Espruino Web IDE on NPM (with Electron)

Posted on Mon 14th, March 2016

Hi,

There's now a version of the Espruino Web IDE that runs under Node.js:

https://github.com/espruino/EspruinoWebIDE#installing-from-npm

It can be installed without Chrome, on Windows, Mac and Linux. At the moment it supports USB, Serial, and Bluetooth Low Energy.

So if you have a BBC Micro:bit or a Nordic device you've got Espruino running on, this is probably what you want (at least until more devices support Web Bluetooth).

This is great to see! Nearly works for me with Pico plugged into Raspberry Pi 3

Needed the following to install it:
```
sudo apt-get install libudev-dev
sudo npm install --unsafe-perms -g espruino-web-ide
```
But when I click Connect, I just get "Searching" in the ports popup. Tried with and without sudo. Also tried passing /dev/ttyACM0 as a parameter. No error printed out in terminal or inside the IDE's log.

Any ideas?

Try espruino-web-ide --dbg - I think this should give you a debugger window on the right-hand side where you can see errors reported.

I'd be 99% certain it's saying something like can't find serialport v47 - it's what happens when the version of node (node --version) doesn't match the version of electron, so the compiled libraries installed by npm don't work.

Sadly it seems to be a major problem with both nw.js and electron, but it's usually just fixed by upgrading node.js

No joy with --dbg. Nothing new appeared.

But Node versioning sounds like the problem alright. I'm on 4.4.0 (Raspbian ships with 0.10.x)

Actually I just looked at this a bit more and it seems that you can npm install electron-rebuild, run it, and then it'll rebuild everything for electron's version. That will probably sort it out for you...

Looks like it can go in package.json so it all happens automatically, but I'm not 100% sure how to do that at the moment.

No joy with that but it may be user error. I'll try again later.

No success with starting back with completely clean slate (all node_modules and .node-gyp directories deleted) and just doing npm install espruino-web-ide. Now it won't even install.

Try again now - I'd added some extra code that called electron-rebuild automatically as had been suggested on the net - but it looks like it's broken.

(It seems to expect electron on the path, which is fine I guess if you installed it globally before, but it doesn't work for a simple npm install)

It now builds again but still no serial ports.

I also tried

sudo electron-rebuild --version 0.36.11

giving

Couldn't find electron-prebuilt and no --node-module-version parameter set, always rebuilding

I need to try on a non-RPi box to see if it's Pi or ARM specific.

• #11

Gordon

Ahh - might be an idea. I haven't tried it on the Pi...

If only someone could come up with a serial port library that didn't need native modules. I would have thought just opening the file /dev/ttyACM0 would be good enough - although maybe it's too hard to do on Windows and Mac as well.

conor

Yeah it's a pain.

Just FYI - Exact same behaviour/error as the last one above with Node 4.2.6 on Fedora 23 x86-64 in a VBox VM.

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

Mention another user by @username

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
