edited April 2018 in Mongoose OS

I'm a bit confused what libraries I should use in my mos.yml file?

I originally had:

  - origin:
  - origin:
  - origin:
  - origin:
  - origin:
  - origin:

which fails for some reason I have replaced it with:
- origin:

but I have no idea what this library does is that a recommended list of libraries for specific functions?

eg rpc, mqm and gpio etc..
do I need a wifi library?

    The list of libraries you should use depends on what you'd like to achieve

    I added all above libraries and compile failed, what is the problem?

    Compilation can fail for a lot reasons.
    If you don't give more information, nobody can help.

    attaching file

    It looks like you have in the project's fs directory the following files and the corresponding libraries are not listed in the libs section of mos.yml:
    api_adc.js, api_aws.js, api_i2.js, api_pwm.js, api_shadow.js, api_spi.js

    These files should not be added in the fs directory. If the corresponding library exists in the libs section, the build process will add it automatically.
    Delete them from fs and add only the libraries you use. load the files you are using in init.js.

    Example: if you need i2c

     - origin:

    and in config.schema

     - ["i2c.enable", true]

    Read the mos.yml (and mos_esp8266.yml, if exists) of the library you want to use. It will give you more hints about the way to use the library.

    ok I know a bit more cheers.
    I couldn't see those files in my "fs" folder so I don't know what is wrong, but I cloned the "empty" project and pasted my code into that and that compiles ok now.

    thanks again.
