I’m not a heavy JS/TS dev so here’s an honest question: why not use Bun and forget about node? Sure I understand that not every project is evergreen but isn’t Bun a much runtime in general? It supports TS execution from day 1, has much faster dependency resolution, better ergonomics… and I could keep going.
I know I’m just a single data point but I’ve had a lot of success migrating old node projects to bun (in fact I haven’t used node itself since Bun was made public)
Again, I might be saying something terribly stupid because JS/TS isn’t really my turf so please let me know if I’m missing something.
Node is much more stable than bun. bun has numerous crash bugs, something that is unheard of with Node.
I'd say that it's entirely the other way around: they stuck to the practical convenience of solving the problem that they had in front of them, quickly, instead of analyzing the problem from the first principles, and solving the problem correctly (or using a solution that was Not Invented Here).
Go's filesystem API is the perfect example. You need to open files? Great, we'll create
function, you can open files now, done. What if the file name is not valid UTF-8, though? Who cares, hasn't happen to me in the first 5 years I used Go.They could support passing filename as `string | []byte`. But wait, go does not even have union types.
