 1 | Want to contribute? Great! First, read this page (including the small print at the end).
 2 | 
 3 | ### Before you contribute
 4 | Before we can use your code, you must sign the
 5 | [Google Individual Contributor License Agreement]
 6 | (https://cla.developers.google.com/about/google-individual)
 7 | (CLA), which you can do online. The CLA is necessary mainly because you own the
 8 | copyright to your changes, even after your contribution becomes part of our
 9 | codebase, so we need your permission to use and distribute your code. We also
10 | need to be sure of various other things—for instance that you'll tell us if you
11 | know that your code infringes on other people's patents. You don't have to sign
12 | the CLA until after you've submitted your code for review and a member has
13 | approved it, but you must do it before we can put your code into our codebase.
14 | Before you start working on a larger contribution, you should get in touch with
15 | us first through the issue tracker with your idea so that we can help out and
16 | possibly guide you. Coordinating up front makes it much easier to avoid
17 | frustration later on.
18 | 
19 | ### Code reviews
20 | All submissions, including submissions by project members, require review. We
21 | use Github pull requests for this purpose.
22 | 
23 | ### The small print
24 | Contributions made by corporations are covered by a different agreement than
25 | the one above, the
26 | [Software Grant and Corporate Contributor License Agreement]
27 | (https://cla.developers.google.com/about/google-corporate).

 92 |       modifications, and in Source or Object form, provided that You
 93 |       meet the following conditions:
 94 | 
 95 |       (a) You must give any other recipients of the Work or
 96 |           Derivative Works a copy of this License; and
 97 | 
 98 |       (b) You must cause any modified files to carry prominent notices
 99 |           stating that You changed the files; and
100 | 
101 |       (c) You must retain, in the Source form of any Derivative Works
102 |           that You distribute, all copyright, patent, trademark, and
103 |           attribution notices from the Source form of the Work,
104 |           excluding those notices that do not pertain to any part of
105 |           the Derivative Works; and
106 | 
107 |       (d) If the Work includes a "NOTICE" text file as part of its
108 |           distribution, then any Derivative Works that You distribute must
109 |           include a readable copy of the attribution notices contained
110 |           within such NOTICE file, excluding those notices that do not
111 |           pertain to any part of the Derivative Works, in at least one
112 |           of the following places: within a NOTICE text file distributed
113 |           as part of the Derivative Works; within the Source form or

119 |           notices within Derivative Works that You distribute, alongside
120 |           or as an addendum to the NOTICE text from the Work, provided
121 |           that such additional attribution notices cannot be construed
122 |           as modifying the License.
123 | 
124 |       You may add Your own copyright statement to Your modifications and
125 |       may provide additional or different license terms and conditions
126 |       for use, reproduction, or distribution of Your modifications, or
127 |       for any such Derivative Works as a whole, provided Your use,
128 |       reproduction, and distribution of the Work otherwise complies with
129 |       the conditions stated in this License.
130 | 
131 |    5. Submission of Contributions. Unless You explicitly state otherwise,
132 |       any Contribution intentionally submitted for inclusion in the Work
133 |       by You to the Licensor shall be under the terms and conditions of
134 |       this License, without any additional terms or conditions.
135 |       Notwithstanding the above, nothing herein shall supersede or modify
136 |       the terms of any separate license agreement you may have executed
137 |       with Licensor regarding such Contributions.
138 | 
139 |    6. Trademarks. This License does not grant permission to use the trade
140 |       names, trademarks, service marks, or product names of the Licensor,

142 |       origin of the Work and reproducing the content of the NOTICE file.
143 | 
144 |    7. Disclaimer of Warranty. Unless required by applicable law or
145 |       agreed to in writing, Licensor provides the Work (and each
146 |       Contributor provides its Contributions) on an "AS IS" BASIS,
147 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148 |       implied, including, without limitation, any warranties or conditions
149 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150 |       PARTICULAR PURPOSE. You are solely responsible for determining the
151 |       appropriateness of using or redistributing the Work and assume any
152 |       risks associated with Your exercise of permissions under this License.
