A local driver implementation for the LiquidKit file storage solution.
The local driver uses a local directory on the server and the FileManager object from the Foundation framework to store files. If you are planning to setup a distributed system with multiple application servers, please consider using the AWS S3 driver instead.
LiquidKit and the local driver is also compatible with Vapor 4 through the Liquid repository, that contains Vapor specific extensions.
Keys are being resolved using a public base URL component, the name of the working directory and the key itself.
publicUrl = "http://localhost/"
workDirectory = "assets"
key = "test.txt"
resolvedUrl = "http://localhost/assets/test.txt"
Add the required dependencies using SPM:
// swift-tools-version:5.3 import PackageDescription let package = Package( name: "myProject", platforms: [ .macOS(.v10_15) ], dependencies: [ .package(url: "https://github.com/binarybirds/liquid", from: "1.2.0"), .package(url: "https://github.com/binarybirds/liquid-local-driver", from: "1.2.0"), ], targets: [ .target(name: "App", dependencies: [ .product(name: "Liquid", package: "liquid"), .product(name: "LiquidLocalDriver", package: "liquid-local-driver"), ]), ] )
A basic usage example with SwiftNIO:
/// setup thread pool let elg = MultiThreadedEventLoopGroup(numberOfThreads: 1) let pool = NIOThreadPool(numberOfThreads: 1) pool.start() /// create fs let fileio = NonBlockingFileIO(threadPool: pool) let storages = FileStorages(fileio: fileio) storages.use(.local(publicUrl: "http://localhost/", publicPath: "/var/www/localhost/public", workDirectory: "assets"), as: .local) let fs = storages.fileStorage(.local, logger: .init(label: "[test-logger]"), on: elg.next())! /// test file upload let key = "test.txt" let data = Data("file storage test".utf8) let res = try fs.upload(key: key, data: data).wait() /// http://localhost/assets/test.txt let url = req.fs.resolve(key: key) /// delete key try req.fs.delete(key: key).wait()
