Make a simple analysis

You give just one web url

➜ ecoindex-cli analyze --url http://www.ecoindex.fr
There are 1 url(s), do you want to process? [Y/n]:
1 urls for 1 window size
Processing  [####################################]  100%
🙌️ File output/www.ecoindex.fr/2021-04-20 16:44:33.468755/results.csv written !

This makes an analysis with a screen resolution of 1920x1080px by default

Set the output file

You can define the csv output file

➜ ecoindex-cli analyze --url http://www.ecoindex.fr --output-file ~/ecoindex-results/ecoindex.csv
📁️ Urls recorded in file `input/www.ecoindex.fr.csv`
There are 1 url(s), do you want to process? [Y/n]: 
1 urls for 1 window size
Processing  [####################################]  100%
🙌️ File /home/vvatelot/ecoindex-results/ecoindex.csv written !

Multiple url analysis

➜ ecoindex-cli analyze --url http://www.ecoindex.fr --url https://www.greenit.fr/
There are 2 url(s), do you want to process? [Y/n]:
2 urls for 1 window size
Processing  [####################################]  100%
🙌️ File output/www.ecoindex.fr/2021-04-20 16:45:24.458052/results.csv written !

Provide urls from a file

You can use a file with given urls that you want to analyze: One url per line. This is helpful if you want to play the same scenario recurrently.

➜ ecoindex-cli analyze --urls-file input/ecoindex.csv
There are 2 url(s), do you want to process? [Y/n]:
2 urls for 1 window size
Processing  [####################################]  100%
🙌️ File output/www.ecoindex.fr/2021-04-20 16:45:24.458052/results.csv written !

Make a recursive analysis

You can make a recursive analysis of a given webiste. This means that the app will try to find out all the pages into your website and launch an analysis on all those web pages. ⚠️ This can process for a very long time! Use it at your own risks!

➜ ecoindex-cli analyze --url http://www.ecoindex.fr --recursive
⏲️ Crawling root url http://www.ecoindex.fr -> Wait a minute !
📁️ Urls recorded in file `input/www.ecoindex.fr.csv`
There are 3 url(s), do you want to process? [Y/n]:
3 urls for 1 window size
Processing  [####################################]  100%
🙌️ File output/www.ecoindex.fr/2021-04-20 16:47:29.072472/results.csv written !

Set other screen resolutions

You can provide other screen resolutions. By default, the screen resolution is 1920x1080px but you can provide other resolution for example if you want to test ecoindex for mobile.

➜ ecoindex-cli analyze --url http://www.ecoindex.fr --window-size 1920,1080 --window-size 386,540
There are 1 url(s), do you want to process? [Y/n]:
1 urls for 2 window size
Processing  [####################################]  100%
🙌️ File output/www.ecoindex.fr/2021-04-21 21:22:44.309077/results.csv written !

Generate a html report

You can generate a html report easily at the end of the analysis. You just have to add the option --html-report.

➜ ecoindex-cli analyze --url http://www.ecoindex.fr --recursive --html-report
⏲️ Crawling root url http://www.ecoindex.fr -> Wait a minute !
📁️ Urls recorded in file `input/www.ecoindex.fr.csv`
There are 3 url(s), do you want to process? [Y/n]:
3 urls for 1 window size
Processing  [####################################]  100%
🙌️ File output/www.ecoindex.fr/2021-04-21 21:21:27.629691/results.csv written !
🦄️ Amazing! A report has been generated to `/home/vvatelot/Devel/ecoindex_cli/output/www.ecoindex.fr/2021-04-21 21:21:27.629691/report.html`

Here is a sample result:

Only generate a report from existing result file

If you already performed an anlayzis and (for example), forgot to generate the html report, you do not need to re-run a full analyzis, you can simply request a report from your result file :

➜ ecoindex-cli report "/home/vvatelot/Devel/ecoindex_cli/output/www.ecoindex.fr/2021-05-06 19:13:55.735935/results.csv" "www.synchrone.fr"
🦄️ Amazing! A report has been generated to `/home/vvatelot/Devel/ecoindex_cli/output/www.ecoindex.fr/2021-05-06 19:13:55.735935/report.html`

Results example

The result of the analysis is a CSV file which can be easily used for further analysis:

size,nodes,requests,grade,score,ges,water,url,date,resolution,page_type
119.095,45,8,A,89,1.22,1.83,http://www.ecoindex.fr,2021-04-20 16:45:28.570179,"1920,1080",

Where:

• size is the size of the page and of the downloaded elements of the page in KB
• nodes is the number of the DOM elements in the page
• requests is the number of external requests made by the page
• grade is the corresponding ecoindex grade of the page (from A to G)
• score is the corresponding ecoindex score of the page (0 to 100)
• ges is the equivalent of greenhouse gases emission (in gCO2e) of the page
• wateris the equivalent water consumption (in cl) of the page
• url is the analysed page url
• date is the datetime of the page analysis
• resolution is the screen resolution used for the page analysis (width,height)
• page_type is the type of the page, based ton the opengraph type tag

Testing

We use Pytest to run unit tests for this project. The test suite are in the tests folder. Just execute :

pytest --cov-report term-missing:skip-covered --cov=. --cov-config=.coveragerc tests

This runs pytest and also generate a coverage report (terminal and html)
