Hello,
I need an answer on this magic question:
I use fs.createWriteStream to write a text file and it is work good at first any times. After any times I'm starting to get EROFS: read-only file system.
What can be a reason of it if then it is work good on non-brightsign-devices every time?
What path are you writing file to?
I use the next path "storage/sd/example.txt" and it is work for long time good but at some time is not work and at debug console i see an error "EROFS: read-only file system"
PS: I checked SD storage value and totally used 125 Mb of 4 Gb
As example:
const fs = require("fs")
...
let writeStream = fs.createWriteStream("storage/sd/example.txt");
writeStream.write(messages.join("\n")); // messages are used as ...messages: string[]
writeStream.end();
...
Try "/storage/sd/..."
With forward slash at the beginning, so the path is absolute instead of relative.
I tried the solution as you wrote and an error are continue meet.
const fs = require("fs");
const root = "/storage/sd";
...
function write(...messages) {
let writeStream = fs.createWriteStream(root + "/example.txt");
writeStream.on("finish", () => console.log("success write"));
writeStream.on("error", error => throw new Error(error));
writeStream.write(messsages.join("\n"));
writeStream.end();
}
...
Is it possible that something are block this?
I don't know if you are supposed to write directly from JS to the SD card.
In the past I found the JS console very helpful.
Best would be to consult with the HTML Best Practice page.

In the past I found the console very helpful too and fully consult with HTML Best Practices but not enough for this problem...
I used createWriteStream/writeFile/writeFileSync and the problem are continue meet..
