axios-case-converter-updated

Axios transformer/interceptor that converts snake_case/camelCase

Converts outgoing data params object keys into snake_case
Converts incoming data object keys into camelCase
Converts outgoing headers object keys into Header-Case
Converts incoming headers object keys into camelCase

Usage

You can fully use camelCase.

import applyConverters from 'axios-case-converter-updated';
import axios from 'axios';

(async () => {
  const client = applyConverters(axios.create());
  const { data } = await client.post(
    'https://example.com/api/endpoint',
    {
      targetId: 1
    },
    {
      params: { userId: 1 },
      headers: { userAgent: 'Mozilla' }
    }
  );

  console.log(data.actionResult.users[0].screenName);
})();

Attention

`FormData` compatibility

If you use FormData on Internet Explorer or Safari, you need polyfill of FormData.prototype.entries().

jimmywarting/FormData: HTML5 FormData polyfill for Browsers.

If you use FormData on React Native, please ignore the following warnings after confirming that polyfill is impossible.

// RN >= 0.52
import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings([
  'Be careful that FormData cannot be transformed on React Native.'
]);

// RN < 0.52
console.ignoredYellowBox = [
  'Be careful that FormData cannot be transformed on React Native.'
];

`Symbol` compatibility

If you use React Native for Android development, you should use Symbol polyfill from core-js to avoid bugs with iterators:

Create polyfill.js in root directory with code:

global.Symbol = require('core-js/es6/symbol');
require('core-js/fn/symbol/iterator');

Include polyfill.js in entry point of your app (e.g. app.js):

import { Platform } from 'react-native';

// ...

if (Platform.OS === 'android') {
  require('./polyfill.js');
}

cf. undefined is not a function(evaluating '_iterator[typeof Symbol === "function"?Symbol.iterator:"@@iterator"]()') · Issue #15902 · facebook/react-native

Usage no npm install needed!
