Strange anomalies arising in frontend Apollo and GraphQL integration

Currently, I am working with nuxt.js and apollo. One issue I am facing is that when I click a button, it sends a request to the graphql server. The strange part is that the first time I click the button, everything works as expected. However, when I click it a second time, it returns the same data without contacting the server again. This leads me to believe that Apollo may be mistakenly caching the data. I am unsure of how to resolve this issue. Does anyone have any suggestions on how to fix this?

Answer №1

If you want to turn off caching, there are two ways to do it - either globally or for a specific query.

For global disabling:

const client = new ApolloClient({
  cache,
  link,
  defaultOptions: {
    fetchPolicy: 'no-cache'
  }
})

To disable caching for a specific query:

apollo: {
  foo: {
    query: ...,
    fetchPolicy: 'no-cache'
  }
}

Answer №2

Another possibility could be that the Apollo server configuration is causing it to return duplicate data. Make sure to verify if caching is activated on the server side.

cacheControl: { defaultMaxAge: 5 },

To resolve this issue, either set defaultMaxAge to 0 or remove cacheControl entirely.
