+# EdgeQL Query Builder (possibly) excessive build time and memory Issues
+
+This repository has been created to demonstrate the excessive memory consumption when transpiling the edgeql-js.
+
+|   |   |
+|---|---|
+| **OS** | Windows 11 |
+| **Node** | 20.14.0 |
+
+```bash
+npm install
+npm run db:reset
+npx tsc index.ts
+```
