axios response.json

What is axios response.json?

axios is a popular JavaScript library used to make HTTP requests from a web browser or node.js. The response.json method is used to extract the JSON data from the response object when making a request with axios.

How to use axios response.json

When making a request with axios, the response is returned as a promise. To extract the JSON data from the response, we use the response.json method.

Here's an example:

axios.get('/api/data')
  .then(response => {
    // extract JSON data from response
    return response.json();
  })
  .then(data => {
    // use JSON data
    console.log(data);
  })
  .catch(error => {
    console.error(error);
  });

In this example, we are making a GET request to the '/api/data' endpoint. The response is returned as a promise, which we then extract the JSON data from using the response.json method. We then use the JSON data in the next promise chain.

Alternative ways to use axios response.json

There are other ways to extract JSON data from a response object in axios. One way is to use the axios.defaults.transformResponse configuration option.

Here's an example:

axios.defaults.transformResponse = [(data) => {
  // parse JSON data
  return JSON.parse(data);
}];

axios.get('/api/data')
  .then(response => {
    // data is already parsed as JSON
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

In this example, we are setting the axios.defaults.transformResponse configuration option to a function that parses the JSON data. This means that all responses will automatically be parsed as JSON.

We then make a GET request to the '/api/data' endpoint and access the parsed JSON data using the response.data property.

Conclusion

axios response.json is a method used to extract JSON data from the response object when making a request with axios. There are multiple ways to use this method, including using the response.json method or setting the axios.defaults.transformResponse configuration option.
