The full data behind [Can I use][1] is incredibly useful for any front end developer, and on the website all of the details from the database are displayed to the user. However in automated tools, [many of these fields go unused][2]; it's not a problem for server side consumption but client side, the less JavaScript that we send to the end user the better. caniuse-lite then, is a smaller dataset that keeps essential parts of the data in a compact format. It does this in multiple ways, such as converting `null` array entries into empty strings, representing support data as an integer rather than a string, and using base62 references instead of longer human-readable keys. This packed data is then reassembled (via functions exposed by this module) into a larger format which is mostly compatible with caniuse-db, and so it can be used as an almost drop-in replacement for caniuse-db for contexts where size on disk is important; for example, usage in web browsers. The API differences are very small and are detailed in the section below. ## API ```js import * as lite from 'caniuse-lite'; ``` ### `lite.agents` caniuse-db provides a full `data.json` file which contains all of the features data. Instead of this large file, caniuse-lite provides this data subset instead, which has the `browser`, `prefix`, `prefix_exceptions`, `usage_global` and `versions` keys from the original. In addition, the subset contains the `release_date` key with release dates (as timestamps) for each version: ```json { "release_date": { "6": 998870400, "7": 1161129600, "8": 1237420800, "9": 1300060800, "10": 1346716800, "11": 1381968000, "5.5": 962323200 } } ``` ### `lite.feature(js)` The `feature` method takes a file from `data/features` and converts it into something that more closely represents the `caniuse-db` format. Note that only the `title`, `stats` and `status` keys are kept from the original data. ### `lite.features` The `features` index is provided as a way to query all of the features that are listed in the `caniuse-db` dataset. Note that you will need to use the `feature` method on values from this index to get a human-readable format. ### `lite.region(js)` The `region` method takes a file from `data/regions` and converts it into something that more closely represents the `caniuse-db` format. Note that *only* the usage data is exposed here (the `data` key in the original files). ## License The data in this repo is available for use under a CC BY 4.0 license (http://creativecommons.org/licenses/by/4.0/).
