Graphql-code-generator: Strict apolloClientVersion value check breaks fragment-matcher

Created on 8 Feb 2020 · 3Comments · Source: dotansimha/graphql-code-generator

Describe the bug

Specifying apolloClientVersion as integer for fragment-matcher results in error Extension .ts not supported because strict match against string is used at https://github.com/dotansimha/graphql-code-generator/blob/master/packages/plugins/other/fragment-matcher/src/index.ts#L134

In docs it is specified as integer: https://graphql-code-generator.com/docs/plugins/fragment-matcher#apolloclientversion-string-default-value-2

To Reproduce
Steps to reproduce the behavior:

create configuration for example

overwrite: true
schema: './schema/index.ts'
documents: './graphql/**/*.graphql'
generates:
  './graphql/__generated__/introspectionResult.ts':
    hooks:
      afterOneFileWrite:
        - prettier --write
    config:
      apolloClientVersion: 2
    plugins:
      - fragment-matcher

try to generate schema, you will get Extension .ts not supported.
Then change configuration to

overwrite: true
schema: './schema/index.ts'
documents: './graphql/**/*.graphql'
generates:
  './graphql/__generated__/introspectionResult.ts':
    hooks:
      afterOneFileWrite:
        - prettier --write
    config:
      apolloClientVersion: '2'
    plugins:
      - fragment-matcher
