sqlite - anyone use it?

bobt

If I just send back data without using the sqlite3 it works too.

sdetweil

@bobt so, it works ok?

bobt

@sdetweil It works with fine serveronly. Gets data from the db and passes it to the script. But without the serveronly it chokes when it sees the var sqlite3 = require(“sqlite3”);

[2020-04-01 20:36:15.609] [ERROR] Error: Cannot find module ‘/home/pi/MagicMirror/node_modules/sqlite3/lib/binding/electron-v6.0-linux-arm/node_sqlite3.node’

The module exists in /home/pi/MagicMirror/node_modules/sqlite3/lib/binding but not in the electron folder.

No idea. I can’t just copy it in - version numbers don’t match.

sdetweil

@bobt for your module, you added that as a dependency in package.json, then do an npm install in your module folder.

it should be in

‘/home/pi/MagicMirror/modules/modulename/node_modules/sqlite

bobt

@sdetweil Thank you Sam for all your help. I created that folder and just copied the module in. I get:

[2020-04-02 07:42:08.104] [ERROR] WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module ‘/home/pi/MagicMirror/node_modules/sqlite3/lib/binding/electron-v6.0-linux-arm/node_sqlite3.node’

I’m ready to just start over. If I started with a fresh install of MM and wanted to install sqlite how would I go about it? Should I be in the module folder? the MM folder?
Thanks again for your help.

sdetweil

@bobt as its used by the module, it should be in the module folder

just copy is always bad

npm install sqlite --save

–save will put it into the package.json in this folder

you should have one(package.json), then u can keep track of your dependencies…

npm init will create one

bobt

Thanks - and one (hopefully last) question. If I wanted sqlite to be available for a number of modules where would I put it?

sdetweil

@bobt i don’t know

u might be able to put in in the base, and then change your require to include the path to the ~/MagicMirror/node_modules/sqlite version

Perlchamp

@bobt
did u find a solution for your problem ?

sdetweil

@Perlchamp you should create a package.json for the module
by doing npm init in the module folder, and answering the setup questins.
the questions only add text to the package.json, nothing else

and then

then install your dependencies

npm install --save sqlite3

–save means add this to the package.json dependencies section

when u are done, you can send the package.json to another person,
and they can run npm install in the module folder and get the same
supporting code installed for this module

and if you asked for a SPECIFIC version of some library,
that would be recorded in the package.json too, so the other user would get
the same level of the dependency
