Replace terser with esbuild or swc minifier

[guoyunhe]

🙋 feature request

Minification can take 30~50% of total production building time. However, terser isn't very good in performance. In our project, replacing terser with esbuild, reduced our build time by 34%. swc's minification is also very fast.

🤔 Expected Behavior

Use fast esbuild or swc as minifier.

😯 Current Behavior

Use slow terser as minifier.

💁 Possible Solution

You can swap out the terser optimizer yourself with @parcel/optimizer-swc or @parcel/optimizer-esbuild. But we've found that, for now, they are either producing bigger or invalid output: #7212 (comment)

.parcelrc:

{
	"extends": "@parcel/config-default",
	"optimizers": { "*.js": ["@parcel/optimizer-swc"] }
}

What is the current state of swc and esbuild optimizer?

The next Parcel release is going to use swc by default: #8860
