Send pdfs to multiple users script

Development

$ yarn
$ tsc --watch

Google mail credentials

Get the needed credentials json file saved locally, and then change the path in index.ts to point correctly at this file.

Format the mail

All variables can be found in the index.ts file.

• Change the messagePlainText and messageHtml variables to fit your event.
• Change replyTo email if neccesary
• Change the subject if neccesary

Get the files you need

Create a folder named input, and change directory into it. Then proceed with the next step.

Pdfs from gogift

This is specific for the actual use-case of the program. From gogift half then job is getting the pdfs downloaded from their .csv. This is not integrated in the program, but can be done with some quick shell commands.

# The link to the pdf is the last column in each row, so we awk that and wget each link into ./pdfs
$ cat gogift.csv | awk -F ';' '{print $NF}' | wget --no-check-certificate -E -H -k -K -p -e robots=off -Ppdfs -nH --cut-dirs=3 -i -

# The files have no .pdf ending and have a long name so we can rename them
$ counter=0; for file in pdfs/*; do [[ -f $file ]] && mv -i "$file" $((counter+1)).pdf && ((counter++)); done

The steps above will result in a folder called pdfs with all the pfds in them, named n.pdf

Emails for the attendees

Download the json file from the event on https://old.online.ntnu.no, then place the file inside the input folder that you have created and rename it to "attendees.json"

Your filestructure should look like this now:

Production

# Get deps and build .js from .ts
$ yarn
$ yarn build

--ooccation	-O	Reason/Event for sending
--from_email	-E	Mail of the sender (Has to be in the bedkom g-suite group to work)
--pdfs	-P	Path to folder with pdfs

Check parsing and continue

The script will simply merge/fold/zip one email with one pdf.

1. If emails > pfds it will throw an error
2. If emails < pdfs it will simple not use the rest of the pdfs

Example

When starting the script it will will show the targets and ask for Y or yes to continue.

The from_email has to be an email in the bedkom g-suite group to work.
