fsPromises.access() Method

fsPromises.access() Method is a Node.js idea you prove with fetch a user then marks, not with a slogan.

For fsPromises.access() Method, the event loop is in play. Don’t blame it until you have traced fetch a user then marks.

Skip fsPromises.access() Method and unhandled rejection shows up in an API handler.

Farhan ships fsPromises.access() Method in an API handler. That is the use case worth saying.

fsPromises.access() Method trap — unhandled rejection. Farhan loses marks for that every viva.

After fsPromises.access() Method, Farhan should still remember unhandled rejection.

Close fsPromises.access() Method with: “If I skip it, fetch a user then marks goes wrong like this: unhandled rejection.”

Exam tip

Board: fetch a user then marks. Dry-run fsPromises.access() Method. Name the trap: unhandled rejection.

Example

// fsPromises.access() Method
const users = [
  { id: 1, name: "Asha" },
  { id: 2, name: "Ravi" },
];

function findUser(id) {
  return users.find((u) => u.id === id) ?? null;
}

console.log(findUser(2));
console.log(users.map((u) => u.name));

fsPromises.access() Method: find user 2, then list names. Say both prints.
