海外TECH	DEV Community	Fula: a new, innovative way to develop decentralized applications	https://dev.to/fx/fula-a-new-innovative-way-to-develop-decentralized-applications-dp0	Fula a new innovative way to develop decentralized applicationsGreetings fellow DEVs First off a warm thank you to the DEV TO community for all the support they ve given Functionland As a relatively new member of the dev team I can tell you that ben s comment on our previous post was one of the first things I read when I discovered this project A lot has changed since then Time for an update Hopefully we can garner EVEN MORE support from you now in the final days of our crowdfunding campaign Before I get to the updates I d like to share what first resonated with me about the Fula protocol the open source pp protocol we mentioned in the last DEV TO update Before joining Functionland I wanted to learn more about web So I joined an eth global hackathon There I worked on a token gated livepeer video streaming site that creators could use to host an online ticketed concert I was a little disappointed when I learned that the status quo for access control in web still tended to be centralised relying on a single node to verify that the NFT holder matches their wallet address I felt let down The appeal of writing networked permissionless software vanished I d discovered I had to be a bridge keeper to users of my “DApp This meant I d have to set up my own cloud account and monitor usage and make sure that if usage spikes I have a way to pay the bills It also meant that I couldn t really claim permissionless anymore because at any moment I could pull the plug I went down a bit of a rabbit hole looking for better decentralized solutions that would enable me a third party DApp developer to get out of the way After all isn t that the big promise of web Always on permissionless computing I looked into a lot of decentralized computing projects and came to two conclusions When it comes to using a surrogate for my own computations I don t think it s possible to completely remove trust There is no such thing as free energy If someone is offering free cloud computing there must be a catch Then I discovered Functionland What resonated with me was the fact that the team was building a solution Box for people to replace cloud computing with something new not just another native cloud solution The Functionland team was proposing a completely new paradigm hybrid cloud on prem computing for consumers with customized plug and play hardware so that they don t have to compromise on convenience This solution continues to offer the properties of cloud that consumers take for granted like availability and reliability It also offers consumers new elements that cloud alone can t provide truly permissionless DApps The developer doesn t have to hold any API keysadditional security and privacy The user can choose to run everything on their own hardwarecomplete data ownership Everything I upload also sits on my own home serverLet s take a moment and a deep breath and appreciate the magnitude of offering a hybrid soolution for consumers Hasn t enterprise spent the last few decades migrating all of their data from their own servers to a cloud data centre to cut down on the cost of staffing their own sys admins Yes but any high paid sys admin out there can tell you many organisations have not and will not ever fully migrate all their data to the cloud Why Because there is certain data aka systems of record that is so important to the business that it isn t worthwhile to trust someone else with it So why do consumers need what only the largest enterprises have To answer that let s do a little thought experiment Let s say we came up with essentially the same solution from a system design perspective as the personal cloud storage providers except we use a decentralized storage network That s great because we are now enabling anyone with the technical know how to be a storage provider But what happens when you stop paying the bills and your device turns off You would have to call each individual storage provider s customer support and ask them to please hold on to your data in good faith even though you are behind on a bill That doesn t sound right to me Especially since we are talking about my personal home photos and video a big part of my legacy that I would like to some day pass down to my children So after rolling my eyes and saying to myself not another web protocol I began to understand the need for something new that not only takes advantage of the cutting edge in peer to peer networking but also acknowledges the fact that the client server architecture is also not going away which is incredibly important in a world full of low powered embedded devices Now…Let s get back to that update The dev team has been hard at work developing a usable Fotos DApp Fula the web protocol I ve been ranting about and Box it s reference implementation We ve also put a lot of time and consideration into a new consolidated docs site where interested externals can come to learn how to develop their own rich web DApps on top of Fularead our latest whitepaperlook at our latest designs for future work in the RFCs sectionThe Fula protocol was designed to power the Fotos DApp as a Web decentralised application using open interoperable specifications that include IPFS and libpp However it was not designed only for the purpose of backing up and sharing photos from a react native mobile client We also provide Todo Web Gallery and Doc syncing sample DApps to illustrate how developing DApps for web can be even easier than developing apps for web The TODOs sample DApp illustrates making CRUD operations over graphql and the gallery sample DApp illustrates how to use the FILE and GRAPH APIs in conjunction with each other Finally the doc syncing companion DApps illustrate the following how one can subscribe to and receive events in realtime using the Graph APIworking with different file formats besides photos such as plain text markdownhow updates to files can be shared in real time by intercepting file system change events provided by the underlying OS and acting on those changes by invoking the File APIhow a developer could add a simple deploy script that calls IPFS add r on the app s build output as a package json deploy script no cloud hosting account needed To learn how to get the samples running and how to work with the FULA client libraries developers can head over to the getting started section on docs fx land Recently besides refining the Graph and File APIs the team has made some first steps towards improving DApp availability and reliability with local pools by refactoring the Box architecture to include IPFS Cluster We have also included support for client side encryption through the use of decentralised identifiers DIDs That s it for the update We would like to acknowledge the technical mountain we are trying to overcome in a short amount of time There are incredibly smart people that have been working on the problem we are trying to solve for over a decade We believe we can get there in a relatively short amount of time because of the following laser focus on delivering what matters with the flagship DApps when we shipexceptional funding thanks to support from the open source development community that is YOU most importantly standing on the shoulders of giants from hardware to software Thanks and we really look forward to hearing feedback from the wonderful DEV TO community about what we are building As always please feel free to bash our idea We are still learning and we consider you all as frenz Frenz tell frenz when they have something stuck in their teeth

