while braces require an explicit return statement. It is important to understand the difference between them because it is likely that you will find code examples of both and trying to edit code written differently than you’re used to may have unintended consequences. # Arrow functions are one-liner functions in javascript that have two main syntactical ways to create the code block. with parentheses and braces. Let’s take a look at both ways of creating arrow functions so that when we come accross them in the wild it will all make sense. # Here is an example of an arrow function that will implicitly return the last statement without the return keyword. I believe that these are a bit more restricted in that you cannot set variables inside them. They are a little bit more concise and g…

TIL: Bind arguments to dynamically generated lambdas in python

This past week I had a really weird bug in my kedro pipeline. For some reason data running through my pipeline was coming out completely made no sense, but if I manually request raw data outside of the pipeline it matched expectations. NOTE While this story is about a kedro pipeline, it can be applied anywhere closures are put into an iterable. # After a few days of looking at it off and on, I pinpointed that it was all the way down in the raw layer. Right as data is coming off of the database. For this I already had existing files stored and a function to get the data so I opted to just set up the pipeline to utilize the existing code as much as possible, leaning on the kedro framework a bit less. I have dynamically created lists of pipeline nodes many times in the past, but typically I take data from kedro input and use it in the lambda. I prefer the simplicity of using lambdas over. It typically looks something like this. What was different this time is that I needed to pass in the…

Four Github Actions for Python

If you are developing python packages and using GitHub here are four actions that you can use today to automate your release workflow.

Variables names don’t need their type

So often I see a variables inside of its name and it hurts me a little inside. Tell me I’m right or prove me wrong below. Examples # Pandas are probably the worst offender that I see Sometimes vanilla structures too! Edge Cases? # It’s so common when you need to get inside a data structure in a special way that itsn’t provided by the library…. I am not exactly sure of a good way around it. Containers are plural # Always name your containers plural, so that naming while iterating is simple. Before I start fights 🥊 in code review, am I inline here or just being pedantic?

Send Emails with GitHub Actions

Here is one useful thing that you can do with GitHub actions no matter what language you use, send email. You might want to know right away when your ci passes. You might want to give your team a nice pat on the back when a new release is deployed. There might be subscribers wanting to see the latest release notes in their inbox as soon as the latest version is deployed. Whatever it is, its pretty easy to do with an action right out of the actions marketplace. Mail on Star # Here is a silly example that sends an email to yourself anytime someone stars your repo.

What Are GitHub Actions

GitHub actions are an amazing tool that allows us to run code based on triggers inside of our repo. Their is a large and growing community of actions inside the marketplace to use with very little effort. Best of all they are free for public repositories, and private repos have a very generous free tier. I have been diving deep into Github actions for about a month now and they are wicked good! They allow you to run any sort of arbitrary code based on events in your repo, webhooks, or schedules. They are very reasonably priced. The interface that GitHub hs developed for them is top-notch! It’s so good I have done 90% of my editing of them right from github.com. TLDR # some interaction to your repository triggers code to run. # The online editor for actions is pretty amazing. When creating a new workflow it automatically sets up a new blank workflow or a workflow from the marketplace for you in your directory. This is all it takes to get an action running, a or file in the directory. Th…

Getting Started with GitHub Actions

Github actions are written in configuration files using the YAML syntax. YAML is a superset of JSON. Most YAML can be expressed inline with JSON syntax. Similar to python YAML is whitespace driven by whitespace rather than brackets tags. The argument for using YAML for configuration files such as actions is that it is more human-readable and editable. It’s much easier to see the whitespace layout than it is to get closing brackets correct. For actions, I believe this is mostly true. I don’t see any use case to get past 3-5 indents, which is completely manageable. Can I just say that I learned more than I realized about YAML by writing this article Arrays and Objects # In YAML or JSON, the most basic containers for data are arrays, a 1D list of things, and objects, for key-value pairs. Arrays # The start of an array container is signified with a leading. This is probably one of the big things I didn’t understand about YAML before writing this post, but hats off to the GitHub actions edi…

Today I learned git diff feature..main

Today I learned how to diff between two branches. Sometimes we get a little happy and mistakenly commit something that we just can’t figure out. This is a good way to figure out what the heck has changed on the current branch compared to any other branch. Example # Let’s create a new directory, initialize git and toss some content into a readme. After all of that, we have a git repository on our local machine with a single file that contains the following. Create a branch and ✍ edit # Let’s checkout a new branch called Waylon and change the word to in our file, then diff it. At this point we have one commit. Things are really straightforward, and our diff will be the same between the last commit and the main branch since. Let’s make another commit by adding the date. 👆 At this point, our diff doesn’t tell us the whole story between our current state and main, only between our current state and our last commit. Let’s commit our changes and compare our branch to main. Git is powerful # I…
