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.

// Channel ID is on the the browser URL.: https://mycompany.slack.com/messages/MYCHANNELID/
// Pass it as a parameter: node ./delete-slack-messages.js CHANNEL_ID

// CONFIGURATION #######################################################################################################

const token = 'SLACK TOKEN';
// Legacy tokens are no more supported.
// Please create an app or use an existing Slack App

Ubuntu 16 – how to increase maximum file open limit ( ulimit -n )

If you are setting up nginx,chances are you will discover your worker_connections is at some low number, such as 1024. You can’t increase this number unless you increase kernel limit as well. First of all run cat /proc/sys/fs/file-max to discover your maximum limit.

abc@ubuntu:~$ cat /proc/sys/fs/file-max
1048576
abc@ubuntu:~$ ulimit -n
1024
