Question 1

How accurate is Readability for extracting publication dates?

Accepted Answer

Accuracy varies by webpage structure, as it relies on parsing algorithms. For reliable results, test with target sites and consider using the configurable options to adjust extraction logic.

Question 2

Does Readability handle JavaScript-heavy sites like React apps?

Accepted Answer

No, it processes raw HTML only, so content loaded dynamically via JavaScript won't be extracted. You need to pre-render the HTML using tools like headless browsers before using Readability.

Question 3

How to improve Readability's extraction for specific websites?

Accepted Answer

Adjust the options in the summarize function, such as setting clean_conditionally: false or modifying min_text_length. Refer to the readability.ex file for more algorithm and regex customization.

Question 4

Readability vs Mozilla's readability.js – which is better for my project?

Accepted Answer

Choose Readability if you're working in Elixir and need a native library with configurable options. Use readability.js for JavaScript/Node.js environments or if you prioritize browser integration, as it's the original Firefox implementation.

Question 5

Is Readability production-ready for large-scale content aggregation?

Accepted Answer

Yes, with good test coverage and CI, it's stable, but be prepared to handle edge cases with configuration and possibly supplement it with other tools for path conversion or JavaScript rendering.

Question 6

How to extract images along with text using Readability?

Accepted Answer

Readability doesn't have built-in image extraction, but you can use Floki, as shown in the examples, to parse image URLs from the article HTML after extraction. This requires additional dependencies and code.
