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.
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
