+const dbgatePluginCsv = require("dbgate-plugin-csv");
+
+dbgateApi.registerPlugins(dbgatePluginCsv);
+
+
+async function run() {
+  const reader = await dbgateApi.fakeObjectReader();
+  const writer = await dbgatePluginCsv.shellApi.writer({ fileName: 'myfile1.csv', separator: ';' });
+  await dbgateApi.copyStream(reader, writer);
+  
+  console.log('Finished job script');
+}
+dbgateApi.runScript(run);
+
+
+```