海外TECH	DEV Community	URL Shortener: Java & Spring complete tutorial	https://dev.to/marinsborg/url-shortener-java-spring-complete-tutorial-1aif	URL Shortener Java amp Spring complete tutorial IntroductionFor more posts like this follow me on TwitterA URL shortener is a service that is used to create short links from very long URLs Usually short links have the size of one third or even one fourth of the original URL which makes them easier to type present or tweet Clicking on a short link user will be automatically redirected to the original URL There are many URL shortening services available online like tiny cc bitly com cutt ly etc Implementing a URL shortening service is not a complex task and it is often part of system design interviews In this post I will try to explain the process of implementing the service TheoryBefore implementation it is always a good idea to write down what it is needed to be done in the form of functional and non functional requirements Functional requirements Users need to be able to enter a long URL Our service should save that URL and generate a short link Users should have the option to enter the expiration date After that date passed the short link should be invalid Clicking on the short link should redirect the user to the original long URL Users should create an account to use the service Service can have a usage limit per user User is allowed to create his own short link Service should have metrics for example most visited links Non functional requirements Service should be up and running of the time Redirecting should not last longer than two seconds Requirements are optionalUrl conversion Let s say that we want to have a short link with a maximum length of The most important thing in a URL shortener is the conversion algorithm URL conversion can be implemented in several different ways and each way has its pros and cons One way of generating short links would be hashing the original url with some hash function for example MD or SHA When using a hash function it is sure that different inputs will result in different outputs The result of the hash is longer than seven characters so we would need to take the first seven characters But in this case there could be a collision because the first seven characters could already be in use as a short link Then we take the next seven characters until we find a short link that is not used The second way of generating a short link is by using UUIDs The probability that a UUID will be duplicated is not zero but it is close enough to zero to be negligible Since a UUID has characters that means that we have the same problem as above We should take the first seven characters and check if that combination is already in use Third way would be converting numbers from base to base A base is a number of digits or characters that can be used to represent a particular number Base are digits which we use in everyday life and base are a z A Z This means that for example number in base with four digits would be the same number in base but with two characters Using base in url conversion with a maximum length of seven characters allows us to have unique values for short links So how base conversion works We have a base number that we want to convert to base We are going to use the following algorithm while number gt remainder number number number attach remainder to start of result collectionAfter that we just need to map numbers from the result collection to the base Alphabet a b c A B C Let s see how this works with a real example In this example let s convert from base to base st iteration number remainder number result list nd iteration number remainder number result list There is no more iterations since number after nd iterationMapping to base would be g This means that base gbase Converting from base to base is also simple i while i lt inputString lenght counter i mapped basealphabet indexOf inputString i map character to number based on its index in alphabet result result mapped inputString lenght counter i Real example inputString g inputString length i result st iteration counter mapped index of g in basealphabet is result nd iteration counter mapped index of in basealphabet is result ImplementationNote The whole solution is on my Github I implemented this service using Spring boot and MySQL We are going to use our database s auto increment feature The auto incrementing number is going to be used for base conversion You can use any other database that has an auto increment feature First visit Spring initializr and select Spring Web and MySql Driver After that click on Generate button and download zip file Unzip the file and open the project in your favorite IDE Every time I start a new project I like to create some folders to logically divide my code My folders in this case are controller entity service repository dto and config Inside the entity folder let s create a Url java class with four attributes id longUrl createdDate expiresDate Notice that there is no short link attribute We won t save short links We are going to convert the id attribute from base to base every time there is a GET request This way we are saving space in our database The LongUrl attribute is the URL we should redirect to once a user accesses a short link The created date is just to see when the longUrl is saved it is not important and expiresDate is there if a user wants to make a short link unavailable after some time Next let s created a BaseService java in the service folder BaseService contains methods to convert from base to base and vice versa private static final String allowedString abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ private char allowedCharacters allowedString toCharArray private int base allowedCharacters length Like I mentioned before if we want to use base conversions we need to have a base alphabet which in this