How to disable the mock api in the App?

We suggest, please start your project with the starter kit. To fetch data from real APIs, you need to follow the following steps.

  1. Update libs/mockapi/src/index.js/tsx the file's content like below.

import jwtAxios from '@crema/services/axios';

// import MockAdapter from 'axios-mock-adapter';
// export default new MockAdapter(jwtAxios, { delayResponse: 200 });

export default jwtAxios;

  1. Remove the following import statement from the apps/{your app}/src/app.js/tsx file.

import '@crema/mockapi';

  1. Make sure you are using the axios from the following lib in APIHooks or Redux Actions, by default we are using it from '@crema/services/axios'

import jwtAxios from '@crema/services/auth/JWT';

  1. In any case, if you get any reference error related to jwtAxios please fix it by updating the tsconfig.base.json file as follows and restart your project again.

"@crema/services/auth/JWT": ["libs/services/auth/lib/jwt-auth/index.js"],

//replace the above reference with the following

"@crema/services/auth/JWT": ["libs/services/auth/src/jwt-auth/index.js"],
How to fix: BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default (froala-editor\js)
Can't resolve 'crypto' in '..\node_modules\froala-editor\js'
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.

This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "crypto": require.resolve("crypto-browserify") }'
        - install 'crypto-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "crypto": false }

The above error occurs due to the froala-editor compatibility with webpack 5. The froala-editor team will fix this in their next update. Till then you can remove this file libs/modules/src/lib/thirdParty/froalaEditor/index.tsx/js. and remove the froala-editor dependency.

How can I make server-side requests on a page, with the JWT token?

Here is an example of the code getting data from an API using a JWT token on the server side

const Page = (props) => {
  return <PageDetail {...props} />;
};

export const getServerSideProps = async (context) => {
  const { slug } = params;
  const token = getCookie('token', { req, res });
  const props = {};

  try {
    setAuthToken(token);
    const response = await httpClient.get(`get-data/${slug}/`, {
      token: token,
    });
    if (isRequestSuccessful(response.status)) {
      const data= response.data.data;
      props = { data };
    }
  } catch (error) {
    console.log('error: ', error);
  }

  return {
    props,
  };
};

export default Page;
How InfoViewContext works?

InfoViewContext has all the info about the API state like loading/success/error, according to their updated state, it will show the loader, success, and error message on the UI. We can set ferchStart, fetchMessage, and fetchError according to your requirement and This component will handle the state in the proper way

Please let us know if you missed anything in the docs. We will add that asap.
