Ghosler - Ghost Newsletters 👻

Ghosler enables easy sending of newsletters using your own email and SMTP credentials.\ This is ideal when you are just starting out and have a small to moderate user base.

It is helpful for bypassing the limitations of the hardcoded Mailgun setup and supports many analytical features, along with the capability to use multiple email accounts.

Running Ghosler

1. Installation with NPM

Pre-requisites: Node 18^ & pm2 installed.

1. Install the CLI -

   npm install -g ghosler-cli

2. Go to the directory you want to install Ghosler, make sure its empty & run below command -

   ghosler install

2. Installation with Docker

Execute this script to install or update Ghosler via Docker -

curl -sSL https://raw.githubusercontent.com/ItzNotABug/ghosler/master/docker-install.sh -o docker-install.sh && chmod +x docker-install.sh && ./docker-install.sh

If you already have docker-install.sh on your system, simply execute -

./docker-install.sh

Now navigate to main site & edit required settings after completing the Setup instructions below.

Setup Instructions

1. Access Ghost Dashboard: Navigate to your Ghost dashboard.
2. Create Custom Integration:
   • Go to Settings > Advanced > Integrations.
   • Click on Add Custom Integration.
   • Name the integration (e.g., Newsletters) and click Add.
   • Copy the Admin API Key displayed.
3. Configure Ghosler:
   • Fire up the Ghosler front-end by going to https://your-domain.com.
     • Default PORT is 2369
     • Default login credentials are - Username: ghosler, Password - admin
   • Click on Settings button.
   • Click on Ghost Settings & add your Ghost Site Url & Admin API Key.
   • Add mail configurations in Emails section.
   • Change other settings you wish to and click Save Changes. Upon clicking Save Changes, Ghosler will automatically create a new Webhook in the Ghost Integration (if it doesn't already exist). This webhook enables Ghosler to receive information about posts when they are published.
4. Only publishing a Post: If you want to only publish a post & not send it via email, just add the #GhoslerIgnore tag to a post. The internal tag is created for you on the initial setup.

Now as soon as you publish your Post, it will be sent to your Subscribers who have enabled receiving emails.

Testing Configurations

Ghosler defaults to using a local configuration file, config.local.json, if it exists. The structure of this file is identical to that in config.production.json file.

Note: config.local.json should be placed inside the configuration directory.

Local Builds: Make sure to execute -

    npm run buildcss

to generate a minified css if you changed any .ejs files. If you don't, CSS based changes won't take effect. This also makes sure that the final CSS bundle includes only what's needed.

And use below to run Ghosler -

    npm run dev

You can use below for combining the above commands -

    npm run cleanstart

Building the Docker Image -

docker build -t ghosler . --no-cache

After a successful local build, run the container -

docker run --rm name ghosler -d -p 2369:2369 -v ghosler-logs:/usr/src/app/.logs -v ghosler-analytics:/usr/src/app/files -v ghosler-configuration:/usr/src/app/configuration ghosler

Note: For testing the Docker container over a publicly accessible URL, I used Cloudflare Tunnel as it doesn't have a startup page like ngrok or the VSCode's dev tunnel and works good for testing the Ghost Webhooks.

Assuming you have TryCloudflare CLI installed, you can do something like this -

cloudflared tunnel --url http://localhost:2369

This command will initialize a tunnel and return a URL that you can use to test.\ For more info, see - TryCloudflare Tunnel.

Custom Template

If you want to customize the newsletter template even more, follow the steps -

1. Create a custom-template.ejs
2. Customize it as you like, for reference - you can download the Base Template from settings itself
3. Upload it via dashboard & that's it! Ghosler will use the new template for preview & sending newsletter
4. Disable from settings if you don't want to use the custom template

And don't forget to ⭐ the project!
