Answered 2022-Mar-25 at 07:05It sounds like you want to create a single executable artifact which requires no server-side configuration or setup to run.
There are a few options for this. You're probably looking for a Javascript bundler, like Rollup, Parcel or Webpack. Webpack is the most widely used, but also generally the most difficult to configure.
Using bundlers ParcelInstall Parcel with npm i -g parcel

QUESTION
I’m using React with Apollo Client 3 and Hasura as a GraphQL server.
The component ProductList
use the get_products
query once.
Then two exact copies of this query are memorized in the Apollo Cache as shown in the Apollo DevTools.
My question is - Why two identical queries get generated in the cache instead of one?
Apollo DevTools results

...ANSWER
Answered 2022-Feb-28 at 17:33This is basically a duplicate of Apollo Client what are active queries?
The main concept is that Active Queries represents the queries that are running inside of mounted components in your React application. It doesn't mean that the data is cached twice, it means that there are two places in your application that rely on the results of this query.
If the results of the query in cache are updated both places will automatically get the data updates.

The following query:

Answered 2022-Feb-22 at 21:24No it does not break the spec. The spec forces absolutely nothing in regards caching.
Literature for people that may be interestedFrom the end of the overview section
Because of these principles [... one] can quickly become productive without reading extensive documentation and with little or no formal training. To enable that experience, there must be those that build those servers and tools.
The following formal specification serves as a reference for those builders. It describes the language and its grammar, the type system and the introspection system used to query it, and the execution and validation engines with the algorithms to power them. The goal of this specification is to provide a foundation and framework for an ecosystem of GraphQL tools, client libraries, and server implementations -- spanning both organizations and platforms -- that has yet to be built. We look forward to working with the community in order to do that.
As we just saw the spec says nothing about caching or implementation details, that's left out to the community. The rest of the paper proceeds to give details on how the type-system, the language, requests and responses should be handled.
Also note that the document does not mention which underlying protocol is being used (although commonly it's HTTP). You could effectively run GraphQL communication over a USB device or over infra-red light.
We hosted an interesting talk at our tech conferences which you might find interesting. Here's a link:
GraphQL Anywhere - Our Journey With GraphQL Mesh & Schema Stitching • Uri Goldshtein • GOTO 2021
If we "Ctrl+F" ourselves to look for things as "Cache" or "ID" we can find the following section which I think would help get to a conclusion here:
ID The ID scalar type represents a unique identifier, often used to refetch an object or as the key for a cache. The ID type is serialized in the same way as a String; however, it is not intended to be human‐readable. While it is often numeric, it should always serialize as a String.
Result Coercion
GraphQL is agnostic to ID format, and serializes to string to ensure consistency across many formats ID could represent, from small auto‐increment numbers, to large 128‐bit random numbers, to base64 encoded values, or string values of a format like GUID.
GraphQL servers should coerce as appropriate given the ID formats they expect. When coercion is not possible they must raise a field error.
Input Coercion
When expected as an input type, any string (such as "4") or integer (such as 4) input value should be coerced to ID as appropriate for the ID formats a given GraphQL server expects. Any other input value, including float input values (such as 4.0), must raise a query error indicating an incorrect type.
It mentions that such field it is commonly used as a cache key (and that's the default cache key for the Apollo collection of GraphQL implementations) but it doesn't tell us anything about "consistency of the returned data".
Here's the link for the full specification document for GraphQL
Warning! Opinionated - My take on ID'sOf course all I am about to say has nothing to do with the GraphQL specification
Sometimes an ID
is not enough of a piece of information to decide whether to cache something. Let's think about user searches:
If I have a FavouriteSearch
entity that has an ID on my database and a field called textSearch
. I'd commonly like to expose a property results: [Result!]!
on my GraphQL specification referencing all the results that this specific text search yielded.
These results are very likely to be different from the moment I make the search or five minutes later when I revisit my favourite search. (Thinking about a text-search on a platform such as TikTok where users may massively upload content).
So based on this definition of the entity FavouriteSearch
it makes sense that the caching behavior is rather unexpected.
If we think of the problem from a different angle we might want a SearchResults
entity which could have an ID and a timestamp and have a join-table where we reference all those posts that were related to the initial text-search and in that case it would make sense to return a consistent content for the property results
on our GraphQL schema.
Thing is that it depends on how we define our entities and it's ultimately not related to the GraphQL spec
A solution for your problemYou can specify how Apollo generates the key for later use as key on the cache as @Matt already pointed in the comments. You may want to tap into that and override that behavior for those entitites that have a __type
equal to your masterVariant
property type and return NO_KEY for all of them (or similar) in order to avoid caching from your ApolloClient on those specific fields.
I hope this was helpful!
QUESTION
I have trouble setting up type hints for my JavaScript code using JSDoc (trying to make this work with VSCode and WebStorm).
As first step, I converted GraphQL schema into set of JSDoc @typedef
entries using @graphql-codegen/cli
. For the sake of this conversation, lets talk about this one:
ANSWER
Answered 2022-Feb-16 at 11:56While I was unable to make this work using just JSDoc, I had a good success using the same @graphql-codegen/cli
utility and generating .d.ts
file instead. After that, I was able to provide correct type hints using the following code:
QUESTION
The component renders the error state just fine, but the exception is displayed as uncaught in the console and a dialogue is displayed in next dev on the browser. Is there a way to handle expected errors to squelch this behavior?
...ANSWER
Answered 2021-Aug-08 at 04:30The error is from the client instead of the mutation so your try-catch cannot catch it. To handle this you can add the error handling to the client, for example:

I need to create a custom directive on INPUT_FIELD_DEFINITION to check if the provided value of the enum isn't being changed to the previous "state" (business logic is that states must go UNAPPROVED - > APPROVED -> CANCELLED -> FULFILLED) but can't quite figure out how to map values in constructor of the enum type.

QUESTION
I am not using AWS AppSync for this app. I have created Graphql schema, I have made my own resolvers. For each create, query, I have made each Lambda functions. I used DynamoDB Single table concept and it's Global secondary indexes.
It was ok for me, to create an Book item. In DynamoDB, the table looks like this: .
I am having issue with the return Graphql queries. After getting the Items
from DynamoDB table, I have to use Map function then return the Items
based on Graphql type
. I feel like this is not efficient way to do that. Idk the best way query data. Also I am getting null both author and authors query.
This is my gitlab-branch.
This is my Graphql Schema
...ANSWER
Answered 2022-Jan-09 at 17:06TL;DR You are missing some resolvers. Your query resolvers are trying to do the job of the missing resolvers. Your resolvers must return data in the right shape.
In other words, your problems are with configuring Apollo Server's resolvers. Nothing Lambda-specific, as far as I can tell.
Write and register the missing resolvers.GraphQL doesn't know how to "resolve" an author's books, for instance. Add a Author {books(parent)}
entry to Apollo Server's resolver map. The corresponding resolver function should return a list of book objects (i.e. [Books]
), as your schema requires. Apollo's docs have a similar example you can adapt.
Here's a refactored author
query, commented with the resolvers that will be called:
