海外TECH	DEV Community	Efficiently Manage Your GraphQL API with API Gateway	https://dev.to/apisix/efficiently-manage-your-graphql-api-with-api-gateway-20p1	Efficiently Manage Your GraphQL API with API GatewayGraphQL is a powerful query language for APIs that allows developers to define the structure of the data they need from the server and the server responds with only that data This makes it much more efficient and flexible than traditional REST APIs which often require multiple requests to retrieve the same data However managing GraphQL APIs can be complex and time consuming especially at scale This is where an API Gateway comes in One of the key features of modern API Gateways such as Apache APISIX is its support for GraphQL APIs APISIX makes it easy to manage and scale GraphQL APIs using its flexible configuration system and powerful plugins One such plugin is the degrapghql plugin which allows us to convert the GraphQL API into a REST API In this post we will explore this feature with an example Learning objectivesYou will learn and find out answers to the following questions throughout the article What is the DeGraphQL plugin What are the use cases and features of the DeGraphQL plugin How to use the DeGraphQL plugin How to transform REST to GraphQL How to manage GraphQL API traffic Why use DeGraphQL plugin This plugin is able to transform APIs exposed by a GraphQL upstream backend service into a traditional REST endpoint by mapping URIs into GraphQL queries Calling REST APIs from a typical client opens the benefits of GraphQL for more people consider the following use cases Use case Your existing customers are used to consuming REST APIs and are not too familiar with how to write GraphQL queries In order to keep things simple for them you can use Apache APISIX API Gateway to convert GraphQL API to a REST API Use case You are in a front end development team that wants to try existing GraphQL API functionalities through REST API without asking for the back end team to implement a new GraphQL server Use case You have no access to change the backend because it s an existing set of GraphQL APIs potentially managed by a rd party Use case You have an existing REST API infrastructure but you re looking to evaluate whether GraphQL can work for your needs Use case You have a large codebase and the GraphQL migration is happening on the backend but you want to use GraphQL now without waiting Use case You have multiple microservices and they use the combination of both approaches You want to enable smooth communication between them What are the DeGraphQL plugin features DeGraphQL plugin provides a number of useful features that make it easy to configure and manage your GraphQL API including Request Validation It can validate incoming GraphQL requests to ensure they meet certain criteria This can include checking the structure of the query enforcing input type constraints and more By validating requests you can ensure that your API is always receiving valid and well formed requests Query Parsing It can also parse GraphQL queries allowing you to extract specific information from the query and use it to inform your API s behavior This can include things like selecting the appropriate backend service based on the requested data or modifying the response based on certain query parameters Response Transformation Finally it can transform GraphQL responses before they are returned to the client This can be useful for things like normalizing data structures removing sensitive information or adding additional data to the response With this capability Apache APISIX not only makes it easy to use REST and GraphQL together but you can also define rate limits enforce authentication and authorization block clients that attempt to misuse an API and ensure APIs work seamlessly as they are updated with help of other built in plugins How to use DeGraphQL plugin Demo With enough theoretical knowledge in mind now we can jump into a practical demo of DeGraphQL plugin DeGraphQL needs a GraphQL endpoint to query As an example we are going to use one of the free public GraphQL APIs that retrieve information about countries continents and languages If you navigate to the above Countries API link it will open a playground where you can write some queries against GraphQL API on the UI You can also build your own GraphQL API using StepZen or ApollographQL provided GraphQL studios that helps you build and deploy your own GraphQL API by combining prebuilt APIs such as Accuweather Airtable GitHub Twitter Trello and more For example you compose two Accuteweather and Countries APIs together to collect the weather information provided by a country city name and put APISIX at the front to query the API from REST Now our task is to transform the above query definition to a simple REST call and send it as JSON data As an outcome the Apache APISIX API Gateway exposes the REST endpoint and should be able to route all requests to the GraphQL API For example all REST requests to API Gateway country info URI path with an underlining query by a country code should be converted and passed to GraphQL countries API An example curl command that looks something like this curl i country info X POST d code EE And we should get a response from the API as follows data country code EE capital Tallinn currency EUR languages name Estonian In the next sections we will learn how to achieve this step by step Let s get Apache APISIX up and runningBefore you can use the degrapghql plugin you ll need to install Apache APISIX You can follow the installation instructions on the Apache APISIX website to get started PrerequisitesDocker is used to installing the containerized etcd and APISIX curl is used to send requests to APISIX for validation You can also use easy tools such as Postman to interact with the API APISIX can be easily installed and started with the following quickstart script curl sL shThis will create two Docker containers a etcd to store configuration and APISIX Gateway itself Once you see the “APISIX is ready message we can configure an upstream plugin and route via APISIX s Admin API that proxies requests to GraphQL API Create an UpstreamNext we will create an Upstream object to register our Countries GrapghQL API in the API Gateway curl apisix admin upstreams X PUT d name GraphQL API upstream desc Register Countries GraphQL API as the upstream type roundrobin scheme https nodes countries trevorblades com Create a Plugin ConfigNext a set up new plugin config object We will use two transformation plugins proxy rewrite and degraphql to rewrite the host and URI of the request and make a query to GraphQL API respectively curl apisix admin plugin configs X PUT d plugins proxy rewrite uri graphql host countries trevorblades com degraphql query query Country code ID country code code code capital currency languages name variables code In the above DeGraphQL plugin configuration we set two attributes such as query and variables GraphQL query variables can be defined on the Post request body or URIs in a REST call The query we re executing in this case looks like the following and you can replace it with your own query code ID country code code code capital currency languages name Create a Route with DeGraphQL pluginThis step involves setting up a new route that uses the plugin config and configuring the route to work with the upstream by referencing their IDs we created in the previous steps curl i apisix admin routes X PUT d name GraphQL API route desc Create a new route in APISIX for the Countries GraphQL API uri country info upstream id plugin config id Test DeGraphQL plugin activationNow let s test this new setup with the following curl command curl i country info X POST d code EE We will get response from APISIX data country code EE capital Tallinn currency EUR languages name Estonian The same code variable can also be provided as GET arguments curl i country info code EE Response TransformationWith the help of Apisix s response rewrite plugin it is possible to transform GraphQL responses before they are returned to the client Let s use this plugin to remove the currency key and value from the response JSON to show only everything else To do so we need to add the response rewrite plugin to the existing plugin configuration curl apisix admin plugin configs X PATCH d plugins response rewrite filters regex currency scope once replace vars status After this plugin is installed you can make a request to country info once again and see the transformed response data country code EE capital Tallinn languages name Estonian SummaryOverall the DeGraphQL plugin is an essential tool for any developer building a GraphQL API with APISIX It has powerful features and easy to use configuration making it a breeze to integrate into your existing API gateway while it supports GraphQL specific functionality ensures that your API is

海外TECH	DEV Community	Hashmaps	https://dev.to/codeninjausman/hashmaps-4p7	Hashmaps DefinitionHashmaps also known as hash tables or dictionaries are a fundamental data structure in computer science used to efficiently store and retrieve key value pairs In a hashmap each key is mapped to a specific value through a hash function which converts the key into a numeric index that is used to store and retrieve the associated value in an array like data structure called a bucket The process of adding a key value pair to a hashmap involves the following steps The hash function takes the key as input and produces a hash code which is an integer value that represents the key in a more compact and standardized form The hash code is then used to compute an index into the array like bucket structure where the value associated with the key can be stored If there is already a value stored at the computed index a collision has occurred and a collision resolution strategy is used to handle the collision and store the new value in a different bucket If there is no value stored at the computed index the new key value pair is stored in the bucket at that index When retrieving a value from a hashmap the process is similar The hash function is applied to the key to compute the hash code The hash code is used to compute the index into the bucket structure where the value should be stored The value at the computed index is returned or if there is no value stored at that index the key is not in the hashmap Hashmaps have several advantages over other data structures for storing key value pairs First they offer fast average case performance for accessing and retrieving values with a time complexity of O for both operations Second they can handle a large number of key value pairs without requiring significant amounts of memory Finally hashmaps are dynamic data structures that can be resized and rehashed as needed to accommodate changes in the number of key value pairs Implementationclass HashTable def init self size self size size self hash table self create buckets def create buckets self return for in range self size def set val self key val hashed key hash key self size bucket self hash table hashed key found key False for index record in enumerate bucket record key record val record if record key key found key True break if found key bucket index key val else bucket append key val def get val self key hashed key hash key self size bucket self hash table hashed key found key False for index record in enumerate bucket record key record val record if record key key found key True break if found key return record val else return No record found def delete val self key hashed key hash key self size bucket self hash table hashed key found key False for index record in enumerate bucket record key record val record if record key key found key True break if found key bucket pop index return def str self return join str item for item in self hash table Disadvantages However hashmaps also have some disadvantages The most significant issue is the possibility of collisions which can degrade the performance of the data structure if not handled properly Additionally hashmaps can be vulnerable to certain types of attacks such as hash collision attacks which can be used to overwhelm the bucket structure with intentionally crafted keys To address these issues hashmaps use various techniques for collision resolution such as chaining where multiple values are stored in the same bucket as a linked list or open addressing where additional buckets are probed until an empty bucket is found Additionally hash functions can be designed to minimize the likelihood of collisions or to be resistant to collision attacks	2023-03-22 07:21:07
