I’m trying to test out `@defer`/`incremental delivery feature`. The documentation said it requries `graphql@17`. So, I added `"graphql": "^17"` to my `dependencies`. But `npm install` gives me this error. ```auto npm ERR! Found: graphql@undefined npm ERR! node_modules/graphql npm ERR! graphql@"^17" from the root project npm ERR! npm ERR! Could not resolve dependency: npm ERR! peer graphql@"^16.6.0" from @apollo/server@4.3.2 npm ERR! node_modules/@apollo/server npm ERR! @apollo/server@"^4.3.2" from the root project ``` ---

Hey there @Dulguun_Otgon, [@defer is supported on Apollo Router](https://www.apollographql.com/docs/router/executing-operations/defer-support/), starting with version 1.8. This unfortunately doesn’t include Apollo Server. **Edit: I was mistaken! Please see Trevor’s answer below.** ---

Does `@apollo/gateway` support this feature as well? ---

@Dulguun_Otgon - in order to use defer and graphql v17 with Apollo Server you have to “force” install it using the npm `--legacy-peer-deps` flag like so: ```auto npm i --legacy-peer-deps graphql@alpha ``` ---

Is it about the server or gateway? I’ve tried what you suggested but I get the unknown directive error. I think `--legacy-peer-deps` option still lets other packages use what they specified in their `peerDependencies`. Another question. Will Apollo gateway and server support @defer in the future without force installing dependencies? ---

Even this doesn’t work for me ```json { "name": "experiments", "private": true, "workspaces": [ "packages/*" ], "dependencies": { "@apollo/gateway": "^2.3.0", "@apollo/server": "^4.3.2", "@apollo/subgraph": "^2.3.0", "graphql": "^17.0.0-alpha.2", // other dependencies }, "overrides" : { "graphql" : "$graphql" } } ``` ---

Apollo Gateway will never support defer, but Router does (with some caveats). Apollo Server on its own (no federation) does support defer, and will eventually support it without any workarounds once graphql v17 is generally available. ---

Thank you. I’ve decided to migrate to router. What are the caveats you mentioned? Detailed info on that would be really useful to me in the future. ---

I would recommend reading the [docs page](https://www.apollographql.com/docs/router/executing-operations/defer-support/) for that so you’ve got the full picture.
