Apollo Codegen deprecated

[KennyTsui]

It seems like Apollo Codegen has been deprecated and replaced with Apollo, see:
https://www.npmjs.com/package/apollo-codegen
https://www.npmjs.com/package/apollo

> Task :installApolloCodegen
npm WARN deprecated apollo-codegen@0.18.3: The 'apollo-codegen' command has been replaced with the more-powerful 'apollo' CLI. Switch to 'apollo' to ensure future updates and visit https://npm.im/apollo#code-generation for more information.

Based on the output, it looks like Apollo Android still uses the deprecated module, are there plans to migrate to Apollo from Apollo Codegen?

Follow up question: If a provided schema.json exists in the appropriate location, is it possible to skip node and apollo-codegen install entirely?

[sav007]

Yes there is such plan, the only what was blocking us apollographql/rover#537. But seems it fixed now

[anudeep3998]

Any updates on when this will be released?

[sav007]

I'm going to look at it right now

[sav007]

There are still some issues with Apollo code gen module we are trying to resolve. For now there is no big benefit of migrating to new apollo cli

[drsounds]

But it doesn't seems to generate any code anymore

There is, apparently, a problem with the apollo-tooling:0.19.1
https://github.com/apollographql/apollo-tooling/blob/v0.19.1/package.json

it consumes:
"graphql": "^0.13.1",

The problem we get looks similar to
apollographql/apollo-tooling#630 (comment)

and was fixed with (by updating graphql to version 14):
apollographql/apollo-tooling#624

It would be really nice to move to the latest.

Looks like the Apollo CLI doesn't support generating Java code yet. (As of v2.4.4.) Maybe that's the main issue?

Help for apollo client:codegen:

--target=target (required) Type of code generator to use (swift | typescript | flow | scala), inferred from output

There's a PR: [WIP] add support for java and comment syntax

[venik]

Current Gradle plugin implementation generates JSON from GraphQL files and then uses Moshi
https://github.com/square/moshi
to generate Java code, the problem here is that apollo-tooling has a bug, which was solved, but current apollo-android still points to the old (buggy) apollo-tooling

[mirkonasato]

@venik as far as I can tell Moshi is just a JSON parser, not a code generator. It's used by the Gradle plugin only to parse package.json. The plugin uses apollo-codegen to generate Java code.

[venik]

Well, it generates from

query blocksList {
  blocks {
    blockType
  }
}

something java-like

package com.sample.schemaapollo;
...
@Generated("Apollo GraphQL")
public final class BlocksListQuery implements Query<BlocksListQuery.Data, BlocksListQuery.Data, Operation.Variables> {
  public static final String OPERATION_ID = "bc2856a07ab37724cac77379757113c3e0b46fff849dc03bda9697ba58b3ea3e";

  public static final String QUERY_DOCUMENT = "query blocksList {\n"
      + "  blocks {\n"
      + "    __typename\n"
      + "    blockType\n"
      + "  }\n"
      + "}";

  public static final OperationName OPERATION_NAME = new OperationName() {
    @Override
    public String name() {
      return "blocksList";
    }
  };

  private final Operation.Variables variables;

  public BlocksListQuery() {
    this.variables = Operation.EMPTY_VARIABLES;
  }
  ...

@sav007 Any news on this? Just integrated Apollo into my project and also noticed a build warning that seems to be related to this?

deprecated apollo-codegen@0.19.1: The 'apollo-codegen' command ahs been replaced with the more-powerful 'apollo' CLI

[ashish-patidar-rau]

i have a same problem

npm WARN deprecated apollo-codegen@0.19.1: The 'apollo-codegen' command has been replaced with the more-powerful 'apollo' CLI. Switch to 'apollo' to ensure future updates and visit https://npm.im/apollo#code-generation for more information.

Is any other way to implement Apollo into Android?

[ghadly]

Getting the same warning from the CI tool, any news ?

npm WARN deprecated apollo-codegen@0.19.1: The 'apollo-codegen' command has been replaced with the more-powerful 'apollo' CLI. Switch to 'apollo' to ensure future updates and visit https://npm.im/apollo#code-generation for more information.

apollo-codegen is going away soon: #1482.

You can actually already test this in the 1.0.3-SNAPSHOT version.

[sav007]

Please try latest version with a new code generation engine https://github.com/apollographql/apollo-android/releases/tag/1.1.0

If you see the same issue pls reopen.
