That one kits brand new production index on build process. Particularly, that it demand can establish a collection titled aside :
This new production directory might possibly be generated in the event it does not already occur, but it are not eliminated when it already contains some records. One generated documents will silently overwrite current records with the same label. You will want to clear the newest returns list your self prior to running esbuild if the you want new productivity directory to only contain data in the most recent run from esbuild.
Should your build includes multiple entryway things when you look at the separate directories, the new index structure will be replicated towards returns index creating regarding the reasonable preferred predecessor directory certainly one of all the input access point pathways. Like, when the there are 2 entry items src/ home/ directory.ts and you can src/ about/ list.ts , the newest productivity index have a tendency to incorporate home/ directory.js and you can about/ directory.js . When you need to personalize so it choices, you need to alter the outbase directory.
This option kits the fresh new productivity document name on generate procedure. This is just appropriate if there’s just one access point. If the there are several admission facts, you must make use of the outdir option instead so you’re able to identify an efficiency directory. Playing with outfile looks like that it:
Automagically, esbuild’s bundler is actually designed to create code intended for the latest browser. When your bundled code is intended to run in node alternatively, you really need to set the working platform to node :
If the a package determine a chart into web browser industry inside its plan.json file, esbuild uses that map to change specific data files or modules with regards to browser-amicable products. Instance, a great deal you are going to have a substitution off path having roadway-browserify .
An element of the areas means is determined to help you internet browser, component, head however with particular even more unique behavior. When the a deal aids module and you can head not web browser up coming head can be used instead of module if that package was actually brought in using need() . Which behavior improves compatibility that have CommonJS segments one export a features from the assigning they in order to component.exports .
New criteria function immediately includes the latest internet browser standing. So it change how exports community into the bundle.json data files try translated so you can favor internet browser-particular password.
While using the build API, all procedure. env. NODE_ENV words was automatically laid out in order to “production” in the event that all the minification options are permitted and you can “development” if you don’t. It simply goes in the event the procedure , process.env , and procedure.env.NODE_ENV are not already defined. This replacement is necessary to avoid Perform-oriented password crashing immediately (because procedure is an excellent node API, not a web site API).
Whenever bundling try permitted the new default output format is set in order to cjs , and this means CommonJS (the latest component format used by node). ES6-concept exports having Yonkers escort service fun with export comments would-be changed into getters towards the brand new CommonJS exports object.
