Package Exports
- caniuse-lite
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (caniuse-lite) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
caniuse-lite
A smaller version of caniuse-db, with only the essentials!
Why?
The full data behind Can I use 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; 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 the essential parts of the
original, and then packs those parts down on disk. So for example, the original
database stores support for a feature as a string, e.g. "y", whereas
caniuse-lite uses integers. These integers are then converted back to strings
by using the appropriate conversion methods exposed by this module.
API
import * as lite from 'caniuse-lite';lite.agents
caniuse-db provides the agents key in the full data.json, which includes
all of the data. caniuse-lite provides this data instead, which has the
usage_global, prefix and prefix_exceptions keys from the original. Note
that the versions key is also included, but unlike caniuse-db, there are no
null values included with this data.
lite.feature(json)
The feature method takes a file from data/features-json and converts it
into something that more closely represents the caniuse-db format. Note that
only the 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. You should probably pair this index
with the feature method to get something more human-readable.
lite.region(json)
The region method takes a file from data/region-usage-json 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),
with any null values removed.
