Prisma is a next Generation ORM for NodeJS amp TypeScript Environments It has multiple databases support such as MySQL SQLite PostgreSQL MSSQL and also MongoDB Source PrismaSo in this post let s talk about the all new Prisma MongoDB Connector it s operations and what made me switch from Mongoose to Prisma for MongoDB ConnectionLet s start by establishing the connection to our MongoDB Server In your Prisma schema file we need to change the provider datasource db provider mongodb url env DATABASE URL The prisma schema file allows us to specify how we want Prisma to connect to our database We need to tell it what kind of provider we would like to use in this case mongodb and a url to connect to this is pointing to an environment variable as we want to keep it secret We will use a MongoDB connection string as the DATABASE URL which can be found in the prisma env file Next we need to setup the generator block like below generator client provider prisma client js previewFeatures mongoDb Since Prisma MongoDB Connector is still in preview we need to explicitly specify the previewFeatures key Defining ModelsSo now that connection has been successfully established to MongoDB Server let s now create models for our database collection A typical MongoDB document looks like this id oid dcbeffcad email somsubhra email com name Somsubhra So now how to define a model like this in Prisma Inside Prisma schema file we can define our models model User id String id default dbgenerated map id db ObjectId email String unique name String Comparing it with mongoose models in Mongoose ODM we would have written something like const mongoose require mongoose const Schema mongoose Schema const UserSchema new Schema name String email type String unique true module exports User mongoose model user UserSchema In Prisma we may also generate ObjectIds manually by using the bson package import ObjectId from bson const id new ObjectId Queries amp Database OperationsNow let s understand how to write queries and operations to MongoDB using Prisma in comparison to Mongoose Fetching Single recordFetching a single record in prisma is done using the where property but in mongoose it has findById method Prismaconst user await prisma user findUnique where id Mongooseconst result await User findById ebaed Fetching selected values for single recordFetching selected values for single record is easier than ever in Prisma ORM by using just a single query function to do the select operation whereas in Mongoose after finding the record we need to chain the output with select This increases the time complexity and also slows down the process Prismaconst user await prisma user findUnique where id select name true Mongooseconst user await User findById ebaed select name email Fetching relationsIn Prisma we use the include property but in Mongoose we would have to use the populate method Prismaconst posts await prisma user findUnique where id include post true Mongooseconst userWithPosts await User findById id populate posts Filtering with valuesIn Prisma we filter records using the where property whereas in Mongoose we use the find Prismaconst posts await prisma post findMany where title contains Hello World Mongooseconst user await Post find title Hello World Relation Filtering PrismaPrisma can filter a list based on a criteria that applies not only to the models of the list being retrieved but to a relation of that model const posts await prisma user findMany where Post some title contains Hello MongooseMongoose doesn t offer this feature for relation filters We may achieve similar functionality by adding an additional step to filter the results returned by the query but that would result in increased query times and load for large databases Pagination PrismaCursor style pagination const page prisma post findMany before id last Offset pagination const cc prisma post findMany skip first MongooseMongoose also has similar implementation for pagination const posts await Post find skip limit Creating Records Prismaconst user await prisma user create data email user email com Mongooseconst user await User create name John email user email com Updating RecordsPrisma updates the record directly with the values passed in data property in comparison with mongoose where we need to use set operator Prismaconst user await prisma user update data name John where id Mongooseconst updatedUser await User findOneAndUpdate id id set name John Deleting Single Record Prismaconst user await prisma user delete where id Mongooseawait User findByIdAndDelete id Deleting Multiple Records Prismaconst users await prisma user deleteMany where id in Mongooseawait User deleteMany id in Advantages of Prisma over MongooseSo now that we know the differences in operations between Prisma amp Mongoose let s now focus on the advantages Prisma provides over Mongoose Prisma allows TypeSafe Database access Prisma has an auto generated query builderSupport for multiple databases This is a huge advantage to developers when moving between SQL and NoSQL Databases since only the Schema file needs to be changed All other operations queries remain same Supports multiple RDBMSRobust migration capabilitiesPrisma lets you filter a list based on a criteria that applies not only to the models of the list being retrieved but to a relation of that model Mongoose doesn t offer a dedicated API for relation filters You can get similar functionality by adding an additional step to filter the results returned by the query Prisma Studio tool that helps to manage data easily Disadvantages of PrismaOn the other side Prisma has a few disadvantages over Mongoose as well Support for multiple model files not available All models need to be written in schema prisma file which makes the file cluttered and hard to debug and read Prisma MongoDB support is currently in previewCurrently no embedded collection support Error handling is incomplete The Migrate and Introspection workflows are currently not supported id and auto increment are not currently supported Should you be using Prisma over Mongoose Prisma is a modern ORM which has its own tradeoffs If you are building a server side application with REST APIs and GraphQL Prisma would be a great choice It also makes lives of developers easier Prisma gives a significant productivity boost for the most common database workflows If these factors don t matter much to you and you want to have more control over database operations then my suggestion will be to go with Mongoose for the time being

