Cannot find moudle 'sqlite3', please support

[newonejoe]

Hi @jctaoo, can you do me a favor to show how to use sqlite3 with this template. Install the sqlite 3 with following command yarn add sqlite3@5.0.0 --save. There is no problem during yarn dev . After yarn pack:mac or yarn pack:win, the building and packing is also successful. But there is always annoying error message: "Error cannot find module 'sqlite3'" after running the application

Nothing special in the ./src/main/utils/db.ts

import * as sqlite3 from 'sqlite3';
export const init = ()=> {
  let db = new sqlite3.Database('app.db');
  db.serialize(function() {
  db.run("CREATE TABLE if not exists lorem (info TEXT)");

  var stmt = db.prepare("INSERT INTO lorem VALUES (?)");
  for (var i = 0; i < 10; i++) {
      stmt.run("Ipsum " + i);
  }
  stmt.finalize();

  db.each("SELECT rowid AS id, info FROM lorem", function(err:any, row:any) {
      console.log(row.id + ": " + row.info);
    });
  });
  db.close();
}

After googling, there are lot of articles about electron-rebuild -f -w sqlite3. I add one line to package.json scripts "rebuild_sqlite3": "electron-rebuild -f -w sqlite3", and running yarn rebuild_sqlite3. It's working and generate napi-v{napi_build_version}-win32-x64 at \node_modules\sqlite3\lib\binding. Following is the log for rebuild_sqlite3

Can you demonstrate how to use sqlite3?

I’ll create a simple repo integrated with SQLite from this template later.

The problem is encountered in main process. This starter uses electron-run to build index.js of main process. Inside electron-run, it's esbuild. So you have to change the esbuild options in the node_modules/electron-run/build/main/src/commands/esbuild.js.

try {
        await esbuild.build({
            outdir: outDir,
            entryPoints: entryPoints,
            tsconfig: tsconfigPath,
            format: 'cjs',
            logLevel: 'silent',
            logLimit: 0,
            incremental: !isBuild,
            platform: 'node',
            sourcemap: true,
            bundle: true,
            external: externals,
            watch: !isBuild
                ? {
                    onRebuild: async (error) => {
                        if (error) {
                            reportError(...transformErrors(error));
                        }
                        else {
                            count++;
                            buildComplete(outDir, count);
                        }
                    },
                }
                : false,
        });
        count++;
        buildComplete(outDir, count);
    }

As you can see, the options of esbuild are not smart enough. The sqlite3 you imported is excluded in the bundle file. But you should only exclude the electron module. If you would use other modules in main process, you should change the external: external to external: ['electron'].
