Starting Persevere from another folder than it was installed in

StackOverflow https://stackoverflow.com/questions/23147474

Question

I installed Perservere with "npm install persevere-example-wiki", as specified here http://persvr.org/Installation. Starting the server from the folder node_modules/persevere-example-wiki DOES work as specified. Here is the server log for my request

$ pwd
PROJECT_ROOT/node_modules/persevere-example-wiki
$ node index.js 
Listening on port 8282
persevere>createContext { id: 'Example',
  content: 'this is a test\n\n   and some other test',
  createdBy: 'admin',
  status: 'published',
  lastModifiedBy: 'qwe123' }
createContext public not found
error writing [object Object]TypeError: first argument must be a string or Buffer

However there are a few things I do not understand: Even though I provided the right database credentials, nothing gets saved in the database server, every data I have entered into the application is saved only in the "node_modules/persevere-example-wiki/data" folder, in plain text JSON files.

How can I start persevere from a different folder than node_modules/persevere-example-wiki? I am convinced there is a way to configure paths, I would like to know how. I tried copying the local.json to the grandparent folder and tried to start from there, but a lot more errors appear:

$ node node_modules/persevere-example-wiki/index.js 

fs.js:427
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

Right now, the Persevere framework itself seems overly complex - or perhaps it's just the documentation problem. Anyway it does not seem a good idea to have a single very complex example. Generally, I prefer building up from smaller examples.

Was it helpful?

Solution

Use the NODE_PATH environment variable to add PROJECT_ROOT/node_modules/persevere-example-wiki as a default directory to search: 

   export NODE_PATH=$PROJECT_ROOT/node_modules/persevere-example-wiki