case is called allowedCharacters Also the value of the base variable is calculated from the length of the allowed characters in case we want to change the allowed characters The encode method takes a number as input and returns a short link The decode method takes a string short link as an input and returns a number The algorithms should be implemented as they were explained above After that inside the repository folder let s create UrlRepository java file which is just an extension of JpaRepository and it gives us a lot of methods like findById save etc We don t need to add anything else to this Then let s create a UrlController java file in the controller folder The controller should have one POST method for creating short links and one GET method for redirecting to the original URL PostMapping create short public String convertToShortUrl RequestBody UrlLongRequest request return urlService convertToShortUrl request GetMapping value shortUrl public ResponseEntity lt Void gt getAndRedirect PathVariable String shortUrl var url urlService getOriginalUrl shortUrl return ResponseEntity status HttpStatus FOUND location URI create url build POST method has a UrlLongRequest as its request body It is just class with longUrl and expiresDate attributes The GET method takes a short url as a path variable and then gets and redirects to the original url At the top of the controller UrlService is injected as a dependency which will be explained next UrlService java is where most logic is and is the service used by the controller ConvertToShortUrl is used by the POST method from the controller It just creates a new record in the database and gets an id That id is then converted to a base short link and returned to the controller GetOriginalUrl is a method used by the GET method from the controller It first converts a string to base and the result of that is an id Then it gets a record from the database by that id and throws an exception if it does not exist After that it returns the original URL to the controller And that is it for part one In the next part I will focus on some more advanced stuff Advanced topicsIn this part I will talk about Swagger documentation dockerization of application application cache and MySql scheduled event Swagger UIEvery time you develop an API it is good to document it in some way Documentation makes APIs easier to understand and use The API in this project is documented using Swagger UI Swagger UI allows anyone to visualize and interact with the API s resources without having any of the implementation logic in place It s automatically generated with the visual documentation making it easy for back end implementation and client side consumption There are several steps that we need to do to include Swagger UI in the project First we need to add Maven dependencies to the pom xml file lt dependency gt lt groupId gt io springfox lt groupId gt lt artifactId gt springfox swagger lt artifactId gt lt version gt lt version gt lt dependency gt lt dependency gt lt groupId gt io springfox lt groupId gt lt artifactId gt springfox swagger ui lt artifactId gt lt version gt lt version gt lt dependency gt For reference you can see the complete pom xml file here After adding the Maven dependencies it is time to add Swagger configuration Inside the config folder we need to create a new class SwaggerConfig java Configuration EnableSwagger public class SwaggerConfig Bean public Docket apiDocket return new Docket DocumentationType SWAGGER apiInfo metadata select apis RequestHandlerSelectors basePackage com amarin build private ApiInfo metadata return new ApiInfoBuilder title Url shortener API description API reference for developers version build At the top of the class we need to add a couple of annotations Configuration indicates that a class declares one or more beans methods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime EnableSwagger indicates that Swagger support should be enabled Next we should add Docket bean which provides the primary API configuration with sensible defaults and convenience methods for configuration The apiInfo method takes the ApiInfo object where we can configure all necessary API information otherwise it uses some default values To make code cleaner we should make a private method that will configure and return the ApiInfo object and pass that method as a parameter the of apiInfo method In this case it is the metadata method The apis method allows us to filter packages that are being documented Now Swagger UI is configured and we can start documenting our API Inside UrlController above every endpoint we can use ApiOperation annotation to add description Depending on your needs you can use some other annotations It is also possible to document DTOs and using ApiModelProperty which allows you to add allowed values descriptions etc CachingAccording to Wikipedia a cache is a hardware or software component that stores data so that future requests for that data can be served faster the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere The most frequently used type of cache is in memory cache which stores cached data in RAM When data is requested and found in the cache it is served from RAM instead of from a database This way we avoid calling costly backend when a user requests data A URL shortener is a type of application that has more read requests than write requests which means it is an ideal application to use cache To enable caching in Spring Boot application we just need to add EnableCaching annotation in UrlShortenerApiApplication class After that in the controller we need to set the Cachable annotation above GET method This annotation automatically stores the result of the method call to the cache In the Cachable annotation we set the value parameter which is the name of the cache and the key parameter which is the cache key In this case for the cache key we are going to use shortUrl because we are sure it is unique Sync parameter is set to true to ensure only a single thread is building the cache value And that is it our cache is set and when we first load the URL with some short link the result will be saved to cache and any additional call to the endpoint with the same short link will retrieve the result from the cache instead of from the database DockerizationDockerization is the process of packaging an application and its dependencies in a Docker container Once we configure Docker container we can easily run the application on any server or computer that supports Docker The first thing we need to do is to create a Dockerfile A Dockerfile is a text file that contains all the commands a user could call on the command line to assemble an image FROM openjdk jdk alpine COPY target url shortener api SNAPSHOT jar usr src app url shortener api