javascript - React Native component dependency which requires rnpm link -

i created component react-native push npm package. although i'm facing issue.

the component dependent of npm package called react-native-image-resizer. package needs linked rnpm in order work.

although, when install component in brand new project, dependency won't linked automatically, , native library won't appear in project. of course, when run rnpm link, won't add project either.

so i'm wondering best way install , link dependency?

macbook-pro:example $ npm install react-native-image-crop  > react-native-image-crop@1.0.0 preinstall /users/alexmngn/work/react-native-image-crop/example/node_modules/.staging/react-native-image-crop-95365d1b > npm install --save react-native-image-resizer  react-native-image-crop@1.0.0 (git+ssh://git@github.com/alexmngn/react-native-image-crop.git#90e002c7d0f01c9d61277c30cad375560f09a94a) /users/alexmngn/work/react-native-image-crop/example/node_modules/.staging/react-native-image-crop-95365d1b ├── unmet dependency react-native@^0.31.0 └── react-native-image-resizer@0.0.9   npm warn react-native-image-resizer@0.0.9 requires peer of react-native@>=v0.14.2 none installed. npm warn react-native-image-crop@1.0.0 no repository field. - react-native-image-resizer@0.0.9 node_modules/react-native-image-crop/node_modules/react-native-image-resizer example@0.0.1 /users/alexmngn/work/react-native-image-crop/example └── react-native-image-crop@1.0.0  (git+ssh://git@github.com/alexmngn/react-native-image-crop.git#90e002c7d0f01c9d61277c30cad375560f09a94a)  macbook-pro:example $ rnpm link macbook-pro:example $ # nothing gets linked here... 

also, can see there, have unmet peer dependencies issue react-native when install component in example project, though listed (with right version) in dependencies in package.json:

{   "name": "example",   "version": "0.0.1",   "private": true,   "scripts": {     "start": "node node_modules/react-native/local-cli/cli.js start"   },   "dependencies": {     "react": "15.2.1",     "react-native": "^0.31.0",     "react-native-image-crop": "git+ssh://github.com/alexmngn/react-native-image-crop.git"   } } 

any idea why complains?

repo of component available here: http://github.com/alexmngn/react-native-image-crop.git

thanks

the rnpm link links packages found in package.json, these packages installed via command rnpm install or npm install --save.

in order automatically install package, can write preinstall npm script executed before package installed.

in thepackage.json add scripts block this

{   "scripts": {     "preinstall": "npm install --save react-native-image-resizer@0.0.9"   } } 

after doing this, when try install pacakge via npm, react-native-image-resizer installed first, , add leave ab entry package.json -> dependency rnpm link can work correctly.
