Getting started

Upload several files in sequence

Example of how to iterate over a file list and call upload() for each one, with the session guaranteed on page load.

1 min read

upload() accepts a single File per call. To send several files — for example, every file chosen in an <input type="file" multiple> — iterate over the list and call upload() for each one. Each file in the batch must also follow the .json.gz format (gzip-compressed JSON Lines).

Example

html

<script src="https://cdn.infinity6.ai/releases/sdkweb/latest/bundle/i6sdk-web.js"></script>
<input type="file" id="files" multiple="" accept=".gz"/>
<script type="module">
  const sdk = window.I6Sdk;

  async function main() {
    // Guarantee the session before any upload.
    const user = await sdk.auth().requireUser();
    if (!user) return;

    document.querySelector("#files").addEventListener("change", async (event) => {
      for (const file of event.target.files) {
        try {
          await sdk.ingest().upload({
            dataset: "<your-dataset>",
            table: "<your-table>",
            partitions: { "<your-key>": "<your-value>" },
            file,
          });
          console.log(`Uploaded: ${file.name}`);
        } catch (error) {
          console.error(`Failed on ${file.name}:`, error);
        }
      }
    });
  }

  main();
</script>

Points of attention

Uploads happen in sequence, one at a time, which makes it easier to identify which file failed and resume from it.
Each iteration has its own try/catch, isolating errors per file so a single failure does not interrupt the upload of the remaining files.
