Cuely search app

This repo contains the code and configurations to run Cuely frontend/desktop app. Currently, it only works well on macOS.

Overview

Cuely is a service that indexes your cloud app accounts (Goggle Drive, Github, Trello, ...) and makes all the indexed data available in one place. Aim is to have the searches as fast as possible, while still having a structured view of the data. Therefore, the client(s) can be made fast, informative and showing the data that is up to date.

Cuely search app is an Electron app that can be used as a search bar (similarly to Spotlight or Alfred). In theory, an Electron app can be run on all major operating system (Windows, Linux, macOS), however there are hard macOS dependencies in the Cuely code as well as building, signing and updating mechanisms. It would need some work to make it run properly on Windows or Linux.

The search app connects to Cuely backend for logging in, adding integrations, and so on, but uses Algolia to perform searches. To replace Algolia with another search engine there would be some work to do both here in the app code as well as backend code.

Development

Make sure that you have NodeJs installed (tested with v6.3.1) along with npm, then run npm install to get all the dependencies. Then, copy env_TEMPLATE.js file to env_dev.js and env_prod.js and modify them according to your environment.

For development the running setup is a bit complicated, because we want to have hot-reload of changed code/html/css. Luckily, all is hidden away in the package.json file, so to run the app just type: npm run dev. Of course you also need Cuely backend instance up and running as well as Algolia account (there's a free tier available).

Production builds

Making an app installable/usable at users' computers involves a bit more work. First, one needs to be a member of Apple Developer Program to get the certificate used for signing the app. Self signed certificates or certificates issued by other non-official authorities are useless, e.g. macOS will reject running such apps. There are different certificates needed, depending on intended use of the app. Simplest variant, installing and running the app outside of app store, requires Developer ID Application certificate. To have the app present in the app store involves other certificates as well as app review process by Apple, which is outside the scope of this README.

To find out if there are any valid code signing certificates present, use security find-identity command:

$ security find-identity -v -p codesigning
97387061A6DC060551BCC82123810ADC16E9ED18 "Developer ID Application: My company ltd. (D1273L56AC)"

If there is a Developer ID certificate listed, then you can use it to sign the Cuely app. Remember to use the long id (97387061A6DC060551BCC82123810ADC16E9ED18) to replace the 'certificate_id' in build directive in package.json.

To build and sign the app, run:

npm run build

After build is done, check if signature is correct by using codesign tool:

$ codesign -dv Cuely-darwin-x64/Cuely.app
Executable=.../cuely-search/Cuely-darwin-x64/Cuely.app/Contents/MacOS/Cuely
Identifier=com.cuely.search
Format=app bundle with Mach-O thin (x86_64)
CodeDirectory v=20200 size=272 flags=0x0(none) hashes=3+3 location=embedded
Signature size=8909
Timestamp=20 Mar 2017, 13.26.38
Info.plist entries=20
TeamIdentifier=DRD73LRQEC
Sealed Resources version=2 rules=13 files=10427
Internal requirements count=1 size=176

Output shows correctly signed app details. If the output is something like bundle format unrecognized, invalid, or unsuitable or code object is not signed at all, then signing of the app failed.

Deploys/updates

Updating the app once it's been installed at a user's machine is a multi-step process:

  1. One needs to setup an update server, which must be capable of returning a proper response (either url to new version or nothing if version is unchanged)
  2. Cuely app then periodically pings this server for new updates.
  3. If a new update is available, then Cuely will download new version and restart.

See sibling repository cuely-updates to see how the update server works. To make all pieces work, one needs also a place to upload new versions. package.json contains deploy directive which uses Amazon S3 to deploy the zipped build. Tailor this solution to your needs/your environment. At the very least, you must change S3 bucket in the deploy directive.

To deploy a new version:

  1. Bump the version in package.json
  2. Run command: npm run deploy
You can’t perform that action at this time.
