I have had mixed results when using NPM libraries, but I also haven't run into any cases yet where I absolutely needed them
Some stuff you might reach out to NPM for is built into Deno's standard library. Other stuff has become built-in JS language features over the years. And the ecosystem, while nowhere near as big as NPM's, seems to have all the most important stuff at this point, at least for back-end work
And if I have to fill gaps by reinventing some small wheels here and there, or by interning and converting an NPM library, that's still worth it to me to avoid all the tooling headaches
