Integration driver for SQLDelight with sqlite3 native bindings, enabling suspending/async query APIs (awaitAsList/executeAsFlow), init helper and Gradle setup for binary bindings.
Driver for the library SQLDelight that supports sqlite3 Node.js module
Pretty much it's almost the same as with https://sqldelight.github.io/sqldelight/2.1.0/js_sqlite
Initialization of SQLDelight is needed
plugins {
kotlin("js") version "2.2.20" // probably would work even with different one
id("app.cash.sqldelight") version "2.1.0" // for version 0.5.0 and higher
}
፧
፧
፧
sqldelight {
databases {
create("Database") {
packageName.set("com.example")
generateAsync.set(true) // required for this driver!
}
}
}
Add dependency to the driver:
kotlin {
js {
binaries.executable()
nodejs {
dependencies {
implementation("cz.sazel.sqldelight:node-sqlite3-driver-js:0.5.0")
}
}
}
}
You'll also need to install binary bindings for SQLite3. This can be done by adding a special Gradle task that runs yarn
in the sqlite3 node package directory. It needs to run yarn first to download platform specific binary dependencies.
val bindingsInstall = tasks.register("sqlite3BindingsInstall") {
doLast {
val sqlite3moduleDir = layout.buildDirectory.get().dir("js/node_modules/sqlite3").asFile
if (!sqlite3moduleDir.resolve().exists()) {
exec {
workingDir = sqlite3moduleDir
yarnExecutable = yarn.environment.executable
yarnPath = file(yarnExecutable).parent
nodePath = file(kotlinNodeJsEnvSpec.executable).parent
environment(
, System.getenv() +
)
commandLine(yarnExecutable)
}
}
}
}.()
tasks[].finalizedBy(bindingsInstall)
Queries are written as here - https://sqldelight.github.io/sqldelight/2.1.0/js_sqlite/#using-queries
suspend fun main() {
val driver = initSqlite3SqlDriver(filename = "test.db", schema = Database.Schema)
val database = Database(driver)
val playerQueries: PlayerQueries = database.playerQueries
println(playerQueries.selectAll().awaitAsList())
// Prints [HockeyPlayer(15, "Ryan Getzlaf")]
playerQueries.insert(player_number = , full_name = )
println(playerQueries.selectAll().awaitAsList())
player = HockeyPlayer(, )
playerQueries.insertFullPlayerObject(player)
}
Note: Please use awaitAsList() or executeAsFlow() in queries instead of executeAsList()
as that API is not suspending and will throw an exception with this driver.
To Isuru Rajapakse and the project KStore which is an inspiration for the set-up of publishing in Gradle scripts.
To authors of SQLDelight, implementation is based on the sqljs implementation of the driver which is already included in the library.s.
