            apollo Key Features

            Unified management of the configurations of different environments and different clusters Apollo provides a unified interface to centrally manage the configurations of different environments, different clusters, and different namespaces The same codebase could have different configurations when deployed in different clusters With the namespace concept, it is easy to support multiple applications to share the same configurations, while also allowing them to customize the configurations Multiple languages is provided in user interface(currently Chinese and English)
            Configuration changes takes effect in real time (hot release) After the user modified the configuration and released it in Apollo, the sdk will receive the latest configurations in real time (1 second) and notify the application
            Release version management Every configuration releases are versioned, which is friendly to support configuration rollback
            Grayscale release Support grayscale configuration release, for example, after clicking release, it will only take effect for some application instances. After a period of observation, we could push the configurations to all application instances if there is no problem
            Authorization management, release approval and operation audit Great authorization mechanism is designed for applications and configurations management, and the management of configurations is divided into two operations: editing and publishing, therefore greatly reducing human errors All operations have audit logs for easy tracking of problems
            Client side configuration information monitoring It's very easy to see which instances are using the configurations and what versions they are using
            Rich SDKs available Provides native sdks of Java and .Net to facilitate application integration Support Spring Placeholder, Annotation and Spring Boot ConfigurationProperties for easy application use (requires Spring 3.1.1+) Http APIs are provided, so non-Java and .Net applications can integrate conveniently Rich third party sdks are also available, e.g. Golang, Python, NodeJS, PHP, C, etc
            Open platform API Apollo itself provides a unified configuration management interface, which supports features such as multi-environment, multi-data center configuration management, permissions, and process governance However, for the sake of versatility, Apollo will not put too many restrictions on the modification of the configuration, as long as it conforms to the basic format, it can be saved. In our research, we found that for some users, their configurations may have more complicated formats, such as xml, json, and the format needs to be verified There are also some users such as DAL, which not only have a specific format, but also need to verify the entered value before saving, such as checking whether the database, username and password match For this type of application, Apollo allows the application to modify and release configurations through open APIs, which has great authorization and permission control mechanism built in
            Simple deployment As an infrastructure service, the configuration center has very high availability requirements, which forces Apollo to rely on external dependencies as little as possible Currently, the only external dependency is MySQL, so the deployment is very simple. Apollo can run as long as Java and MySQL are installed Apollo also provides a packaging script, which can generate all required installation packages with just one click, and supports customization of runtime parameters

            Vue 3, GraphQL, Apollo - How to re-render query when cache changes?
            Asked 2022-Mar-31 at 11:33

            I would like to know how to build Vue 3 Apollo apps with queries and mutations. I'm familiar with react useQuery hook. It re-renders the component whenever the cached data has been changed (by mutations).

            I have tried:

            In all cases it just loads the data once and doesnt react to cache data changes.

            I undestand that I can build own setup by Apollo client or refetch the queries. I can even invalidate components by its keys. This is not really as elegant as the React useQuery hook is.

            I was curious whether there is any ready-made solution and the best practice for smooth graphql operations in Vue 3.

            I have misconfigured the schema and cache update. So the answer is that it works well.

            Duplicate active queries in Apollo Client Devtools
            Asked 2022-Feb-28 at 17:33

            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

            Answered 2022-Feb-28 at 17:33

            This 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.

            Answered 2021-Sep-16 at 13:35

            At the time of release of Apollo Server 3, the protocol used in the graphql-ws library is not yet supported by GraphQL Playground or Apollo Explorer.

            see here

            It's only advisable to use graphql-ws if interacting with subscriptions via playground is not of much use to you and you're okay interacting with subscriptions solely from your own client that has been setup to use graphql-ws.

            To setup your client to use graphql-ws with Apollo. see here.

            AWS Graphql lambda query
            Asked 2022-Jan-09 at 17:12

            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



            Answered 2022-Jan-09 at 17:06

            TL;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:

            Testing React Component with React Router V6
            Asked 2022-Jan-02 at 08:29

            I understand that React Testing Library has an example of testing with react router, but I couldn't get it to work (I think because I am using react router V6).

            Basically, I need router testing because I have details component that uses useParams() to get part of the url. I can't render the component without it.

            This was my attempt to make it work (yes the page also needs apollo, although it doesn't really need redux).
