Axios - Prevent .then() from executing on http errors

My problem:



I have set up an interceptor to catch error codes in HTTP responses.
When the JWT expires, I have a code 401 coming back from the server. Here's my interceptor:



this.axios.interceptors.response.use(undefined, (error) => {
if (error.response.status === 401) {
this.$store.dispatch('auth/logout').then(() => {
this.$router.push({name: 'login'})
return Promise.reject(error)
})
}
})


My interceptor works fine, except the request that is being intercepted still resolves into the .then() part.



this.axios.get('/texts').then(function(){
// This is still being executed and generates javascript errors because the response doesn't contain the right data
})


From the axios documentation, I found out you can prevent this by calling



this.axios.get('/texts').then(function(){
// only on success
}).catch(function(){
// only on errors
}).then(function(){
// always executed
})


But this is pretty verbose and I don't want to do this on every request that my app makes.



My question is:



How do I prevent axios from executing the .then() callback when I have an error. Is it something I can do in the interceptor? Like event.stopPropagation() or something like that?

  • "this is pretty verbose" Maybe... But that's how you do it. If you're looking for a less verbose syntax then consider using async/await (and a transpiler if required).

Did you try catch in the end of the chain? You will get following



this.axios.get('/texts').then(function(){
// only on success
}).then(function(){
// only on success in previous then
}).catch(function(){
// executes on every error from `get` and from two previous `then`
})
