'use strict';
var amphtmlValidator = require('amphtml-validator');

amphtmlValidator.getInstance().then(function (validator) {
  var result = validator.validateString('<html>Hello, world.</html>');
  ((result.status === 'PASS') ? console.log : console.error)(result.status);
  for (var ii = 0; ii < result.errors.length; ii++) {
    var error = result.errors[ii];
    var msg = 'line ' + error.line + ', col ' + error.col + ': ' + error.message;
    if (error.specUrl !== null) {
      msg += ' (see ' + error.specUrl + ')';
    }
    ((error.severity === 'ERROR') ? console.error : console.warn)(msg);
  }
});

Now try running it:

$ node demo.js
FAIL
line 1, col 0: The mandatory attribute '⚡' is missing in tag 'html ⚡ for top-level html'. (see https://www.ampproject.org/docs/reference/spec.html#required-markup)
line 1, col 0: The parent tag of tag 'html ⚡ for top-level html' is '$root', but it can only be '!doctype'. (see https://www.ampproject.org/docs/reference/spec.html#required-markup)
...

As expected, this emits errors because the provided string in the example, <html>Hello, world.</html> is not a valid AMP HTML document.

Release Notes

1.0.10

Fixed #4246: amphtml-validator CLI fails on Mac OS X.

1.0.11

Added support for AMP4ADS (via --html_format command line flag) and argument for validateString function in the API.

1.0.12

Added support for --user-agent option.

1.0.13

Added newInstance method, a simple API that's not async.

1.0.15

Added support for installing on Windows. npm install -g amphtml-validator should now just work.

1.0.16

npm install amphtml-validator (local install) should now work on Windows, for require('amphtml-validator').

1.0.17

If the amphtml-validator command is already patched up for Windows, leave it alone instead of failing. Relevant if the package has been installed globally and now we're performing a local install on top of it.

1.0.18

Small tweaks to this file and package.json.

1.0.19

Set correct process exit status for old versions of Node.js (v0.10.25).

1.0.20

Better npm post-install for virtual machines, running debian over windows with SMB shared folder.

1.0.21

--html_format=AMP4ADS is no longer experimental.

1.0.22

--html_format=AMP4EMAIL added.

1.0.23

The amphtml-validator binary now requires the Node.js binary to be called node. On systems where the Node.js binary is called nodejs, consider installing the nodejs-legacy Debian package or better yet, NVM.
