A Slack app written in Rust that converts an HTML to PDF and sends it to a user on Slack, i.e.:

• First, given an user email, get the user id (necessary to send the message).

• Second convert an HTML file to PDF.

• Third, send the PDF to the user on Slack.

How to use:

Create a Slack app at https://api.slack.com/apps and navigate to "OAuth & Permissions", then add the following permision are needed on Slack: chat:write, files:write, users:read and users:read.email and the same page look for "install the app on your workspace".

Next, create an .env file at the root of the repository (same folder as the Cargo.toml file) with:

    SLACK_OAUTH_TOKEN="slack_token_here"
    USER_EMAIL="user_email_here"

and run:

docker build . -t rust-slackbot-html-to-pdf && docker run --rm -it -v $(pwd)/.env:/app/.env -v path/to/file.html:/file.html rust-slackbot-html-to-pdf
