Challenges and Opportunities
With so many choices, and such a robust and blossoming ecosystem at present, where does that leave the community? While having choices is a good thing, it can be difficult for organizations to know where to start, what they need to be successful, and why they need it. As user expectations grow for how an application should perform and behave (load faster, run more smoothly, be responsive, feel native, and so on), it gets ever more challenging to find the right balance between the productivity needs of the development team and the project’s ability to launch and succeed in its intended market. There is even a term for this called analysis paralysis, which is a difficulty in arriving at a decision due to overthinking and needlessly complicating a problem.
Chasing the latest tools and technologies can inhibit velocity and the achievement of significant milestones in a project’s development cycle, risking time to market and customer retention. At a certain point an organization needs to define its problems and needs, and then make a decision from the available options, understanding the pros and cons so that it can better anticipate the long-term viability and maintainability of the product.
At Kenzan, our experience has led us to define and coalesce around some key concepts and philosophies that ensure our decisions will help solve the challenges we’ve come to expect from developing software for the front end:
Provide a stable and mature local development environment with low-to-no maintenance (that is, no global development dependencies for developers to install or maintain, and intuitive workflows/tasks).
Adopt a single package manager to manage front-end and build dependencies.
Deploy optimized, feature-based bundles (packaged HTML, CSS, and JS) for smarter, faster distribution and downloads for users. Combined with HTTP/2, large gains can be made here for little investment to greatly improve user experience and performance.
A New Stack
Package Management: Yarn
The challenge of how to manage and install external vendor or internal packages in a dependable and consistently-reproducible way is critical to the workflow of a developer. It’s also critical for maintaining a CI/CD (continuous integration/continuous delivery) pipeline. But, which package manager do you choose given all the great options available to evaluate? npm? jspm? Bower? CDN? Or do you just copy and paste from the web and commit to version control?
Our first article will look at Yarn and how it focuses on being fast and providing stable builds. Yarn accomplishes this by ensuring the version of a vendor dependency installed today will be the exact same version installed by a developer next week. It is imperative that this process is frictionless and reliable, distributed and at scale, because any downtime prevents developers from being able to code or deploy their applications. Yarn aims to address these concerns by providing a fast, reliable alternative to the npm cli for managing dependencies, while continuing to leverage the npm registry as the host for public Node packages. Plus it’s backed by Facebook, an organization that has scale in mind when developing their tooling.
Application Bundling: webpack™
The orchestration of building a front-end application, which is typically comprised of a mix of HTML, CSS, and JS, as well as binary formats like images and fonts, can be tricky to maintain and even more challenging to orchestrate. So how does one turn a code base into an optimized, deployable artifact? Gulp? Grunt? Browserify? Rollup? SystemJS? All of these are great options that provide their own strengths and weaknesses, but we need to make sure the choice reflects our intended principals we discussed above.
webpack is a build tool specifically designed to package and deploy web applications comprised of any kind of potential assets (HTML, CSS, JS, images, fonts, and so on) into an optimized payload to deliver to users. We want to take advantage of the latest language features like import/export and class to make our code future-facing and clean, while letting the tooling orchestrate the bundling of our code such that it is optimized for both the browser and the user. webpack can do just that, and more!
Language Specification: TypeScript
What About Front-End Frameworks?
As you may have noticed, so far we’ve intentionally avoided recommending a front-end framework or library like Angular or React, so let’s address that now.
Different applications call for different approaches to their development based on many factors like team experience, scope and size, organizational preference, and familiarity with concepts like reactive or functional programming. At Kenzan, we believe evaluating and choosing any ES2015/TypeScript compatible library or framework, be it Angular 2 or React, should be based on characteristics specific to the given situation.
If we revisit our illustration from earlier, we can see a new stack take form that provides flexibility in choosing front-end frameworks.
A modern stack that offers flexibility in front-end frameworks
Below this upper “view” layer is a common ground that can be built upon by leveraging tools that embrace our key principles. At Kenzan, we feel that this stack converges on a space that captures the needs of both user and developer experience. This yields results that can benefit any team or application, large or small. It is important to remember that the tools presented here are intended for a specific type of project development (front-end UI application), and that this is not intended to be a one-size-fits-all endorsement. Discretion, judgement, and the needs of the team should be the prominent decision-making factors.
We also hope that you’ll recognize the value of the tools we present as being guided by a set of core principles, paradigms, and philosophies. Writing this series has certainly caused us to put our own experience and process under the microscope, and to solidify our rationale when it comes to front-end tooling. Hopefully, you’ll enjoy what we’ve discovered, and we welcome any thoughts, questions, or feedback you may have.
Next up in our blog series, we’ll take a closer look at the first core component of our front-end stack—package management with Yarn.
