# -graphql-codegen-typescript-graphql-request-with-retries

forked from @graphql-codegen/typescript-graphql-request with additional retry handling for requests

# example of using the generated SDK with a retry policy from [`polly-js`](https://github.com/mauricedb/polly-js).

```typescript

import { GraphQLClient } from 'graphql-request';

import { getSdk } from './generated/types';

import { ASTNode, print } from 'graphql';

import { Variables } from 'graphql-request/dist/src/types';

import { RetryWrapper } from 'typescript-graphql-request-with-retries';

import polly from 'polly-js';

const client = new GraphQLClient(process.env.GRAPHQL_URL, {

  headers: {

    'x-hasura-admin-secret': process.env.HASURA_GRAPHQL_ADMIN_SECRET,

  },

});

export const request = (query: ASTNode, variables?: Variables) =>

  client.request(print(query), variables);

const withRetries: RetryWrapper = (action: () => Promise) =>

  polly()

    .handle((err: Error) => {

      console.log('HANDLE', err.message);

      return err.message.includes('connect ETIMEDOUT');

    })

    .waitAndRetry(3)

    .executeForPromise(info => {

      console.log('RETRY', info);

      return action();

    });

const sdk = getSdk(client, withRetries);

export default sdk;

```

# Unit test

```typescript

import nock from 'nock';

import graphqlClient from 'shared/graphqlClient';

describe('graphqlClient', () => {

  beforeAll(() => nock.disableNetConnect());

  afterAll(() => nock.enableNetConnect());

  afterEach(() => nock.cleanAll());

  it('retries twice when ETIMEDOUT', async () => {

    nock(/localhost|botany-db/)

      .post('/v1/graphql')

      .replyWithError({ code: 'ETIMEDOUT', message: 'connect ETIMEDOUT' });

    nock(/localhost|botany-db/)

      .post('/v1/graphql')

      .replyWithError({ code: 'ETIMEDOUT', message: 'connect ETIMEDOUT' });

    nock(/localhost|botany-db/)

      .post('/v1/graphql')

      .replyWithError({ code: 'ETIMEDOUT', message: 'connect ETIMEDOUT' });

    try {

      await graphqlClient.GetDataSource({

        dataSourceId: 'github',

      });

    } catch (e) {

      console.log('LAST ERROR', e, e.stack);

    }

  });

});
