Dark Art of Webpack Bundle Tuning
While webpack continues to become more and more popular and de-facto choice of module bundling in an increasingly ES6 and ES7 centric world, its VERY easy to get lost in all the hoopla of getting the webpack to work.
What the developers endup with is - huge bundles for your application - which are slow to load up and degrade user experience.
The talk will showcases such scenario, introduce tools and fixes to alleviate the issues.
At the end of the session, users will know how to utilize Webpack more optimally.
A typical flow of talk would be to showcase following:
a. A typical application having bloated webpack bundles
b. Tools to analyze the bundles and how to read / understand the output of those tools. (2-4 tools)
c. Based on hints / information from the tools, perform “live-fixes” / “walk through git-diff” to show how small changes in chunk definitions / import statements, etc can make big changes in your webpack bundle sizes.
d. How extract-text-plugin can help get CSS moved out of bundles for production and get more performance benefit.
e. how to turnon / turn-off source maps for PROD build.
The audience is expected to know what webpack is and its basic usage.
