Question 1

How do I set up ESL in a web project?

Accepted Answer

Include the ESL script via CDN or local file, then configure module paths and dependencies using the config options detailed in the documentation. Start by defining modules with define() and loading them with require() for AMD compliance.

Question 2

ESL vs RequireJS: which is better for my app?

Accepted Answer

ESL is better for browser-only projects prioritizing size and performance, as it's smaller and faster per the README's comparisons. RequireJS offers broader compatibility with non-browser environments and more features, but with a larger footprint.

Question 3

Does ESL support ES6 import/export syntax?

Accepted Answer

No, ESL is based on the AMD specification and does not natively support ES6 modules. You would need to transpile ES6 code to AMD format using tools like Babel or rely on AMD-compatible builds.

Question 4

Can ESL be used with modern bundlers like Webpack?

Accepted Answer

ESL is a runtime loader, so it's typically used independently for AMD modules. While it can be integrated in build processes, it's not designed to replace bundlers like Webpack, which handle ES modules and other formats more seamlessly.

Question 5

How does lazy loading work in ESL?

Accepted Answer

ESL supports lazy define through configuration options, allowing modules to be defined only when required. This defers loading of non-essential modules, improving initial page load times as mentioned in the README.

Question 6

What are common errors in ESL and how to debug them?

Accepted Answer

Common errors include missing dependencies or configuration issues. ESL provides clear error messages, and the README links to detailed error documentation that explains scenarios like module load failures and resolution steps.