153 | 
154 |    8. Limitation of Liability. In no event and under no legal theory,
155 |       whether in tort (including negligence), contract, or otherwise,
156 |       unless required by applicable law (such as deliberate and grossly
157 |       negligent acts) or agreed to in writing, shall any Contributor be
158 |       liable to You for damages, including any direct, indirect, special,
159 |       incidental, or consequential damages of any character arising as a
160 |       result of this License or out of the use or inability to use the
161 |       Work (including but not limited to damages for loss of goodwill,
162 |       work stoppage, computer failure or malfunction, or any and all
163 |       other commercial damages or losses), even if such Contributor
164 |       has been advised of the possibility of such damages.
165 | 
166 |    9. Accepting Warranty or Additional Liability. While redistributing
167 |       the Work or Derivative Works thereof, You may choose to offer,
168 |       and charge a fee for, acceptance of support, warranty, indemnity,
169 |       or other liability obligations and/or rights consistent with this
170 |       License. However, in accepting such obligations, You may act only
171 |       on Your own behalf and on Your sole responsibility, not on behalf
172 |       of any other Contributor, and only if You agree to indemnify,
173 |       defend, and hold each Contributor harmless for any liability
174 |       incurred by, or claims asserted against, such Contributor by reason
175 |       of your accepting any such warranty or additional liability.
176 | 
177 |    END OF TERMS AND CONDITIONS
178 | 
179 |    APPENDIX: How to apply the Apache License to your work.
180 | 
181 |       To apply the Apache License to your work, attach the following
182 |       boilerplate notice, with the fields enclosed by brackets "{}"

  1 | # amp-prototyper
  2 | 
  3 | This Node.js-based script is a prototyping tool that automatically converts a HTML page to a [Accelerated Mobile Page (AMP)](https://amp.dev) to demonstrate performance gains with AMP. It follows [the general guideline of converting HTML to AMP](https://amp.dev/documentation/guides-and-tutorials/start/converting/).
  4 | 
  5 | ## TL;DR
  6 | 
  7 | - The goal is to showcase the advantages of AMP in page load performance.
  8 | - It generates a converted AMP HTML, a screenshot, and AMP validation errors for each step.
  9 | - It automatically converts a HTML page to AMP with pre-defined steps. You can customize the steps for specific scenarios.
 10 | - Final output contains image comparison and match percentage to original URL. Remove the watermark from the HTML and manually review the output
 11 | 
 12 | ## What is amp-prototyper
 13 | 
 14 | The main goal is to minimize the effort of creating a prototype AMP page from a canonical HTML page, such as adding AMP boilerplate, removing custom Javascript, making all CSS inline, etc. The output of this tool includes converted AMP, the screenshot, and AMP validation errors for each conversion step.
 15 | 
 16 | This script uses [puppeteer](https://github.com/GoogleChrome/puppeteer) to load and render pages.
 17 | 
 18 | ## Non-scope
 19 | 
 20 | This tool doesn't aim to create production-ready AMP pages from any arbitrary HTML pages. If your goal is to create high-quality AMP pages for production, please follow [the general guideline of converting HTML to AMP](https://amp.dev/documentation/guides-and-tutorials/start/converting/).
 21 | 
 22 | ## Getting started
 23 | 
 24 | To run the script, you may choose one of the following methods:
 25 | 
 26 | #### npx
 27 | 
 28 | Run the script directly with npx:
 29 | 
 30 | ```
 31 | npx amp-prototyper [URL]
 32 | ```
 33 | 
 34 | - `URL` - URL to the page to convert.
 35 | 
 36 | #### npm or yarn
 37 | 
 38 | Install amp-prototyper package.
 39 | 
 40 | ```
 41 | git clone https://github.com/jonchenn/amp-prototyper.git
 42 | cd amp-prototyper
 43 | yarn install
 44 | ```
 45 | 
 46 | Then, run the script.
