Automating a Reading List

| posted in: nerdliness 

For a very long time I have been searching for, and trying, different note taking schemes in a futile effort to find a way to capture links to pages on the Internet. I wanted a way to find some previously read article or posting about “X”. Searching my browser history sometimes works, but not always. Creating a bookmark would only result in hundreds of bookmarks, and another searching problem. I view a bookmark as a way to return to a frequently visited site. For example, I have a book mark to Hacker News, but I don’t bookmark individual articles I find there.

On Hacker News recently there was a posting about tracking everything a person had read for a year. Underneath the statistics there was an automated way to, with a single click, capture a page you’ve read online. It works by using a JavaScript bookmarklet, some GitHub repository Actions, and a couple of Go language functions.

What You Need

JavaScript Bookmarklet

Copy the readingList.js bookmarklet Gist to your GitHub account. Make it a secret Gist as it will eventually have your GitHub Personal Access Token (PAT) included.

Fork the readingList repository

Fork the readingList repository created by codemicro. It was their idea, they deserve the forks. Once you have your fork, scrub through the code and replace all the references to codemicro with your GitHub ID.


The repository contains two GitHub Action workflows in the .github/workflows directory: append and build. Find the run line in both of these and update the path to point to your fork of the repository.

Additionally, in the append.yml file there is an email address for notifications; make sure to update it to your email address.



In the generator.go file, toward the end of the code, line 194 in my fork, there is an HTML link that needs to be updated to point to your readingList repository.


In the manager.go file you need to update the "" import to reference your repository.


Once you’ve finished updating all the code references to your ID or repository, rebuild the go.mod file. I deleted it and ran go mod init and the go mod tidy.


In the comments to the original readingList.js Gist, jamesmstone put links to his fork of the project. He added a new piece of JavaScript that allows you to use the bookmarklet without a server. In my case I’m using GitHub Pages to host the actual list page, the save.html code the jamesmstone created makes this possible.

Copy his save.html code to the .site directory in your fork of the project. On line 13 of the file, change his account name to yours.


The links are all appended to the readingList.csv file in the readingList repository. Unless you want all of codemicro’s articles, edit this file and delete all the lines except for the heading line.

GitHub Pages

In your readingList repository you need to setup GitHub Pages. Click on the Settings link in the navigation bar. I set mine up to be <account> For Source I picked “Deploy from a branch”. And for Branch I selected “gh-pages” and “/root”. I also checked the “Enforce HTTPS” option.

Create a Personal Access Token

In order for the JavaScript bookmarklet to function, it need a GitHub Personal Access Token or PAT. This article, Using GitHub Actions with Repository Dispatch Event explains the mechanism used to tie JavaScript and GitHub action together, using a PAT. Creating a personal access token describes how to create and use a PAT.

Add PAT to readingList.js

Once you have created your PAT, you need to add it to line 3 of readingList.js. It becomes the token used by the rest of the code to gain access to your repository.

Update requestURL

You need to update the requestURL value to be the path to your readingList. If you are using GitHub Pages this will look like

Create a Bookmarklet

I used How to create a JavaScript Bookmarklet Easily to compress the JavaScript to a single line. Copy that line and make a bookmark of it in your browser(s).

Using the Bookmarklet

With the bookmarklet created you are ready to put the automation to work. Find an article you’d like to add to your list and click the read bookmark and (if you have all the pieces properly lined up) the page should briefly disappear and reappear. The JavaScript interrogates the page, collecting the URL, the title, the meta data description, etc, and triggers the GitHub Action. It then redirects to the original page. By using the Action this way, the adding of the new entry to your reading list happens asynchronously. You can go to the Actions page of your repository and see the status of the actions as they are running. Within a minute or two the readingList site should be regenerated with the new entry added.

Moving Parts

This automation has many moving parts. Two pieces of JavaScript, GitHub Actions, a GitHub PAT, and GitHub Pages. Getting all the references updated from the original project to your account, getting the path to the repository correct in the readingList.js, making sure that GitHub Pages is setup properly; all these steps are crucial. Tracking down one missing or incorrect piece (the repository path, ahem) can be frustrating.

I had never used GitHub Actions prior to this, and my understanding of JavaScript is rather thin. I spent most of a day reading and learning to make all the parts of this make sense in my head, and making them all work together to have a functional reading list.


I’ve been using this automation for several days now and it works very well. So far there has only been one site where the JavaScript bookmarklet wouldn’t work. I’ve been going through the many open tabs in my browsers and adding articles to my read list.
