![]() Snowpack works on any ESM package, even ones with ESM & Common.js internal dependencies. Snowpack checks your package.json manifest for any "dependencies" that export a valid ESM "module" entry point, and then installs them to a local web_modules/ directory. ✔ Snowpack installed web-native dependencies. ![]() Snowpack is a dependency install-time tool that lets you dramatically reduce the need for other tooling and even skip Webpack or Parcel entirely. It's not a build tool and it's not a bundler (in the traditional sense, anyway). Snowpack installs modern npm dependencies in a way that lets them run natively in the browser, even if they have dependencies themselves. This can be due to either legacy dependencies of the package itself or the special way in which npm packages import dependencies by name. Unfortunately, most will still fail to run. □ It's easy enough to write web-native ESM code yourself, and it is true that some npm packages without dependencies can run directly on the web. What's stopping us from running them directly on the web? We have these great, modern ESM dependencies now (almost 50,000 on npm!). Like Richard Hubbell, we are all so steeped in this world of bundlers that it's easy to miss how things could be different. ![]() Hopefully, you use something like Create React App (CRA) to get started quickly, but even this will install a complex, 200.9MB node_modules/ directory of 1,300+ different dependencies just to run "Hello World!" Today, it's nearly impossible to build for the web without using a bundler like Webpack. In 2019, you should use a bundler because you want to, not because you need to.Ĭreate React App visualized: 1,300 dependencies to run "Hello World" Complexity Stockholm Syndrome # Snowpack is an attempt to free web development from the bundler requirement. Whether you love this or hate it, it's hard to deny that bundlers have added a ton of new complexity to web development - a field of development that has always taken pride in its view-source, easy-to-get-started ethos. Over the last several years, JavaScript bundling has morphed from a production-only optimization into a required build step for most web applications. Yet we continue to use bundlers for every single thing that we build. We have this new JavaScript module system (ESM) that runs natively on the web. "Most of the newscasts featured Hubbell reading a script with only occasional cutaways to a map or still photograph." It would be a while before anyone would show actual video clips on the TV news.Īs a JavaScript developer in 2019, I can relate. In a world that has only known radio, you stick to what you know. You are about to give one of the world's first major TV news broadcasts, and you have 15 minutes to fill. You work at an experimental New York television studio owned by CBS. This article has been updated all references from to Snowpack. Update (03-29-2020): This article was originally written about a year ago about a new project called Early this year that project was superseded by Snowpack, a web application builder for less tooling and 10x faster iteration. A Future Without Webpack Snowpack installs npm packages that run natively in the browser.
