海外TECH DEV Community Quick Start with the ReductStore JavaScript SDK https://dev.to/reductstore/quick-start-with-the-reductstore-javascript-sdk-172a Quick Start with the ReductStore JavaScript SDKThis quick start guide will walk you through the process of installing and using the ReductStore JavaScript client SDK to interact with a ReductStore instance Installing the SDKTo install the ReductStore SDK you will need to have Node js or higher installed on your machine Once Node js is installed you can use the npm package manager to install the reduct js package npm install reduct js Running ReductStore as a Docker ContainerIf you don t already have a ReductStore instance running you can easily spin one up as a Docker container To do so run the following command docker run p reductstore reductstoreThis will start a ReductStore instance listening on port of your local machine Using the SDKNow that you have the reduct js SDK installed and a ReductStore instance running you can start using the SDK to interact with the ReductStore instance Here is an example of using the JavaScript SDK to perform a few different operations on a bucket const Client QuotaType require reduct js const fs require fs const main async gt Create a client const client new Client Get or create a bucket with Gb quota const bucket await client getOrCreateBucket my bucket quotaType QuotaType FIFO quotaSize BigInt e The simplest case Write some data with the current timestamp let record await bucket beginWrite entry await record write Hello world More complex case Upload a file as a stream with a custom timestamp unix timestamp in microseconds const timestamp Date now record await bucket beginWrite entry timestamp const fileStream await fs createReadStream filename let s upload this file await record write fileStream fs statSync filename size The simplest case Read the data by a certain timestamp record await bucket beginRead entry timestamp console log await record readAsString More complex case Iterate over all records in the entry and read them as steams function streamToString stream const chunks return new Promise resolve reject gt stream on data chunk gt chunks push Buffer from chunk stream on error err gt reject err stream on end gt resolve Buffer concat chunks toString utf for await const record of bucket query entry console log Record timestamp record timestamp console log Record size record size Read the record as a stream await streamToString record stream main catch e gt console error e Let s break down what this example is doing Creating a ClientTo start interacting with the database we need to create a client You can use the Client class from the reduct module Pass the URL of the ReductStore instance you want to connect to as an argument to the Client constructor Create a clientconst client new Client Creating a BucketAll data in ReductStore is stored in buckets To get a bucket you can use the getOrCreateBucket method on aClient This method creates a bucket if it does not already exist Pass the name of the bucket you want to create along with the bucket settings In this example we are creating a bucket with a quota of Gb It means that the database willstart removing old data once the bucket reaches Gb Get or create a bucket with Gb quotaconst bucket await client getOrCreateBucket my bucket quotaType QuotaType FIFO quotaSize BigInt e Writing data to a BucketTo write data to a bucket you can use the beginWritemethod on a Bucket instance Pass the name of the entry youwant to write The beginWrite method returns a WritableRecord object that you can use to write data to the bucket The beginWrite method will use current time as the timestamp for the entry if it is not specified The simplest case Write some data with the current timestamplet record await bucket beginWrite entry await record write Hello world The WritableRecord write method accepts a ReadbleStream object as an argument so you can use it to write data from a file or any other source const timestamp Date now record await bucket beginWrite entry timestamp const fileStream await fs createReadStream filename let s upload this fileawait record write fileStream fs statSync filename size Pay attention that the write method has to know the size of the written data in advance Reading data from a BucketTo read data from a bucket you can use the beginRead method on a Bucket instance Pass the name and timestamp of the entry you want to read The beginRead method returns a ReadableRecord object with information about the record and method read to read the content The simplest case Read the data by a certain timestamprecord await bucket beginRead entry timestamp console log await record readAsString To iterate over all entry in a bucket you can use the query method on a Bucket instance More complex case Iterate over all records in the entry and read them as steamsfunction streamToString stream const chunks return new Promise resolve reject gt stream on data chunk gt chunks push Buffer from chunk stream on error err gt reject err stream on end gt resolve Buffer concat chunks toString utf for await const record of bucket query entry console log Record timestamp record timestamp console log Record size record size Read the record as a stream await streamToString record stream In this example we iterate over all entries in the bucket and read them as streams However you can use the startand stop arguments to specify a time interval for the records you want to retrieve The start argument specifies the beginning of the time interval and the stop argument specifies the end of the time interval Both arguments are timestamps in UNIX microseconds const startTs January at const stopTs January at for await const record of bucket query entry startTs stopTs console log Record timestamp record timestamp console log Record size record size console log Record content await record read Next StepsNow that you have a basic understanding of how ReductStore works you can start using it in your projects You can findmore information about the ReductStore JavaScript SDK here if you have any questions or feedback don t hesitate to reach out in
