Expo IHP Backend

07.03.2022, 15:16

I was just trying out a new IHP Backend project based on the expo template. When I check out the templated project and run npm install I'm getting this error:

[nix-shell:~/pymodules/attics-mobile]$ npm install
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: ihp-backend-expo-starter@1.0.0
npm ERR! Found: react@17.0.1

npm ERR! peer react@"^17.0.2" from ihp-backend@0.1.0
npm ERR! node_modules/ihp-backend
npm ERR!   ihp-backend@"*" from the root project

Does this require an upstream PR to the template to bump the react version?

I also had a question about which npm version to use. I've check the project out into a separate repo but would like to integrate it with an existing IHP app. I'm wondering what the best way to ensure that I use a consistent npm version pinned to the same nixpkgs set is?

Just updated the package via https://github.com/digitallyinduced/ihp-backend-expo-starter/commit/81ad1d1a1777452236a6a94180272c9166ed52d2

Can you try out again?

For integrating it into an existing IHP app, I'd suggest to use DataSync directly.

You can include it inside the package.json like this:

{
  "name": "frontend",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "esbuild": "^0.14.23",
    "ihp-datasync": "https://gitpkg.now.sh/digitallyinduced/ihp/lib/IHP/DataSync?3b66d8db44a69a2d58c7b47f18996ce1a74f38bc",
    "react": "^17.0.2",
    "react-dom": "^17.0.2"
  }
}

The last part of the https://gitpkg.now.sh/digitallyinduced/ihp/lib/IHP/DataSync?3b66d8db44a69a2d58c7b47f18996ce1a74f38bc url is the commit hash of the IHP repo itself. If you set that to your project's commit hash, you should have a consistent version
