Important: Expects an HAPP built with HDK ~v0.2.2 and HDI ~v0.3.2

An alternative Holochain conductor binary useful for quick startup and including handling of key generation and hApp installation. Useful for production and development environments.

manage holochain processes during an electron application runtime, using holochain-runner binary.

await shutdown()

Updating holochain-runner version and releasing

Go to ./src/downloadBinaries.ts and search for 'version-bump'. Change the value of const holochainRunnerTag = 'v0.7.9' to the version of holochain-runner you want to bundle. This will instructs clients to download that version of the holochain-runner binary from Github, during npm install.

To get this to trigger, run npm run try-binary-download.

Publishing

Bump the package.json version. Commit. Tag. Push. Run npm run build to build the typescript. Then run npm publish --access public to publish to npmjs.com.
