ecoindex_cli 2.23.0

`ecoindex-cli` is a CLI tool that let you make ecoindex tests on given pages

Ecoindex-Cli

This tool provides an easy way to analyze websites with Ecoindex from your local computer using multi-threading. You have the ability to:

• Make the analysis on multiple pages
• Define multiple screen resolution
• Make a recursive analysis from a given website

This CLI is built on top of ecoindex-python with Typer

The output is a CSV or JSON file with the results of the analysis.

Requirements

• Docker

Quickstart

The simplest way to start with ecoindex-cli is to install docker and then create an alias in your .bashrc or .zshrc file:

alias ecoindex-cli="docker run -it --rm -v /tmp/ecoindex-cli:/tmp/ecoindex-cli vvatelot/ecoindex-cli:latest ecoindex-cli"

Then you can use the cli as if it was installed on your computer:

ecoindex-cli --help

Use case

The docker image vvatelot/ecoindex-cli is available for linux/amd64 and linux/arm64 platforms and provides you an easy way to use this CLI on your environment.

The one line command to use it is:

ecoindex-cli analyze --url https://www.ecoindex.fr --recursive --html-report 

Make a simple analysis

You give just one web url

ecoindex-cli analyze --url https://www.ecoindex.fr

This makes an analysis with a screen resolution of 1920x1080px by default and with the last known version of chromedriver. You can set those settings with options: --window-size and --chrome-version You can add multiple urls to analyze with the option --url. For example:

ecoindex-cli analyze --url https://www.ecoindex.fr --url https://www.ecoindex.fr/a-propos/

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

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 https://www.ecoindex.fr --recursive

Result

You are about to perform a recursive website scraping. This can take a long time. Are you sure to want to proceed? [Y/n]:

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 https://www.ecoindex.fr --recursive --html-report

🦄️ Amazing! A report has been generated to /tmp/ecoindex-cli/output/www.ecoindex.fr/2023-14-04_141645/index.html

When generating a html report, the results are written in a CSV file and you can not specify the result file location. So options --export-format and --output-file are ignored.

Here is a sample result:

Other features

Set the output file

You can define the csv output file

ecoindex-cli analyze --url https://www.ecoindex.fr --output-file ~/ecoindex-results/ecoindex.csv

Export to JSON file

By default, the results are exported to a CSV file. But, you can specify to export the results to a JSON file.

ecoindex-cli analyze --url https://www.ecoindex.fr --export-format json

Change wait before / after scroll

By default, the scenario waits 3 seconds before and after scrolling to bottom of the page so that the analysis results are conform to the Ecoindex main API methodology.

You can change this value with the option --wait-before-scroll and --wait-after-scroll to fit your needs.

ecoindex-cli analyze --url https://www.ecoindex.fr --wait-before-scroll 1 --wait-after-scroll 1

Using a specific Chrome version

You can use a specific Chrome version to make the analysis. This is useful if you use an old chrome version. You just have to provide the main Chrome version number.

ecoindex-cli analyze --url https://www.ecoindex.fr --chrome-version 107

Or if you do not know the Chrome version number, you can use the one line command

ecoindex-cli analyze --url https://www.ecoindex.fr --chrome-version (google-chrome --version  | grep --only -P '(?<=\\s)\\d{3}')

Using multi-threading

You can use multi-threading to speed up the analysis when you have a lot of websites to analyze. In this case, you can define the maximum number of workers to use:

ecoindex-cli analyze --url https://www.ecoindex.fr --url https://www.greenit.fr/ --max-workers 10

By default, the number of maximum workers is set to CPU count.

Disable console interaction

You can disable confirmations, and force the app to answer yes to all of them. It can be useful if you need to start the app from another script, or if you have no time to wait it to finish.

ecoindex-cli analyze --url https://www.ecoindex.fr --recursive --no-interaction

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 "/tmp/ecoindex-cli/output/www.ecoindex.fr/2021-05-06_191355/results.csv" "www.synchrone.fr"

Result

🦄️ Amazing! A report has been generated to /tmp/ecoindex-cli/output/www.ecoindex.fr/2021-05-06_191355/index.html

Results example

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

Development

Requirements

• Python 3.10+
• Poetry
• Chrome (or Chromium)

Installation

At first, you need to install dependencies:

git clone
cd ecoindex-cli
poetry install

You also need to install Google Chrome or Chromium and the corresponding ChromeDriver for your OS.

You have to download the chrome driver and put it in the project path. You can also use the --chromedriver-path option to specify the path to the chrome driver.

Usage

poetry run ecoindex-cli --help
poetry run ecoindex-cli analyze --help
poetry run ecoindex-cli report --help

Testing

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

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

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