Freshter Logs

after many (mostly happy) hours of blood, sweat, and tears, i made a thing that lets you create append-only pesterlogs:

i made this with https://deno.com/runtime and https://fresh.deno.dev btw, i think i love deno and fresh? but they're both a touch immature. typing could also be better but it always can (gee thanks, haskell (and even haskell's type system is pretty inexpressive when it comes to dependent types (it doesn't really have them ig but yeah this is so far from relevant

dreamed that redpop was rewritten in htm/preact, breaking the majority of xkit (cool dev tool though), and also that april went on hiatus pending the reintroduction of some kind of hook into what used to be the react props, and then also the site update got pushed to prod with like 2/3 of the site missing or nonfunctional, and then also one of the dependencies of the site was a composite polymer material filled with micro machinery that did security stuff (you know, kind of like a usb security key) and the way you interacted with tumblr's desktop site was now not using a computer but rather by squeezing a small tube of goo into an empty white plastic bag of the sort used to sell soil or concrete mixes at the garden center or hardware store (that this somehow resulted in you being able to peruse media was entirely unexplained)

"was this what sreegs was talking about with that vaguepost," I thought; "I try to give the company the benefit of the doubt but I really think this cost cutting measure may have been too aggressive"

Everything About Preact & How To Use It

Preact is a lightweight JavaScript library for building user interfaces, particularly focused on creating fast and efficient web applications. It's often considered a "fast 3kB alternative" to React, another popular JavaScript library for building user interfaces. Preact shares a similar API with React, making it easy for developers familiar with React to transition. Despite its smaller size, Preact provides most of the key features found in React, making it a compelling choice for projects where performance and size are critical factors. Choosing the right framework or library can significantly impact the development process and the overall performance of your application. Preact's emphasis on speed and efficiency can be particularly beneficial, especially for projects with strict size constraints or those targeting users with slower internet connections. Preact was created by Jason Miller in 2014, a developer with a keen eye for optimizing web performance. As the name suggests, Preact is a precursor to React, maintaining the core principles of React while focusing on minimizing its footprint. Features of Preact - Lightweight: Preact's small size (around 3KB minified and gzipped) is a game-changer, especially for projects where optimizing page load speed is crucial. - React Compatibility: Preact intentionally mimics React's API, making it easy for developers to switch between the two libraries seamlessly.

Jest expect.any() not working as expected

So when testing one of my reducers in a Preact(not much different to React while testing with JEST) based project, I got bumped into this issue:

Following output comes up when running jest test -

● should setup expect(received).toEqual(expected) Expected value to equal: {"ID": Any<String>, "active": true, "data": Any<Array>} Received: {"ID": "BysnEuMlm", "active": true, "data": [{"ID": "Hy7wMAz1lm", "code": "dat.fle", "label": "CRES/datum14.cdata", "name": "File", "status": "READY", "value": {"format": "cdata", "name": "datum14.cdata", "path": "CRES"}}, {"ID": "rkB7RMkeX", "code": "prp.kcv", "label": "3 folds", "name": "k-Fold Cross-Validation", "status": "READY", "value": "3"}, {"ID": "ByCmRfygQ", "code": "ats", "label": undefined, "name": " Best First + Cfs Subset Eval", "status": "READY", "value": {"evaluator": {"name": "CfsSubsetEval"}, "search": {"name": "BestFirst", "options": ["-D", "1", "-N", "5"]}, "use": true}}, {"ID": "HkmVAM1l7", "code": "lrn", "label": undefined, "name": "Naive Bayes", "status": "READY", "value": {"label": "Naive Bayes", "name": "bayes.NaiveBayes", "use": true}}], "output": {"format": "pipeline", "name": "jestReact.cpipe", "path": "/home/rupav/opensource/candis/CRES"}} Difference: - Expected + Received Object { - "ID": Any<String>, + "ID": "BysnEuMlm", "active": true, - "data": Any<Array>, + "data": Array [ + Object { + "ID": "Hy7wMAz1lm", + "code": "dat.fle", + "label": "CRES/datum14.cdata", + "name": "File", + "status": "READY", + "value": Object { + "format": "cdata", + "name": "datum14.cdata", + "path": "CRES", + }, + }, + Object { + "ID": "rkB7RMkeX", + "code": "prp.kcv", + "label": "3 folds", + "name": "k-Fold Cross-Validation", + "status": "READY", + "value": "3", + }, + Object { + "ID": "ByCmRfygQ", + "code": "ats", + "label": undefined, + "name": " Best First + Cfs Subset Eval", + "status": "READY", + "value": Object { + "evaluator": Object { + "name": "CfsSubsetEval", + }, + "search": Object { + "name": "BestFirst", + "options": Array [ + "-D", + "1", + "-N", + "5", + ], + }, + "use": true, + }, + }, + Object { + "ID": "HkmVAM1l7", + "code": "lrn", + "label": undefined, + "name": "Naive Bayes", + "status": "READY", + "value": Object { + "label": "Naive Bayes", + "name": "bayes.NaiveBayes", + "use": true, + }, + }, + ], + "output": Object { + "format": "pipeline", + "name": "jestReact.cpipe", + "path": "/home/rupav/opensource/candis/CRES", + }, }

Following is the test case:

test('should setup ', () => { const state = documentProcessor( undefined, { type: ActionType.Asynchronous.READ_SUCCESS, payload: dokuments.active }) // expect(state.active.ID).toEqual(expect.any(String)) - Test case passes iff I run this test with this command only. expect(state.active).toEqual({ data: expect.any(Array), active: true, ID: expect.any(String), })})

Since state gets changed while calling that reducer, I needed to use expect.any function, but as per the output, although types are same, test is not getting passed.Rather in expected its showing up Any<String>.

