Particularly, this can be helpful whenever you are implementing a file watcher service
You may also make use of this API if the fool around with circumstances relates to contacting esbuild’s generate API many times with similar alternatives. Progressive stimulates be much more productive than typical produces due to the fact some of the knowledge is cached and certainly will feel used again whether your new records have not changed due to the fact history build. You will find already several types of caching utilized by the fresh new incremental generate API:
Records are stored in recollections and are also maybe not lso are-read regarding the file program if the document metadata have not changed since past build. This optimization just relates to file program pathways. It will not connect with virtual modules produced by plugins.
Parsed ASTs is kept in recollections and you may lso are-parsing the newest AST was averted should your file articles haven’t changed once the past generate. This optimization pertains to virtual segments produced by plugins on top of that in order to file program segments, for as long as new digital module path remains the exact same.
That one says to esbuild how to handle JSX sentence structure. You can either keeps esbuild transform JSX so you’re able to JS (the latest standard) or preserve the fresh new JSX sentence structure about returns. In preserving JSX sentence structure:
Note that for folks who maintain JSX sentence structure, the brand new yields files are not any longer good JavaScript code. This particular aspect is intended to be used when you wish so you’re able to transform the newest JSX syntax during the esbuild’s production documents of the several other equipment immediately following bundling, usually one with another type of JSX-to-JS change as compared to one esbuild executes.
#JSX warehouse
You could name anything aside from Act.createElement because of the altering the newest JSX factory. Such as, to-name case h instead (that is used from the other libraries instance Preact):
As an alternative, if you utilize TypeScript, you can just arrange JSX to have TypeScript by adding it so you can your own tsconfig.json file and you can esbuild would be to figure it out immediately without the need for becoming set up:
#JSX fragment
You should use a component except that Respond.Fragment of the changing the newest JSX fragment. For example, to use brand new component Fragment alternatively (that is used because of the most other libraries such as for example Preact):
Alternatively, by using TypeScript, you can simply configure JSX to own TypeScript by adding it to help you your own tsconfig.json document and esbuild is to pick it up immediately without needing to get configured:
#Continue names
When you look at the JavaScript title assets to the services and you will groups defaults to your local identifier on source password. Such sentence structure versions ready to go title assets of your mode so you can “fn” :
Although not, minification renames symbols to minimize password size and you can bundling either you prefer to help you rename symbols to get rid of collisions. You to change worth of title possessions for almost all of these instances. This is usually great just like the identity property is generally only utilized for debugging. But not, certain buildings believe in title possessions to possess registration and binding aim. If this is happening, you can permit this to preserve the first title beliefs despite minified password:
#Legal statements
An effective “court comment” is recognized as being one declaration-top feedback inside JS or rule-top comment into the CSS with or otherwise one to begins with //! otherwise /*! . These statements is preserved for the output data files automagically because the one follows new intent of your completely new article writers of your own code. Yet not, it choices shall be set up by using among the many pursuing the options:
The fresh default choices are eof when package is actually allowed and you may inline otherwise. Mode the fresh legal feedback means ends up this:
Remember that “statement-level” for JS and “rule-level” to possess CSS mode the fresh review must are available in a perspective in which several statements otherwise regulations are allowed such as for example on the greatest-top range or perhaps in an announcement or laws stop. Thus comments to the expressions otherwise during the declaration top are not experienced licenses statements.
