Usage

Upload via multipart-upload

const CoreweaveTool = require("e3ds-cw-tools");

const cw = new CoreweaveTool({
  endpoint: process.env.NX_COREWEAVE_ENDPOINT,
  accessKeyId: process.env.NX_COREWEAVE_ACCESS_KEY_ID,
  secretAccessKey: process.env.NX_COREWEAVE_SECRET_ACCESS_KEY,
  region: "default"
});

(async () => {
  try {
    const result = await cw.uploadFile(
      "./builds/MyCoolApp_v1.0.zip",  // Local file path
      "exe-launchers",                 // Bucket name
      "aninda/MyCoolApp_v1.0.zip"     // Path inside bucket
    );
    console.log("File uploaded successfully:", result.Location);
  } catch (err) {
    console.error("Upload failed:", err);
  }
})();

Notes

Bucket must exist before uploading.

The uploader automatically uses multipart uploads for large files.

Works for even very large files (50GB+).

Do not commit your CoreWeave credentials; always use environment variables.
