Hi, great to know that JSPI is moving forward, I tested it on couple of my projects.
*1. Dune 2* compiles: ✅ (yes) regular build: *428Kb* jspi build: *336 Kb -22%* works in chrome: ✅ (yes) performance: *same* (old version also was blazing fast) *2. js-dos dosbox* compiles: ✅ (yes) regular build: *1.4Mb* jspi build: *1.4 Mb * works in chrome: ❌ (no), freezes tab on start *3. js-dos dosbox-x (with exceptions!)* compiles: ✅ (yes) regular build: *6.3Mb* jspi build: *5.9 Mb -7%* works in chrome: ❌ (no), freezes tab on start *2/3 how-to reproduce:* You can find in jspi version of js-dos here: https://v8.js-dos.com/tmp/jspi.zip. 1. Extract it 2. Change origin meta tag in test/dhry2.html and test/test.html 3. Serve contents of dist folder and open test/dhry2.html or test/test.html in chrome *dhry2.html* - is a benchmark, it will print performance estimation if works *test.html* - is a js-dos testsuite, all tests should pass (press "Start Tests" button to start). Both pages stuck at the beginning, regular version works just fine. -- Best regards, Alex сб, 16 мар. 2024 г. в 00:16, 'Brendan Dahl' via emscripten-discuss < emscripten-discuss@googlegroups.com>: > I'm excited to announce that JavaScript Promise Integration (JSPI) is > entering a Chrome origin trial in version 123 > <https://v8.dev/blog/jspi-ot>.
