How to pass parameters or arguments to the axios interceptor with JavaScript?

Estimated read time 1 min read

Axios interceptors are functions that are called for every request or response made with Axios. To pass parameters or arguments to an Axios interceptor, you can define the interceptor as a closure that takes the parameters you want to pass in as arguments.

Here’s an example of how you could pass a parameter token to an Axios request interceptor:

function createInterceptor(token) {
  return function (config) {
    config.headers.Authorization = `Bearer ${token}`;
    return config;

const interceptor = createInterceptor('your-token-here');


In this example, we define a closure createInterceptor which takes the token parameter. The closure returns another function which will be used as the Axios request interceptor. The inner function takes the config object as an argument and adds an Authorization header to the request with the value Bearer followed by the token argument passed to createInterceptor. Finally, we create an instance of the interceptor by calling createInterceptor with the desired token value, and add it to the Axios request interceptors using axios.interceptors.request.use(interceptor).
