you will have tested your application on a specific version.There are number of advantages to controlling the version: As you can see from the src URL below I included version 5.5.3:
#UNPKG THREE CODE#
So if my code had been defaulting to the latest version then my application would have failed.įortunately I had imported a specific version of faker from unpkg. In my open source table editing tool I use three libraries: AG Grid, PapaParse, and Faker.įaker recently had an issue where a recent version deployed to npm had issues. How (and Why) to Control the Version of the Library īoth of these CSS files are also deployed to and can be included into our project from a CDN. The Theme Style sheet provides the visual aesthetics for the Grid. The Structural Style sheet provides the CSS that will layout the data as a Grid. These would be referenced from the CDN as normal using link elements.įor example, AG Grid uses two style sheets. For example, AG Grid deploys CSS files as well as JavaScript.
#UNPKG THREE PROFESSIONAL#
These are all professional and well-run sites. In the source code for my earlier freeCodeCamp post, I used the CDN to import AG Grid in my code using a script element.Īs with all code that we copy and paste, it's worth understanding what it does so that we can handle any issues. Npm-driven CDNs monitor the releases distributed via npm, and host the releases on their own site. Instead, programmers can add a direct reference to AG Grid from a CDN like.
#UNPKG THREE HOW TO#
We can use an 'npm driven CDN' as the host for libraries, without having to use npm.Īn 'npm-driven CDN' is one which hosts the distribution code for libraries which deploy to npm.įor example, AG Grid which I demonstrated in my article " How to Convert a Static HTML Table to a Dynamic JavaScript Data Grid" deploys to npm but does not have its own CDN. We don't have to be using npm and JavaScript build processes to take advantage of the npm eco-system. npm downloads the library from a CDN and adds it to the project locally. Most libraries deploy to and rely on the programmer adding the library to their project via npm at build time. If most JQuery applications import the JQuery library from this CDN, then users are more likely to have JQuery in their cache already.
#UNPKG THREE DOWNLOAD#
This speeds up your site because the browser doesn't need to download the library again.įor example, JQuery has an official JQuery CDN. This can make your application faster than hosting files yourself.ĬDN's also have the advantage that if you are using libraries common to multiple sites then your users may already have the file cached in their browser. They are usually highly performant and offer location cached files so no matter where your users are, they receive the files from geo locations close to them. These are file hosting services for multiple versions of common libraries. What is a CDN?Ī CDN is a Content Delivery Network. In fact, if you've followed any JavaScript tutorial for a library, then you've probably already used a public CDN but may not be aware of it. This can simplify deploying the application and keeping dependencies up to date. Most popular JavaScript libraries are available from a public Content Delivery Network (CDN). When you're writing a Vanilla JavaScript application, you don't have to host all the code you use on your own site.