SNAPSHOT jar EXPOSE ENTRYPOINT java jar usr src app url shortener api SNAPSHOT jar FROM This is where we set a base image for the build base We are going to use OpenJDK v which is a free and open source version of Java You can find other images for your base image at Docker hub which is a place for sharing docker images COPY This command copies files from the local filesystem your computer to the filesystem of the container at the path we specified So we are going to copy the JAR file from the target folder to usr src app folder in the container I will explain creating the JAR file a bit later EXPOSE Instruction that informs Docker that the container listens on the specified network ports at runtime The default protocol is TCP and you can specify if you want to use UDP ENTRYPOINT This instruction allows you to configure a container that will run as an executable Here we need to specify how Docker will run out an application The command to run an application from the jar file is java jar lt app name gt jarso we put that words in an array and that is it Now when we have Dockerfile we should build the image from it But like I mentioned before we first need to create jar file from our project so the COPY command in Dockerfile can work properly To create executable jar we are going to use maven We need to make sure we have Maven inside our pom xml If Maven is missing we can add it lt build gt lt plugins gt lt plugin gt lt groupId gt org springframework boot lt groupId gt lt artifactId gt spring boot maven plugin lt artifactId gt lt plugin gt lt plugins gt lt build gt After that we should just run the command mvn clean packageAfter that is done we can build a Docker image We need to make sure we are in the same folder where a Dockerfile is so we can run this command docker build t url shortener latest t is used to tag an image In our case that means that the name of the repository will be url shortener and a tag will be the latest Tagging is used for the versioning of images After that command is done we can make sure we created an image with the command docker images That will give us something like this For the last step we should build our images I say images because we will also run MySQL server in a docker container Database container will be isolated from the application container To run MySQL server in docker container simply run docker run name shortener e MYSQL ROOT PASSWORD my secret pw d p mysql You can see the documentation on Docker hub When we have a database running inside a container we need to configure our application to connect to that MySQL server Inside application properties set spring datasource url to connect to the shortener container Because we made some changes in our project it is required to pack our project into a jar file using Maven and build the Docker image from the Dockerfile again Now that we have a Docker image we should run our container We do that with the command docker run d name url shortener api p link shortener url shortener d means that a Docker container runs in the background of your terminal name lets you set the name of your container p host port docker port This is simply mapping ports on your local computer to ports inside container In this case we exposed port inside a container and decided to map it to our local port link with this we link our application container with database container to allow containers to discover each other and securely transfer information about one container to another container It is important to know that this flag is now legacy and it will be removed in the near future Instead of links we would need to create a network to facilitate communication between two containers url shortener is the name of the docker image we want to run And with this we are done in browser visit http localhost swagger ui htmlNow you can publish your image to DockerHub and easily run your application on any computer and server There are two more things I want to talk about to improve our Docker experience One is multi stage build and the other is docker compose Multi stage buildWith multi stage builds you use multiple FROM statements in your Dockerfile Each FROM instruction can use a different base and each of them begins a new stage of the build You can selectively copy artifacts from one stage to another leaving behind everything you don t want in the final image Multi stage builds are good for us to avoid manually creating jar files every time we make some change in our code With multi stage builds we can define one stage of the build that will do the Maven package command and the other stage will copy the result from the first build to the filesystem of a Docker container You can see the complete Dockerfile here Docker composeCompose is a tool for defining and running multi container Docker applications With Compose you use a YAML file to configure your application s services Then with a single command you create and start all the services from your configuration With docker compose we will pack our application and database into single configuration file and then run everything at once This way we avoid running MySQL container and then linking it to the application container every time Docker compose yml is pretty much self explanatory first we configure MySQL container by setting image mysql v and credentials for the MySSQL server After that we configure the application container by setting build parameters because we need to build an image instead of pulling it like we did with MySQL Also we need to set that application container depends on the MySQL container Now we can run the whole project with only one command docker compose up MySql scheduled eventThis part is optional but I think somebody might find this useful anyway I talked about the expiration date of the short link which can be user defined or some default value For this problem we can set a scheduled event inside our database This event would run every x minutes and would delete any row from the database where the expiration date is lower than the current time Simple as that This works well on a small amount of data in the database Now I need to warn you about a couple of issues with this solution First This event will remove records from the database but it will not remove data from the cache Like we said before the cache will not look inside the database if it can find matching data there So even if data no longer exists in the database because we deleted it we can still get it from the cache Second In my example script I set that event runs every minutes If our database becomes huge then it could happen that event does not finish execution within its scheduling interval the result may be multiple instances of the event executing simultaneously	2022-05-04 20:16:10