LIST OF TOP 11 BEST FRONT-END FRAMEWORKS FOR WEB DEVELOPMENT

Front-end frameworks are extensively used in web development by IT organizations. A front end, as its name suggests, has to do with how a website or application appears to users. A substantial portion of the web design and development process involves front-end frameworks. These frameworks determine the web apps' aesthetics, visual appeal, and UX design.

Best Front-End Frameworks

1. React

2. Semantic UI

3. Angular

4. JQuery

5. Vue.Js

6. Backbone.Js

7. Ember.Js

8. Svelte

9. Foundation

10. Preact

Why Do We Choose React As Our First Preference?

React is a well-liked and flexible toolkit for building complex online apps. Because of its component-based architecture, it is simple to write reusable, modular code and complex, massive applications that take use of virtual DOM and quick rendering.

What Is Web Framework?

Web frameworks are resources that developers can use to access libraries, structures, and tools more quickly when developing web applications. Although frameworks limit some development customization, they still let programmers create the foundation for it wherever it is required.

What Are Front-End Frameworks?

For the development of websites and web applications, front-end frameworks provide a predetermined structure and design. It involves designing user-friendly user interfaces and skillfully displaying user data on the back end. These HTML, CSS, and JavaScript file sets have already been created. Additionally, offer pre-built elements and features that can be quickly customized and incorporated into a project, which increases the likelihood that a front-end interface will actually be developed.

All of these front-end frameworks have benefits and drawbacks, and they perform well for specific projects and development requirements. When choosing a framework, it's important to take into account factors like project complexity, team experience level, added functionalities, and support and resource availability. The final decision for the framework will be made in light of the particular requirements and goals of your project, as well as the level of competence of the development team.

𝐓𝐨𝐩 𝐫𝐚𝐭𝐞𝐝 𝐟𝐫𝐨𝐧𝐭 𝐞𝐧𝐝 𝐟𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤𝐬 𝐟𝐨𝐫 𝐰𝐞𝐛 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭

The building blocks of early software development are frontend frameworks. However, many options are available when it comes to creating visually stunning apps with excellent user experiences. For your interest, we have created a list of the best frontend frameworks for 2023. Let's examine them!

𝟏. 𝐑𝐞𝐚𝐜𝐭

React was developed at Facebook to address issues with code maintainability brought on by the continual addition of features to the app. It is one of the simple frameworks to learn. Thanks to its virtual Document Object Model, React is now an open-source framework that stands out for the incredible features it offers (DOM).

𝟐. 𝐀𝐧𝐠𝐮𝐥𝐚𝐫

Angular differs from React due to its two-way data-binding functionality. Accordingly, any modifications made to the model are immediately reflected in the display, and vice versa.

𝟑. 𝐕𝐮𝐞𝐣𝐬

Vue is adaptable and helps you with a range of activities. In addition to creating online, mobile, and progressive web applications, it can easily manage simple and complex tasks. Visual DOM and component-based are two advantages that make it more compact.

𝟒. 𝐣𝐐𝐮𝐞𝐫𝐲

One of the first frontend frameworks was jQuery. Its relevance, even in the modern tech world, despite its launch date, is what makes it unique. In addition to providing simplicity and convenience.

𝟓. 𝐄𝐦𝐛𝐞𝐫𝐣𝐬

Emberjs, created in 2011, is component-based and provides two-way data binding, much like Angular. It is made to easily meet the escalating demands of contemporary technology.

𝟔. 𝐁𝐚𝐜𝐤𝐛𝐨𝐧𝐞𝐣𝐬

One of the simplest frameworks out there, Backbonejs, makes it simple to develop single-page applications. It uses a framework built on the MVC architecture.

𝟕. 𝐒𝐞𝐦𝐚𝐧𝐭𝐢𝐜-𝐔𝐈

Despite being relatively new to the world of frameworks, Semantic-UI is already well on its way to being one of the frontend frameworks most extensively used globally. It is distinguished by its simple functionality, usefulness, and intuitive user interface.

𝟖. 𝐅𝐨𝐮𝐧𝐝𝐚𝐭𝐢𝐨𝐧

It was created by Zurb and is only appropriate for the enterprise-level creation of responsive and agile websites. It includes fast mobile rendering capabilities, GPU acceleration for incredibly smooth animations.

𝟗. 𝐒𝐯𝐞𝐥𝐭𝐞

The most recent frontend framework is called Svelte. In contrast to frameworks like React and Vue, the framework has made a difference by moving the work into a compilation phase rather than the browser.

𝟏𝟎. 𝐏𝐫𝐞𝐚𝐜𝐭

Because Preact is compatible with and resembles React, developers, don't have to learn it from scratch. Because of its thin compatibility layer, developers can use pre-existing React packages.

Why I still use jQuery in 2021

I use jQuery in specific use cases. One of those use cases is landing pages.

When running advertisements on social media, native platforms etc. it’s paramount that the core behavior of the page works in every browser. We do get traffic from users using ancient browsers (IE 9 etc). Not only that but

I use all the modern jazz such as babel and esbuild, but jQuery has never failed me for this use case. I’ve recently started using it on some of my smaller sites. If the move seems backwards it’s because I’m getting older and my time is important.

I love jQuery — I usually continue to use it for small features on existing sites. I personally think you’d love something like React for jQuery landing pages. Trust me, it can drastically speed up your workflow, and with the build system you already have (Babel, etc.) it should work in al the same browsers

React is great. Used it many times. And Preact. Gatsby is great too for static site generators (although I still prefer Hugo, which I use to create the HTML for the landing pages because SEO is important too sometimes). I’ve been around the block a lot.

Also, jQuery makes possible the use of a lot of amazing JS plugins… With incredible coverage on older browsers.