 47 | ```
 48 | ./amp-prototyper [URL]
 49 | ```
 50 | 
 51 | ### Usage
 52 | 
 53 | ```
 54 | ./amp-prototyper [URL]
 55 | ```
 56 | 
 57 | Required arguments:
 58 | 
 59 | - `URL` - URL to the page to convert.
 60 | 
 61 | ### Options
 62 | 
 63 | - `--steps=FILE` - Path to the custom steps JS file. If not defined, it will use ./steps/default-steps.js
 64 | - `--output=FILE` - Path to the output file.
 65 | - `--device=DEVICE_NAME` - Use specific device name for screenshots.
 66 | - `--headless=(true|false)` - Whether to show browser.
 67 | - `--fullPageScreenshot=(true|false*)` - tWhether to save full-page screenshots.
 68 | - `--compareScreenshots=(true|false*)` - Whether to compare original site with converted.
 69 | - `--customHost=HOST` - Use a custom host name when updating relative asset URLs.
 70 | - `--port=PORT_NUMBER` - Port number to use to compare before and after (defaults to 8080)
 71 | - `--verbose` - Display AMP validation errors.
 72 | 
 73 | ### Examples:
 74 | 
 75 | ```
 76 | # Amplify a page and generate results in /output folder.
 77 | ./amp-prototyper https://thinkwithgoogle.com
 78 | 
 79 | # Amplify a page and generate results in /output/test folder.
 80 | ./amp-prototyper https://thinkwithgoogle.com --output=test
 81 | 
 82 | # Amplify a page with customized steps.
 83 | ./amp-prototyper https://thinkwithgoogle.com --steps=custom/mysteps.js
 84 | 
 85 | # Amplify a page and display AMP validation details.
 86 | ./amp-prototyper https://thinkwithgoogle.com --verbose
 87 | 
 88 | # Amplify a page and generate screenshots with specific Device.
 89 | ./amp-prototyper https://thinkwithgoogle.com --device='Pixel 2'
 90 | 
 91 | # Amplify a page and display browser.
 92 | ./amp-prototyper https://thinkwithgoogle.com --headless=false
 93 | 
 94 | # Amplify a page and compare original site with converted.
 95 | ./amp-prototyper https://thinkwithgoogle.com --compareScreenshots=true
 96 | 
 97 | # Amplify a page that served from localhost and generate results with correct absolute URLs for assets.
 98 | ./amp-prototyper https://thinkwithgoogle.com --customHost=https://example.com
 99 | ```
100 | 
101 | ### Test with a sample HTML.
102 | 
103 | You can also run a sample HTML with following:
104 | 
105 | ```
106 | # Run a localhost web server using http-server.
107 | yarn sample
108 | ```
109 | 
110 | This opens up a localhost web server at <http://127.0.0.1:8080> by default that serves [test/index.html](https://github.com/jonchenn/amp-prototyper/blob/master/test/index.html). This is a quick and simple HTML page to test amp-prototyper. You can run the following to see how amp-prototyper works. (If localhost has trouble connecting to the port, add the --port flag with a different port number)
111 | 
112 | ```
113 | # Amplify the page at localhost and output in sample/ folder.
114 | ./amp-prototyper http://127.0.0.1:8080 --output=sample
115 | ```
116 | 
117 | Then, check out the `./output/sample`, and you will see a list of output files.
118 | 
119 | ## Output of each step
120 | 
121 | When you run the script, it follows predefined steps, either default steps at [src/default-steps.js](https://github.com/jonchenn/amp-prototyper/blob/master/src/default-steps.js), or customized steps.
122 | 
123 | You can amplify a HTML page with default steps:
124 | 
125 | ```
126 | # Amplify a page with default steps.
127 | ./amp-prototyper http://127.0.0.1:8080
128 | ```
129 | 
130 | Or run amplify a page with customized steps:
131 | 
132 | ```
133 | # Amplify a page with customized steps.
134 | ./amp-prototyper http://127.0.0.1:8080 --steps=custom/mysteps.js
135 | ```
136 | 
137 | At each step, it executes a set of actions and writes the files below to the output/ folder:
138 | 
139 | - `output-step-[STEP_ID].html` - the modified HTML.
140 | - `output-step-[STEP_ID].png` - the screenshot after this step.
141 | - `output-step-[STEP_ID]-validation.txt` (only with --verbose) - AMP validation errors from console output.
142 | 
143 | If you don't specify --output, it uses the domain from the given URL as the name of the output folder.
144 | 
145 | ### Verify your output
146 | 
147 | You can run the following command to run a simple web server locally to serve your output files.
148 | 
149 | ```
150 | yarn output
151 | ```
152 | 
153 | Open up the localhost URL with a browser. For example: <http://127.0.0.1:8080>
154 | 
155 | Check the image comparsion to see visual differences in the original URL and AMP HTML
156 | 
157 | Remove the watermark in the AMP HTML and review the code for additional changes/AMP validation error fixes
158 | 
159 | ### Caveats
160 | 
161 | - Styles from '@import' media queries must be manually added
162 | - HTML containing ShadowDOMs and nested ShadowDOMS are unsupported
163 | 
164 | ## Customize steps
165 | 
166 | ### Structure of steps
167 | 
168 | You can check out the default steps at [src/default-steps.js](https://github.com/jonchenn/amp-prototyper/blob/master/src/default-steps.js).
169 | 
170 | Each step follows the structure below.
171 | 
172 | ```
173 | {
174 |   name: 'Name of the step',
175 |   actions: [{
176 |     skip: false,
177 |     log: 'Log output for this action',
178 |     actionType: 'replace',
179 |     selector: 'html',
180 |     regex: '<div(.*)>(.*)</div>',
181 |     replace: '<span$1>$2</span>',
182 |   }, {
183 |     ...
184 |   }],
185 | },
186 | ```
187 | 
188 | Step properties:
189 | 
190 | - `name` <[string]> Step name.
191 | - `actions` <[Array]<[Action]()>> actions to execute.
192 | - `skip` <[boolean]> Whether to skip this step.
193 | 
194 | Common properties of an action:
195 | 
196 | - `actionType` <string]> Action type.
197 | - `log` <[string]> Message output of this action.
198 | - `waitAfterLoaded` <[number]> Wait for a specific milliseconds after the page loaded.
199 | 
200 | ### Environment Variables
201 | 
202 | You can also use the following EnvVars in the steps configuration.
203 | 
204 | - `$URL` <[string]> The URL from the `--url` parameter.
205 | - `$HOST` <[string]> The host derived from the URL.
206 | - `$DOMAIN` <[string]> The domain derived from the URL.
207 | 
208 | For example, you have a step like below:
209 | 
210 | ```
211 | {
212 |   name: 'Name of the step',
213 |   actions: [{
214 |     log: 'Log output for this action',
215 |     actionType: 'replace',
216 |     selector: 'html',
217 |     regex: '<div(.*)>(.*)</div>',
218 |     replace: '<span$1>$HOST</span>',
219 |   }],
220 | },
221 | ```
222 | 
223 | While running the script with `https://example.com`, it replaces """$HOST""" with "<https://example.com">.
224 | 
225 | ### Supported actions:
226 | 
227 | #### setAttribute
228 | 
229 | Set an attribute to a specific element.
230 | 
231 | - `selector` <[string]> target element.
232 | - `attribute` <[string]> attribute to ad.
233 | - `value` <[string]> the attribute value.
234 | 
235 | #### removeAttribute
236 | 
237 | Remove an attribute to a specific element.
238 | 
239 | - `selector` <[string]> target element.
240 | - `attribute` <[string]> attribute to remove.
241 | #### replace
242 | 
243 | Use Regex to find and replace in the DOM.
244 | 
245 | - `selector` <[string]> target element.
246 | - `regex` <[string]> Regex string to match.
247 | - `replace` <[string]> Replace matches with this string.
248 | #### removeDisallowedAttribute
249 | 
250 | Remove an attribute to specific elements based on AMP validation errors.
251 | 
252 | - `selector` <[string]> target element.
