Include react-geo dependency
react-geo
is published at https://www.npmjs.com/package/@terrestris/react-geo and
can be integrated and installed in your my-app application via
basic npm
commands.
Add react-geo dependency
To add the dependency react-geo
please navigate to your project's folder
(if not already done) and execute:
npm i @terrestris/react-geo
This will add the latest version of react-geo
to your local package.json
file
(into the dependencies
section) and download the distributed version of the
library to the node_modules
directory.
Add Ant Design und OpenLayers dependencies
You may have noticed that the step from above has produced some warnings, which
include react-geo
:
npm WARN @terrestris/react-geo@16.2.2 requires a peer of antd@~3.0 but none is installed. You must install peer dependencies yourself. npm WARN @terrestris/react-geo@16.2.2 requires a peer of ol@~5.0 but none is installed. You must install peer dependencies yourself. npm WARN @terrestris/react-geo@16.2.2 requires a peer of ol@^6.9 but none is installed. You must install peer dependencies yourself.
npm
has three different types of dependencies:
dependencies
dependencies are used to directly specify packages needed to run your application's code (e.g. a front-end library like Bootstrap)
devDependecies
devDependencies are reserved to specify packages needed to build your application's code (e.g. test harnesses like Jest or transpilers like Babel).
peerDependencies
However, under some conditions, one wants to express
the compatibility of a certain package with the host package and npm calls this
dependency a peerDependencies.
Ususally this is used to express the dependency of a plugin inside this host package
or similiar. In react-geo
we need to have antd
, ol
and react
defined as peer
dependencies due to scope issues, because all of them were usually referenced by
the host package/the application itself in a certain version.
As npm
handles dependencies hierachically, including those packages in react-geo
twice would
lead to two different dependencies available in your application at runtime. To
share the dependencies between your host application and react-geo
, we advice
react-geo
to use the dependencies given by the host package.
To meet these requirements we have to install the requested peer dependencies by ourselves with:
npm i antd ol
Now we're ready to make use of all react-geo
components and utilities inside
our my-app application.
info Due to a breaking change in webpack, we also have to install following dependencies explicitly: npm i buffer
