javascript - de ce browserele nu îmi citesc modulele importate, dar node.js le citește?
Deci sunt nou în Typescript, Javascript și ecosistemul NPM. Creez o dapp pentru un client și m-am blocat cu o problemă care apare doar când încerc să folosesc unele pachete npm în browser, dar nu când le rulez pe node.js.
iata structura mea de foldere (am mutat totul în directorul rădăcină pentru simplitate): fișiere
Iată modulele pe care încerc să le import: pachete npm
și aici este eroarea în consola browser-ului (nu primesc o eroare de rulare când folosesc modulele cu node): eroare în consolă
iată codul necesar pentru a reproduce problema:
