|First public release

==Introduction==
Nowadays several designs are based on the latest Javascript technologies available for implementing advanced (Industrial) Graphical User Interface in an easy way.
Mito8M is the first DAVE Embedded Systems' product based on a core implementing the [https://en.wikipedia.org/wiki/ARM_architecture#64/32-bit_architecture ARMv8-A] architecture.
Specifically, it is built upon the [https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i.mx-applications-processors/i.mx-8-processors/i.mx-8m-family-armcortex-a53-cortex-m4-audio-voice-video:i.MX8M NXP i.MX8M] system-on-chip (SoC).
Similarly to the Technical Note written for the [[:Category:SBC-AXEL|SBC Axel]] platform using the [[:Category:AxelLite|AXEL Lite SOM]], this Technical Note (TN) describes how to install the well known [https://nodejs.org/en/ node.js] runtime and the [https://www.electronjs.org/ electron.js] application framework.
Both '''node.js''' and '''electron.js''' allows to create desktop applications in JavaScript, HTML, and CSS.
Electron uses web pages as its GUI, so you could also see it as a minimal Chromium browser, controlled by JavaScript.
(''[https://www.electronjs.org/docs/tutorial/first-app rif. electron tutorial]'')
More information about '''electron''' can be found on [https://www.electronjs.org/ its web site]. It is useful to follow the [https://www.electronjs.org/docs/tutorial/quick-start Quick start guide] and the complete [https://www.electronjs.org/docs documentation].
===Testbed configuration===
Due to the '''Mito8M electrical and mechanical compatibility with [[:Category:AxelLite|AXEL Lite]]''', the testbed used for this TN is pretty similar to the one described [[SBCX-TN-007:_Enabling_node.js_and_electron.js_for_creating_Javascript_applications|here]]. Even though the SBCX carrier board is designed to host Axel Lite, in fact, '''it supports Mito8M as well'''.
[[File:SBCX-Mito8M.jpg|thumb|center|500px|Mito8M SoM on SBCX carrier board]]
For what concerns software, the following configuration was used:
* Linux kernel: <code>4.14.78-mito-0.9.0</code>
* Yocto Sumo root file system
== Installation ==
===node.js ===
The ''node.js'' runtime environment can be easily installed using its [https://github.com/nvm-sh/nvm Node Version Manager]. The <code>nvm</code> package manager allows to install multiple node instances and manage them.
====Installing node.js ====
Once ''nvm'' is installed, simply ask it for installing the latest '''LTS''' version of node.js:
<pre class="board-terminal">
root@imx8mmevk:~# nvm install --lts
Installing latest LTS version.
Downloading and installing node v12.18.2...

Then, using ''npm'', it is possible to install the '''electron''' framework, just execute the following command:
