You can use this API when your play with circumstances involves getting in touch with esbuild’s build API a couple of times with similar possibilities. Progressive creates are more productive than simply typical generates as a few of the information is actually cached and will end up being used again in case your brand-new files have not altered just like the history generate. There are currently a couple kinds of caching used by new incremental build API:
Data files are stored in memories consequently they are not re also-see regarding the file program in case the document metadata has not yet changed as the past make. Which optimization merely relates to file program pathways. It doesn’t affect digital modules created by plugins.
Parsed ASTs try stored in thoughts and you may re-parsing the latest AST are avoided in case the file content material haven’t changed as the history create.