海外TECH	DEV Community	How Unix commands works	https://dev.to/____marcell/how-unix-commands-works-4jic	How Unix commands worksIf after using these commands for years you ever wondered how they work this is a high level exploration of someone who just had the some thoughts some days ago this is the result of my exploration I hope you learn something from it and get more interested in OS development in general first of all a little bit of history all theses programs are originally part of the gnu os the first atempt to create a free os they were written in the mid eighties and are older than Linux itself they were developed for unix than ported to Linux and are posix compliant ls in particular is part of coreutils a separate module of the gnu os you can see coreutils source code here Most of gnu os was developed by Richard Stallman the original neckbeardGNU Coreutils is used by most Linux distribution and you can even use it on Mac OS and Windows in Mac Os you can even replace the propietary coreutils As you might know Linux is not a OS Linux is just a kernel you need higher level programs to use your system that s why people sometimes refer to Linux as GNU Linux because it s the kernel with the other utilities necessary to realistically use the system in your day to day activities otherwise you would have to implement everything yourself I m gonna focus on how ls is implemented on top of the kernel if you wanna know what happens right after you type ls in your terminal you should read this amazing explanation How ls worksYou can see ls source code here this blog posts focuses on explaining ls but all other core utilities work in a similar fashion let s get to it the core functionality of ls are actived using two lower level functions opendir and readdir opendir opens a directory which is really just a file in Linux like everything else and readdir reads this file line by line each line as you might have guessed is the directory contents plus and which is used by the system to reference this directory and where this directory is if you search for these functions in src ls c you would find this DIR dirp struct dirent next dirp opendir name line for opendir while next readdir dirp line if next for readdirAs you might have guessed this while loop is ls s core functionality it s the part that reads the file entries in the dir and prints them out or do whatever it needs to do depending on the options that you pass to ls all other stuff in the source code is error handling parsing and applying options ls has a ton a options that accumulated over the years if we remove all these options we could implement ls with just a few lines of code so let s do that include lt stdio h gt include lt dirent h gt int main DIR folder struct dirent entry folder opendir if folder NULL return while entry readdir folder printf s entry gt d name printf n closedir folder return if we compile and run our ls version we get thisas you can see the output it s pretty similar to gnu ls already the only difference in this case is that ls is color coding different file types in my system and ls by default don t display and Ok now we have a pretty good understanding of how ls is implemented and the main libraries that it uses stdio h and dirent h but where does these libraries come from we need to dig deeper glibc and system callsstdio h and dirent h and pretty much anyother c library installed in your system lives in usr include stdio and dirent in particular are installed when you install glibc yet another gnu project printf comes from stdio opendir and readdir comes from dirent just like ls these functions are abstraction to make it easier to do the things that you want to do in your system actually everything is a abstraction all the way down ls is a application that uses glibc glibc itself make some system calls as you can see in the graph we don t necessarily need to use glibc to implement ls we could make the system calls ourselves let s do that include lt linux fs h gt u Buff int fd memset Buff x sizeof Buff mm segment t old fs get fs set fs KERNEL DS fd sys open etc Info O RDONLY if fd gt sys read fd Buff printk string s n Buff sys close fd set fs old fs Kernel level and User levelThe ls clone that we wrote is running on user level all the functions that we used opendir readdir and printf are user level functions a lot of things are restricted at user level functions at user level call other functions at kernel level this is what we call a system call so the function opendir for example eventually will call sys open which is a system call that it self calls do sys open which is a kernel level function the kernel is actually what comunicates with devices and the cpuThe kernel is a program that is always in memory and facilitates the comunication between the hardware and applications one of these utilities is the functions that we just used we could go deeper and explore how do sys open is implemented at kernel level but that s propably another post As you can see it s a lot harder to understand the sys call version and you do very little with a lot of code as you get closer to the kernel you have to deal with internal calls of the system that s the reason why the kernel exists it s a abstraction on top of the machine so you don t have to deal with all this low level stuff you can see in the code that we have to make a lot of different system calls just to read a directory if you wanna go deeper and learn even more about how linux works I recommend this book this book I m reading it and it s pretty good	2021-07-29 16:39:09
海外TECH	DEV Community	Realtime Rails with websockets	https://dev.to/ndrean/realtime-rails-with-websockets-1jk3	Realtime Rails with websocketsYet another tuto on Rails framework ActionCable I focus on going quickly to the relevant paths to achieve running a rails app with a realtime feature packaged as a standalone process Instead of a traditional chat app this one simulates managing realtime inventories It has a button that on click increments a counter and broadcasts the decremented total this simulates a customer fulling his basket and decreasing accordingly the visible stock to any other connected customer We will setup the backend and the frontend The frontend requires the installation of the npm package actioncable and the backend to enable the middleware action cable engine npm actioncableRails guidesThe frontend is managed by React and the Websockets are managed by the integrated framework ActionCable The process is the following on the frontend implement a component with a button that triggers a POST request to a Rails backend endpoint a Rails controller method responds to this route It should save the new value customer to the database calculate the new stockbroadcast the total to a dedicated websocket channelin the frontend React component we update the state of the stock on each page refresh a GET request to the database when receiving data through the dedicated websocket channel The frontend component Button jsx looks like Button jsximport React useState useEffect from react import csrfToken from rails ujs other imports const Button gt const

const CounterChannel consumer subscriptions create channel CounterChannel connected disconnected received data Called when there s incoming data on the websocket for this channel export default CounterChannel In the Button component we will mutate the state of the counter On page refresh we fetch from the database and mutate the state for rendering and when we receive data on the websocket channel we also mutate the state for rendering To do this we pass a function to the CounterChannel received that mutates the state If we don t have any data then we mutate the state with a GET request This is done wition a useEffect hook We can complet the Button component with import CounterChannel from channels counter channel js const Button gt const counters setCounters useState useEffect gt
