You’ll be able to utilize this API in the event the use circumstances concerns contacting esbuild’s build API repeatedly with the exact same solutions. Progressive builds be efficient than just regular builds given that some of the info try cached and can end up being used again in the event your brand-new files haven’t altered once the history make. You will find currently a couple forms of caching employed by new progressive make API:

Data is actually stored in memory and are also perhaps not re also-realize about file program if for example the document metadata have not altered since the last make. So it optimisation just relates to document program routes. It doesn’t connect with virtual segments developed by plugins.

Parsed ASTs are stored in memory and you may re also-parsing the fresh AST was averted in case your document content have not changed since the history build. Which optimization relates to digital modules developed by plugins as well to help you file program modules, so long as the digital component highway remains the same.

This package says to esbuild how to handle JSX sentence structure. You may either enjoys esbuild alter JSX so you’re able to JS (the new default) or keep the fresh JSX syntax about productivity. In preserving JSX syntax:

Observe that for those who keep JSX sentence structure, new output data are not any offered legitimate JavaScript code. This feature is intended to be utilized when you wish so you’re able to changes the brand new JSX syntax in esbuild’s productivity data from the another tool immediately following bundling, always that that have a separate JSX-to-JS transform as compared to you to definitely esbuild implements.

#JSX facility

You can call some thing other than Function.createElement by modifying this new JSX factory. For example, to-name the big event h as an alternative (which is used from the almost every other libraries such as for instance Preact):

Instead, if you use TypeScript, you can just arrange JSX to own TypeScript by adding which so you’re able to your tsconfig.json file and you will esbuild is to figure it out immediately without the need for to-be set up:

#JSX fragment

You can use a feature apart from Act.Fragment from the modifying the brand new JSX fragment. Such as for instance, to make use of brand new role Fragment alternatively (that is used by the almost every other libraries such as Preact):

As an alternative, by using TypeScript, you can simply configure JSX to own TypeScript by the addition of this in order to your tsconfig.json file and you will esbuild will be figure it out automatically without the need for to-be designed:

#Keep labels

For the JavaScript the name possessions with the functions and you may categories non-payments so you can a nearby identifier regarding the resource password. These types of sentence structure versions prepared title property of one’s mode so you’re able to “fn” :

However, minification renames signs to minimize password dimensions and you can bundling both you need in order to rename signs to avoid collisions. You to changes value of the name assets for the majority of of these circumstances. Normally great given that label house is generally speaking simply used for debugging. However, particular frameworks rely on title property to own registration and you will joining intentions. If this is the fact, you could potentially permit this to preserve the original label values even yet in minified code:

#Courtroom statements

A good “court remark” is recognized as being one report-peak review in JS or laws-height comment into the CSS containing otherwise or you to definitely begins with //! or /*! . These types of statements try kept for the efficiency files automagically since you to definitely follows brand new intent of your own brand spanking new experts of one’s code. Yet not, which choices might be designed by using among following the options:

The fresh standard behavior was eof whenever bundle are enabled and you will inline if you don’t. Match vs Zoosk cost Form the newest courtroom feedback form works out it:

Observe that “statement-level” for JS and “rule-level” for CSS function the brand new review need to can be found in a perspective where numerous statements otherwise regulations are allowed like about greatest-level range or perhaps in an announcement or code stop. Very statements into the phrases otherwise on report height are not noticed license comments.