253 | #### replaceBasedOnAmpErrors
254 | 
255 | Use Regex to find and replace in the DOM based on AMP validation errors.
256 | 
257 | - `selector` <[string]> target element.
258 | - `ampErrorRegex` <[string]> Regex string to match for AMP validation errors.
259 | - `regex` <[string]> Regex string to match.
260 | - `replace` <[string]> Replace matches with this string.
261 | For example, in a specific step it has the following AMP validation errors.
262 | 
263 | ```
264 | line 61, col 4: The attribute 'onclick' may not appear in tag 'button'.
265 | line 70, col 4: The tag 'custom-tag' is disallowed.
266 | ```
267 | 
268 | To replace the
269 | 
270 | <custom-tag> in the body based on the AMP validation result, you
271 | can have the following step:</custom-tag>
272 | 
273 | ```
274 | {
275 |   name: 'Convert disallowed tags to <div> based on AMP validation result.',
276 |   actions: [{
277 |     log: 'Change tags to <div>',
278 |     actionType: 'replaceBasedOnAmpErrors',
279 |     selector: 'body',
280 |     ampErrorRegex: 'The tag \'([^\']*)\' is disallowed',
281 |     regex: '<($1)((.|[\\r\\n])*)</$1>',
282 |     replace: '<div data-original-tag="$1" $2</div>',
283 |   }],
284 | }
285 | ```
286 | 
287 | This step matches the AMP validation result with `ampErrorRegex`. Then it replace the `regex` with the capturing group #1 from `ampErrorRegex`. In this case, the `regex` becomes:
288 | 
289 | ```
290 | <(custom-tag)((.|[\\r\\n])*)</custom-tag>
291 | ```
292 | 
293 | Finally, it uses the revised `regex` to replace the content with `replace` value.
294 | 
295 | #### replaceOrInsert
296 | 
297 | Use Regex to find and replace in the DOM. If not found, insert to the destination element.
298 | 
299 | - `selector` <[string]> target element.
300 | - `regex` <[string]> Regex string to match.
301 | - `replace` <[string]> Replace matches with this string.
302 | #### insert
303 | 
304 | Insert a string to the bottom of the destination element. E.g. adding a string to the bottom of the .
305 | 
306 | - `selector` <[string]> target element.
307 | - `value` <[string]> the string to insert.
308 | - `destSelector` <[string]> destination element.
309 | #### move
310 | 
311 | Move elements to the bottom of the destination element. E.g. moving all
312 | 
313 | <link>
314 | 
315 |  to the bottom of the .
316 | 
317 | - `selector` <[string]> target element.
318 | - `destSelector` <[string]> destination element.
319 | #### appendAfter
320 | 
321 | Append a string right after a specific element.
322 | 
323 | - `selector` <[string]> target element.
324 | - `value` <[string]> the string to append.
325 | #### inlineExternalStyles
326 | 
327 | Collect all external CSS and append a `<style>` tag with inline CSS.
328 | 
329 | - `selector` <[string]> target element to append the CSS.
330 | - `value` <[string]> the string to append.
331 | - `excludeDomains` <[Array]<[string]>> the array of excluded domains. E.g. [&#39;examples.com&#39;] excludes all CSS loaded from <code>examples.com</code>.
332 | - `minify` <[boolean]> whether to minify CSS.
333 | - `attributes` <[Array]<[string]>> add attributes when appending `<style>` tag.
334 | 
335 | #### removeUnusedStyles
336 | 
337 | Remove unused CSS using [clean-css](https://github.com/jakubpawlowicz/clean-css) and [purifycss](https://github.com/purifycss/purifycss).
338 | 
339 | - `selector` <[string]> target element.
340 | - `value` <[string]> the string to append.
341 | 
342 | #### customFunc
343 | 
344 | Run the action with a custom function. Example:
345 | 
346 | An action object:
347 | ```
348 |   {
349 |     log: &#39;Click a button&#39;,
350 |     actionType: &#39;customFunc&#39;,
351 |     customFunc: async (action, sourceDom, page) =&gt; {
352 |       await page.click(&#39;button#summit&#39;);
353 |     },
354 |   }],
355 | },
356 | ```
357 | 
358 | In the custom function, there are three arguments:
359 | 
360 | - `action` <[ActionObject]> the action object itself.
