15 | ## How to use
16 | 
17 | In the root directory of your project run:
18 | 
19 | ```yaml
20 | npx browserslist-ga
21 | ```
22 | 
23 | _([npx](https://medium.com/@maybekatz/introducing-npx-an-npm-package-runner-55f7d4bd282b) comes with npm 5.2+, for older versions run `npm install -g browserslist-ga` and then `browserslist-ga`)_  
24 | _(to run the latest code directly from GitHub, execute `npx github:browserslist/browserslist-ga` instead)_
25 | 
26 | You'll be asked to login with your Google Account (please see [this issue](https://github.com/browserslist/browserslist-ga/issues/26#issuecomment-568583144) if you are unable to sign in). Your access token will only be used locally to generate a `browserslist-stats.json` file in the root of your project. After finishing the steps, you can use your stats with Browserlist by adding the following to your [Browserslist config](https://github.com/ai/browserslist#config-file):
27 | 
28 | ```yaml
29 | > 0.5% in my stats  # Or a different percentage
30 | ```
31 | 
32 | Note that you can query against your custom usage data while also querying against global or regional data. For example, the query `> 1% in my stats, > 5% in US, 10%` is permitted.
33 | 
34 | ## Why should I care?
35 | 
36 | Browsers update very often these days, with major releases getting published every month.
37 | With each new browser version comes support for new web platform features.
38 | Thanks to open source projects such as Autoprefixer and Babel we are able to use these features while supporting older browsers.
39 | But this backward compatibility comes with a cost.
40 | We can't really keep adding prefixes, polyfills and other fallbacks to support every browser ever invented.
41 | 
42 | Browserslist is an open source project that can minimize those costs by allowing you to configure which browsers you care about.
43 | It is supported by tools such as
44 | [Autoprefixer](https://github.com/postcss/autoprefixer),
45 | [babel-preset-env](https://github.com/babel/babel/tree/master/packages/babel-preset-env),
46 | [postcss-normalize](https://github.com/jonathantneal/postcss-normalize) and many others.
47 | Here's how you configure Browserslist:
48 | 
49 | ```yaml
50 | > 1%              # I want to support browser versions that have more than 1% of global usage
51 | Last 2 versions   # And the latest 2 versions of each browser
52 | IE 9              # And also Internet Explorer 9 specifically
53 | ```
54 | 
55 | The global browser usage data comes from [caniuse.com](https://caniuse.com) and is downloaded from npm when you run `npm install`.
56 | Package managers such as npm and Yarn will generate a lockfile with the exact version of each package that was installed.
57 | This means the caniuse database that is used to perform these queries will always be the same.
58 | This is great because it's predictable, but it's important to update this package from time to time to keep up with the latest stats.
59 | Apart from remembering to update this package, there's something else you should consider:
60 | 
61 | * For instance, in China there are some popular browsers that are not used in the US and Europe.
62 | * Or maybe your audience uses mostly mobile browsers.
63 | * Or maybe you are building an application for the government and need to support Internet Explorer 8.
64 | 
65 | The point being, it's important to make decisions based on your audience.
66 | Browserslist-GA aims to help you with that.
67 | It integrates Google Analytics with Browserslist to keep your targeted browsers updated.
68 | 
69 | ## Notes
70 | 
71 | There are some differences compared to the `caniuse` Google Analytics importer:
72 | 
73 | * All browsers on iOS use Safari's WebKit as the underlying engine, and hence will be resolved to Safari. The  `caniuse` Google Analytics parser only converts some of the data to Safari, while the remaining is left untracked (see [#1](https://github.com/browserslist/browserslist-ga/pull/1)).
74 | * YaBrowser, a popular browser in russian-speaking countries, uses the Blink web browser engine and is based on Chromium. It is currently not available on `caniuse` and so is resolved to Chrome (or Chrome for Android) and the version is mapped to the nearest available version (see [#2](https://github.com/browserslist/browserslist-ga/pull/2)).
75 | * Just like for YaBrowser, the [same approach](https://github.com/dmfrancisco/map-to-chrome/blob/master/data/coc_coc_browser.json) is applied to the Coc Coc browser.
76 | 
77 | ## Kudos
78 | 
79 | All the praise goes to the humans and martians that develop and maintain [Can I Use](https://caniuse.com) and [Browserslist](https://github.com/ai/browserslist).
