locusmaps-sdk
This project contains a small script which can be used to initialize and control a LocusMaps instance. It is sometimes referred to as the "SDK Client".
The emphasis here is that this script remains extremely small (about 2k gzipped) - and does not change very often. Also, the resources required to display a map are not downloaded until and unless you request a map to be shown. So if there are conditions in which a map may not shown, there is very little penalty to have loaded or included this script into your web page.
If you do initialize a map on the page, a resource bundle is downloaded which contains all the map rendering and controlling code. This resource bundle is loaded from LocusLabs servers - it is referred to as the "SDK Server Bundle".
Usage
There are several ways to get the SDK client incorporated into your web site or web application. Using a package manager, such as npm or yarn - or by simply adding a script tag to your web page.
Installation via npm / yarn
The SDK client is registered with npmjs as locusmaps-sdk, so you may install via:
npm install locusmaps-sdk
# or
yarn add locusmaps-sdkYou can then use in either ES6 module style (import) or CJS module style (require).
ES6 Module Style
import LMInit from 'locusmaps-sdk'CJS Module Style
const LMInit = require('locusmaps-sdk')Using LMInit
Then, when you are ready to initialize the map with a given config:
LMInit.newMap('#map', config)
.then(mapReady)
.catch(e => console.error('Error initializing map: ', e))
function mapReady(map) {
// Your map is ready to use here!
}Using Directly in your HTML
If you don't use a bundler, we have also made the script available via UMD (Universal Module Definition) and ES6 bundles to be injected directly to inject into your webpage.
UMD
The UMD bundle is compatible with Require.js or as a standalone <script> insertion:
Require.js (also known as AMD)
To use with RequireJS, simply refer to the URL of the UMD in your require call:
require(['https://maps.locuslabs.com/sdk/LocusMapsSDK-umd.js'], LMInit => {
const config = { /* ... */ }
LMInit.newMap('#map', config)
.then(mapReady)
.catch(e => console.error('Error initializing map: ', e))
})
function mapReady(map) {
// Your map is ready to use here!
}Directly on page (ES5)
This approach simply injects the UMD script directly on the page, which exposes the LMInit global variable:
<head>
<script src="https://maps.locuslabs.com/sdk/LocusMapsSDK-umd.js"></script>
<script>
const config = { /* ... */ }
LMInit.newMap('#map', config)
.then(mapReady)
.catch(e => console.error('Error initializing map: ', e))
function mapReady(map) {
// Your map is ready to use here!
}
</script>
</head>ES6 modules
If you are embracing the most recent module format, the ES6 Module format, then you can use the ES6 module build directly as well:
<head>
<script type="module">
import LMInit from 'https://maps.locuslabs.com/sdk/LocusMapsSDK.js'
const config = { /* ... */ }
LMInit.setLogging(true)
function go() {
LMInit.newMap('#map', config)
.then(start)
.catch(e => console.error('Error initializing map: ', e))
}
function start(map) {
// Your map is ready to use here!
}
</script>
</head>
