Axios v1.1.0 Broken Update Causes "TypeError: axios.get is not a function" Errors

Axios is a Promise‑based HTTP client library for browsers and Node.js, known for its small size and easy‑to‑extend API.

In the recently released 1.1.0 version, a corrupted build caused thousands of websites to break, with users encountering a TypeError: axios.get is not a function error.

According to reported issues, calling axios.get in the broken version triggers the error, preventing virtually all HTTP requests from succeeding.

One reproducible example involves adding the faulty library via a script tag and then invoking axios.get():

<script src="https://unpkg.com/[email protected]/dist/axios.min.js"></script>
<script>
    axios.get(...)
</script>

Note that the problem does not occur in version 1.0.0.

Developers reported production crashes, with many finding that rolling back to 1.0.0 resolves the issue, though app review processes can delay the fix.

Some criticized the practice of automatically pulling the latest CDN version, calling it a foolish approach.

The Axios team responded by releasing two quick patches, versions 1.1.1 and 1.1.2, and recommend that all users upgrade to the latest release.
