@devs-studio/kmp-js v1.0.12

This page is based on SQL.js Web Worker: https://sqldelight.github.io/sqldelight/2.0.2/js_sqlite/sqljs_worker/. Follow the instructions in that page before do this.

SQL.js Web Worker

To include the SQL.js worker in your project, first add a dependency on the worker package along with a dependency on SQL.js.

kotlin {
  sourceSets.jsMain.dependencies {
    implementation(npm("@devs-studio/kmp-js", "1.0.0"))
    implementation(npm("sql.js", "1.8.0"))
  }
}

The SQL.js package includes a WebAssembly binary that must be copied into your application's output. In your project, add an additional Webpack configuration file to configure the copying of the binary to your assembled project.

// {project}/webpack.config.d/sqljs.js
config.resolve = {
    fallback: {
        fs: false,
        path: false,
        crypto: false,
    }
};

const CopyWebpackPlugin = require('copy-webpack-plugin');
config.plugins.push(
    new CopyWebpackPlugin({
        patterns: [
            '../../node_modules/sql.js/dist/sql-wasm.wasm'
        ]
    })
);

Using the Worker

The worker script is called sqljs-custom.worker.js and can be referenced in code like this:

val driver = WebWorkerDriver(
  Worker(
    js("""new URL("@devs-studio/kmp-js/dist/sqldelight/sqljs-custom.worker.js", import.meta.url)""")
  )
)

See "Using a Web Worker" for more details.
