What is this library good for ?
engines. It can be used within a browser as well as with Node.js. It handles asynchronous communication
with the devices using Promise objects, leveraging the new EcmaScript 2017
await non-blocking syntax for asynchronous I/O.
Happily 2017 is there, and
Here is your favorite engines minimum version needed to run this code. All of them are officially released at the time we
write this document.
- Node.js v7.6 and later
- Firefox 52
- Opera 42 (incl. Android version)
- Chrome 55 (incl. Android version)
- Safari 10.1 (incl. iOS version)
- Android WebView 55
If you need backward-compatibility with older releases, you can always run
Babel to transpile your code
and the library to older standards, as described at the end of this document.
We don't suggest using
jspm 0.17 anymore since that tool is still in Beta after 18 month, and having to
use an extra tool to implement our library is pointless now that
await are standard.
Using the official Yoctopuce library with node.js
Start by installing Node.js version 7.6 or later on your system, because you'll need it. It is very easy. On Windows, you only have to run the npm installer and that's it. Make sure to install it fully, including npm, and add it to the system path.
To give it a try, go into one of the example directory (for instance
example_nodejs/Doc-Inventory). You will
see that it include an application description file (
package.json) and a source file (
download and setup the libraries needed by this example, run:
Once done, you can start the example file using
Using the local Yoctopuce library with node.js
If for some reason you need to make changes to the Yoctopuce library, you can easily configure your
project to use the local copy in the
lib/ subdirectory rather than the official npm package. In order
to do so, simply type the following command in your project directory:
npm link ../../lib
This will tell node.js to use the version of the library found in the specified path.
Using the Yoctopuce library within a browser (HTML)
For HTML examples, it is even simpler: there is nothing to install. Each example is a single HTML file that you can open in a browser to try it. In this context, loading the Yoctopuce library is no different from any standard HTML script include tag.
npm instal -g babel-cli npm instal babel-preset-env
You would typically ask Babel to put the transpiled files in another directory,
compat for instance. Your files and all files of the Yoctopuce library
should be transpiled, as follow:
babel --presets env demo.js --out-dir compat/ babel --presets env ../../lib --out-dir compat/
Babel has many smart features, such as a watch mode that will automatically refresh transpiled files whenever the source file is changed, but this is beyond the scope of this note. You will find more in Babel documentation.
