flogy / graphql-retain-transformer Goto Github PK

👋 This is Rene from the AWS Amplify team! First off, THANK YOU for your amazing plugin!

I have some great news to share, we've rewritten the GraphQL Transformer plugin from the ground up to take advantage of some really amazing capabilities. All the details here: aws-amplify/amplify-cli#6217 (comment)

How to migrate your plugin to GraphQL Transformer v2

In order to make this plugin forward compatible with GraphQL Transformer v2, you need to make some tiny adjustments to the classes you inherit from. Migration steps here: https://gist.github.com/renebrandel/0b9537e2016e3dd9ed6d794b30b2e3f4

Happy to also hop on a call with you to walk you through the process. Email me at any time: renbran at amazon dot com

hi

I've been searching through Github for as many graphql transformers for AppSync (an AWS Amplify) as I can find and came across this. Is there any chance you can expand on the readme to give more context about what this actualy does, why might I want to use it, what the implications are etc.

It sounds like a think I might find useful but there is just not quite enough info to know for sure :)

Cheers

Pete

Hi there,

Thanks a lot for this. This really should be part of Amplify core, but until then, this plugin has worked very well for us for about a month.

The biggest issue for us was figuring out how we install this package in the build process without installing our entire package.json which includes all our frontend packages.

We did a --no-save in the preBuild process and that worked without issues for a month or so, then just suddenly out of the blue it failed today.

How are you doing this? What's the cleanest way to do this where we are not spending build time on installing more than needed while still getting this package installed? If you have the golden solution here, then I would thank you by adding it to the README as a PR for this repository so others may have an easier time getting it set up. At the same time I may also add a bit of a Q&A that explains how DynamoDB reacts and handles this stuff.

Hello, I'm having this error after npm installed the lib and added the @retain directive to my model:

An error occurred when pushing the resources to the cloud
🛑 An error occurred during the push operation: /
ctx.getResource is not a function

Here is what I have done:

• run: npm install --save graphql-retain-transformer on the root folder of the project
• added:

"transformers": [
   "graphql-retain-transformer"
] 

to transform.conf.json: the file is like that now:

{
    "Version": 5,
    "ElasticsearchWarning": true,
    "ResolverConfig": {
        "project": {
            "ConflictHandler": "AUTOMERGE",
            "ConflictDetection": "VERSION"
        }
    },
    "transformers": [
        "graphql-retain-transformer"
    ]
}

• Added the retain directive to my model in graphql schema, the model is like this:

type Route @model @auth(rules: [{allow: public}]) @retain{
  id: ID!
  cost: Float
  startTime: AWSTimestamp
  endTime: AWSTimestamp
  status: RouteStatus
  name: String!
  orders: [MpsOrder] @hasMany(indexName: "byRoute", fields: ["id"])
  driver: Driver @hasOne
}

• run: amplify push dev

Error:
✖ An error occurred when pushing the resources to the cloud
🛑 An error occurred during the push operation: /
ctx.getResource is not a function

What I've done wrong, anyone else got this error before ?

Thank you!