361 | - `sourceDom` <[DOM document]> the raw DOM document object before rendering, as in the View Source in Chrome.
362 | - `page` <[puppeteer Page object]> The page object in puppeteer.
363 | 
364 | ### Customize steps
365 | 
366 | To customize your own steps for specific scenarios, create a .js file like below:
367 | 
368 | ```
369 | module.exports = [
370 |   {
371 |     name: &#39;Remove unwanted styles&#39;,
372 |     actions: [{
373 |       log: &#39;Remove inline styles in body&#39;,
374 |       actionType: &#39;replace&#39;,
375 |       selector: &#39;body&#39;,
376 |       regex: &#39;(&lt;!--)?.*&lt;style[^&lt;]*(?:(?!&lt;\/style&gt;)&lt;[^&lt;]*)*&lt;\/style&gt;.*(--&gt;)?&#39;,
377 |       replace: &#39;&#39;,
378 |     }, {
379 |       log: &#39;Remove noscript in body&#39;,
380 |       actionType: &#39;replace&#39;,
381 |       selector: &#39;body&#39;,
382 |       regex: &#39;(&lt;!--)?.*&lt;noscript[^&lt;]*(?:(?!&lt;\/noscript&gt;)&lt;[^&lt;]*)*&lt;\/noscript&gt;.*(--&gt;)?&#39;,
383 |       replace: &#39;&#39;,
384 |     }],
385 |   }, {
386 |     ...
387 |   }
388 | ];
389 | ```
390 | 
391 | Next, run the script with `--steps=/path/to/mysteps.js`
392 | 
393 | ```
394 | # Amplify a page with customized steps.
395 | ./amp-prototyper http://127.0.0.1:8080 --steps=/path/to/mysteps.js
396 | ```
397 | 
398 | ## Use cases with specific conditions
399 | 
400 | ### Sites with Crawler Protection
401 | 
402 | Since AMP-prototyper is built with [Puppeteer](https://github.com/GoogleChrome/puppeteer) to fetch a page content, some sites may treat this as a crawler or bot, and thus block the access. You may see a different content (e.g. 404 page or timeout) than the regular page content.
403 | 
404 | The blocking logic usually resides in the web hosting servers. Hence, there's no easy way to overcome. However, you can try the following options:
405 | 
406 | #### Option 1 - Set headless=false
407 | 
408 | Some sites may treat puppeteer activities as crawler if it runs in the headless mode. You can try running with headless off, and puppeteer will show the browser window like browsing by a real user.
409 | 
410 | ```
411 | # Amplify a page without headless mode.
412 | ./amp-prototyper http://127.0.0.1:8080 --headless=false
413 | ```
414 | 
415 | #### Option 2 - Serve the page locally
416 | 
417 | Another option to bypass crawler-protection is to download the page and serve the page from a local web server. (E.g. [http-server](https://www.npmjs.com/package/http-server))
418 | 
419 | For example, you can save the index page of [ThinkWithGoogle.com](https://www.thinkwithgoogle.com) and serve it locally.  It's recommended to copy the **page source** directly instead of using a browser's Save function to avoid unexpected artifacts by the browser.
420 | 
421 | Since the host is now `localhost` instead of its original host (www.thinkwithgoogle.com), all relative asset paths would incorrectly end up with localhost. Hence, we need to pass `--customHost` to restore its true remote host for asset URLs.
422 | 
423 | ```
424 | # Assuming that the index page is saved to ./tmp/web/index.html
425 | 
426 | npm i http-server -g
427 | http-server ./tmp/web -p 3000
428 | ```
429 | 
430 | In a new terminal:
431 | 
432 | ```
433 | ./amp-prototyper http://127.0.0.1:3000 --customHost=https://www.thinkwithgoogle.com
434 | ```
