Planned or unsure Diaspora behaviors/features

Manual change of properties

Unsure > Entity may change status to desync ?

P2P Adapter

Unsure > May be interesting... Check for possible problems about data modification, etc etc.

IndexedDB Adapter (browser)

Unsure > IndexedDB technology may be too immature. See MDN about IndexedDB. Note: Plan to show fallback implementations

Working with the development version

If you are having issues, or you want to participate to the development and create new features, you may have to use the development or staging version of Diaspora. Here is how you can do that:

# Clone the repository & go into it
git clone https://github.com/diaspora-orm/diaspora.git && cd diaspora
# Go on the staging branch (you can also use directly the `develop` branch, but it may be less stable)
git checkout staging
# The following command installs dependencies & compiles the package
npm run build
# Finally, expose your local build so that it can be used in other projects.
# You may need to run it with `sudo`.
npm link

# Go to your project
cd ~/myproject
# Ensure deps are installed
npm install
# And link the local version
npm link @diaspora/diaspora

Note that you may need to re-run npm link @diaspora/diaspora after every install (npm install) in your project.
