Fragments let you group a list of children without adding extra nodes to the DOM. // your code provides a wrapper to wrap all your elemnts inside it.What it basically means is all components should be wrapped in a parent element. A common pattern in React is for a component to return multiple elements. In react <> and </> is just a syntactic sugar for .This can result in a delayed response, and it drastically reduces the likelihood that the query's result can be reused by a server-side response cache. If instead your root component executes a single, enormous query to obtain data for all of its children, it might query on behalf of components that aren't even rendered given the current state. Each component can (and should) query exactly the field s it requires to render, with no superfluous data sent over the network. One of GraphQL's biggest advantages over a traditional REST API is its support for declarative data fetching. Query only the data you need, where you need it If you are using newer version of react via CRA and Gatsby. I tried rendering simple html code such asbar But the issue remains.My api query works fine and I can get the data I'm after but I'm struggling displaying it in the component. I dont get any errors in the console as well. Here's my React component below, can anyone understand why the react.Fragment doesn't render at all in the getResults function I'd like it to eventually display the results from the api response. Exactly you right, new XML / JSX syntax fragment, hence <></> needs to run with babel version 7. My problem is, the components Im returning inside are not rendering. You can also specify which variable values (if any) are included in metrics reporting to Apollo Studio. As per the documentation, the syntax <></> is not supported by all tools and they encourage you to use instead.Variable values are not included in query strings. sometimes you might want to use a shorter syntax. We know that we make use of the render method inside a component whenever we want to render something to the screen. Use JavaScript operators like if or the conditional operator. Conditional rendering in React works the same way conditions work in JavaScript. depending on the state of your application. If this information is included in a query string, it's cached with the rest of that query string. In React, you can create distinct components that encapsulate behavior you need. The value of a GraphQL argument might include sensitive information, such as an access token or a user's personal info. Decomplected: Rum is a library, not a framework. Hardcoded argument s reduce the performance gains of these features and take up useful space in the cache. Simple semantics: Rum is arguably smaller, simpler and more straightforward than React itself. The server-side cache also powers features like automatic persisted queries and query plans in a federated gateway. The cache enables your server to skip parsing and validating operation s that it's encountered before, improving performance. If two otherwise identical queries have different hardcoded argument values, they're considered entirely different operations by your GraphQL server's cache. Copy Disadvantages of hardcoded GraphQL argumentsīeyond reusability, hardcoded argument s have other disadvantages relative to variable s: Reduced cache effectiveness
