Multipart-POST Request Using Node.js

Multipart-POST Request Using Node.js

Here, I introduce 2 scripts for uploading files to Slack using Node.js as samples. These 2 sample scripts are for uploading files to Slack.

Sample script 1:

  • You can upload the zip file by converting byte array as follows.
    • At first, it builds form-data.
    • Adds the zip file converted to byte array and boundary using Buffer.concat().
    • This is used as body in request.
