I admire Evan W., the creator of esbuild, and I believe we'll eventually get the JS/TS instant builds one day. Same as in Deno-land. I wish I could help somehow. I hope I messed up my configs, and it's me not esbuild.
In this context...
Programs built by esbuild v0.11.5 appear to perform on average 27% slower than the same code built by Rollup. Some packages perform more than 90% slower though!
Here are the details of the benchmarks. I hope it's me, not esbuild.
Read article esbuild is faster but the built programs on average are slower
