Error Handling and Global Interceptors

Handle request errors and configure Axios interceptors.

Requests Can Fail

Networks drop, servers return errors, and tokens expire. Robust apps anticipate failure and respond gracefully instead of crashing or leaving the user staring at a spinner forever.

try/catch Around Requests

Wrap awaited requests in try/catch to capture errors. Axios throws when the server responds with a 4xx or 5xx status.

async fetchPosts() {
  try {
    const res = await api.get("/posts")
    this.posts = res.data
  } catch (err) {
    console.error(err)
  }
}
