You may also make use of this API in the event your explore case pertains to getting in touch with esbuild’s build API several times with the exact same alternatives. Progressive stimulates be productive than simply regular builds given that some of the details try cached and will feel reused if the original data have not changed given that history build. You can find already a few forms of caching utilized by brand new progressive create API:

Data try kept in recollections and therefore are maybe not lso are-understand about document program in the event your document metadata has not yet altered while the last generate. This optimization merely applies to document system routes. It does not affect virtual segments produced by plugins.

Parsed ASTs is kept in memory and you can re-parsing the brand new AST try eliminated whether your file content haven’t altered while the past create. That it optimization pertains to virtual modules produced by plugins at the same time so you’re able to document system modules, so long as the latest virtual component highway continues to be the same.

This option says to esbuild how to handle JSX syntax. You can either have esbuild transform JSX so you’re able to JS (new standard) otherwise keep the fresh new JSX syntax about production. In preserving JSX sentence structure:

Remember that if you uphold JSX sentence structure, new productivity data are no longer good JavaScript password. This particular aspect will probably be utilized when you need to alter the fresh new JSX syntax inside the esbuild’s yields files from the some other device immediately after bundling, always one to having a separate JSX-to-JS transform as compared to you to esbuild implements.

#JSX warehouse

You can label one thing except that React.createElement from the changing the JSX factory. Such as for instance, to-name the event h alternatively (which is used by the most other libraries like Preact):

As an alternative, when you use TypeScript, you can just configure JSX having TypeScript with the addition of that it to help you their tsconfig.json document and you will esbuild is pick it up automatically without the need for is configured:

#JSX fragment

You should use a component except that React.Fragment by the switching the latest JSX fragment. Including, to utilize the fresh part Fragment instead (which is used of the almost every other libraries like Preact):

Instead, by using TypeScript, you can simply configure JSX having TypeScript adding it to help you your own tsconfig.json document and esbuild should figure it out instantly without the need for as designed:

#Keep brands

Inside JavaScript the name possessions on properties and you can categories non-payments so you can a nearby identifier from the source code. These types of sentence structure versions all set the name property of the setting to „fn“ :

Although not, minification renames symbols to reduce code proportions and you will bundling both you prefer so you can rename signs to cease crashes. One to change value of the name property for most of those circumstances. It’s usually okay as the label house is generally merely employed for debugging. Although not, some structures rely on title assets to have registration and you will binding aim. Should this be the way it is, you could enable this option in preserving the initial name thinking despite minified password:

#Judge statements

Good „legal feedback“ is recognized as being one statement-level review when you look at the JS or signal-height opinion when you look at the CSS who has or otherwise one to begins with //! otherwise /*! . These types of statements try maintained when you look at the output records automatically as the you to comes after the brand new intent of your own new writers of your password. not, that it decisions is designed that with among the many following options:

The new standard decisions are eof whenever bundle is actually allowed and you may inline or even. Setting the judge review function works out so it:

Keep in mind that „statement-level“ having JS and you will „rule-level“ to have CSS means the remark need to come in a framework in which several comments otherwise legislation are allowed like from the greatest-top scope or perhaps in a statement otherwise laws cut off. Very comments into the terms or on report datingmentor.org/nicaraguan-chat-rooms height commonly sensed permit statements.
