Recently,Parcel2releasebeta3Version.
The biggest update of this version is to replace theJSCompiler, fromBabelReplace withSWC, which makes the overall compilation speed 10x times faster than before.
SWCYesRustWrittenJSCompiler, the goal is to replaceBabel。 His author was born in 1997강동윤, he wroteswcI am a sophomore.
Parcel tired by speed
In order to work with packing tools, big brotherWebpackDifferentiated competition,ParceltakeZero configurationAs his selling point (benchmarkingWebpackCumbersome configuration)
Among them, advancedESThe syntax will be based on thebrowserslistTarget version degraded to correspondingES5Syntax.
Nonstandard syntax, similarJSX、TS, development environment features, similarReact Fast RefreshThey are all out of the box.
The realization of all this is based onBabelofJS compilerUp.
andJScompareRustThe speed disadvantage at the language level isBabelNo amount of optimization can make up for it.
Thus, there is the replacement mentioned at the beginningJScompiler.
ParcelThe team said,SWCthanBabel20x faster
It is worth pondering that in providingbenchmarkWhen showing performance,ParcelUsedesbuildofbenchmark。

Volume of speed
esbuildIs aGoWrittenJSPackaging tool, open source in january2020. His author isFigmaofCTO Evan Wallace。
Once open source, there are no fancy new functions, and the hard and hard compilation speed comes up.
Outstanding achievements:
Can seeParecel2Third from bottom.
And big brotherWebpack5The reason why there is no reciprocal first is that the reciprocal first isWebpack4。
EvanLater updatedbenchmark：
althoughParcelIts advantages are: minimalism and zero configuration. But being pulled out like this is faster than the speed, the result is still so tragic.
PresumablyParcelTeam members are extremely oppressed.
So, brothers, let’s put aside other things first. Let’s roll up the compilation speed together!
After several months of development, we finally have thebeta3。 And I have to use youesbuildofbenchmarkRun again and find the court!
Dimension reduction attack of JS packaging tool
In fact, inWebpackToday, which has been developed for many years, can highlightWebpackEncirclement and packaging tools that occupy a place are all following the line of differentiated competition.
stayGoogleengineerSurmaPackaging tool evaluation website developed with otherstooling.reportYou can see:
WebpackIt supports the most comprehensive functions. Other mainstream packaging tools have their own emphasis.
The direction of the script should have been:
WebpackKeep going heHexagon WarriorRoute of
Other packaging tools are well installed and follow the differentiated route.
However,esbuildThe sudden rise of has caused a dimension reduction blow to these tools.
Compilation speedIt is really just needed at the time of development.
ParcelIt is not the first and by no means the last tool for change.
Smart vite
Some people embrace change, others are forced to accept it.
