I am trying to install fonts with
react-native link ./assets/fonts/ and with react-native link
both are giving the same error:
"error Failed to get dependency config."
I updated my package.json
"rnpm": {
"assets": [
"./assets/fonts/"
]
}
Please help
I have made sure the path to the font folder is correct and still same problem
re-install and re-link solves the problem in my case
What version of your react-native?
If it is> 0.60, it is recommended to create the react-native.config.js file with the configurations below:
module.exports = {
project: {
ios: {},
android: {}, // grouped into "project"
},
assets: [
'./assets/fonts/',
],
};
Link without specifying the package name and it should work
react-native link

I have one react-native app in which I am using "json-schema-rules" library. Now I have also created one library which is getting used in my react-native app like this "file:../custom_library" in package.json.
Now to resolve the version conflict, I decided to use "json-schema-rules" as a peer dependency in my custom library. So, the package.json is like this
Package.json of my react-native app:
{
"dependencies": {
"json-rules-engine": "^2.3.0",
"custom_library": "file:../custom_library"
}
}
package.json of my custom_library:{
"peerDependencies": {
"json-schema-rules": "^2.3.0"
}
}
Now the problem is, whenever I am using metro bundler, I get an error
error: bundling failed: Error: Unable to resolve module json-rules-engine
json-rules-engine could not be found within the project.
This is the case when I am using it in peerDependencies, I do not get any error if I use this library in dependencies.
Please help.
You can try to add an alias for the module in your project's babel config.
This means that when your custom packages tries to import "json-rules-engine" it will get served the version from the main app.
First install 'babel-plugin-module-resolver' then configure the alias in "module-resolver"
babel.config.js
const config = {
presets: ["module:metro-react-native-babel-preset"],
plugins: [
[
"module-resolver",
{
root: ["./src"],
extensions: [".js", ".jsx", ".ios.js", ".android.js"],
alias: {
"json-rules-engine": require.resolve("json-rules-engine")
}
}
]
]
};
module.exports = config;
I'm trying to link a large number of font files into my react-native project and I don't want to do it manually because of how many there are.
Most instructions I've found say to do this:
package.json
"rnpm": {
"assets": ["assets/fonts"]
}
and then react-native link
The problem is I can't run react-native link without a second argument as it causes problems with some of the libraries I have installed.
Is there a way I can specify the command so it only links assets?
first edit your package.json
"rnpm": {
"assets": [
"./assets/fonts/"
]
}
then run
react-native link ./assets/fonts
source
I couldn't find a solution without running react-native link either. My solution was to commit everything, clean your stage, run react-native link, then check the git diff and remove the ones that is not your fonts. Works for me.
For example:
package.json
"rnpm": {
"assets": [
"./assets/Fonts/"
]
},
now you can use
react-native link
Here is what worked for me:
Create a configuration file react-native.config.js in the root project directory and add the code below:
module.exports = {
project: {
ios: {},
android: {},
},
assets: ['./assets/fonts'],
};
Then run npx react-native link
Here is the article: https://medium.com/#aravindmnair/add-custom-fonts-to-react-native-0-60-easily-in-3-steps-fcd71459f4c9
react-native: 0.60.4,
react: 16.8.6,
npm: 6.10.1
XCode: 10.2.1
AndroidStudio: 3.4.1
I created a project using
npx react-native init awesomeApp --template typescript
I have put my assets in the
assets/fonts/<Bunch of .ttf files>
My Directory Structure
awesomeApp
|
+--android
+--ios
+--assets
| |
| +---fonts
| |
| +-- ProximaNova-Bold.ttf
+--react-native-config.js
then I ran
react-native link
Nothing happends, XCode not showing any added Resource neither the android, and when I'm running react-native run-ios showing error that the font is not found.
My react-native-config.js
module.exports = {
project: {
ios: {},
android: {},
},
assets: ['./assets/fonts']
};
I have also tried
yarn react-native link and npx react-native link
Well,
finally, I linked my fonts,
I just renamed my file react-native-config.js to react-native.config.js and it worked.
I don't know if this is the right way, I just tried and it worked, for me at least.
Here is the complete walkthrough for linking custom fonts.
my react-native.config.js
module.exports = {
project: {
ios: {},
android: {},
},
assets: ['./assets/fonts/'],
};
and logs:
info Linking assets to ios project
info Linking assets to android project
success Assets have been successfully linked to your project
but My mistake was:
Wrong way:
fontFamily: BYekan
Right way:
fontFamily: 'BYekan'
just put font name in ''
For React-native > 0.69, npx react-native link is no longer working
Use npx react-native-asset instead
Just to complement keyserfaty's answer, here is my react-native.config.js working using react-native link:
module.exports = {
dependencies: {
"react-native-gesture-handler": { platforms: { android: null, ios: null } }
},
assets: ['./src/assets/fonts']
};
Create a file in your react native project called react-native.config.js:
In it, paste
module.exports = {
project: {
ios: {},
android: {},
},
assets: ['./src/assets/fonts/'],
};
assets: ['./src/assets/fonts/'], should be the path to wherever you stored your custom fonts in your project folder.
When you run the link command, it should work then.
Using RN 0.60.8 with a react-native-config.js file should allow you to link your fonts using react-native link.
My logs:
react-native link
info Linking assets to ios project
info Linking assets to android project
success Assets have been successfully linked to your project
Since you installed React Native using npx I'm guessing you maybe don't have react-native installed globally? Is running react-native link giving you any errors?
None of the above solutions work for me. The issue with what I was having is my Xcode project already had Resources group with a backed folder in it. The way react-native link is working as my understanding is it's creating a group without a folder and add it to your project and link to all your fonts from there. This approach doesn't work when you already have a Resources folder. The solution I could come up with was just renaming the Resources folder to something else and run react-native link again.
If you don't have such a setup, create react-native.config.js file and running react-native link works fine.
react-native.config.js
module.exports = {
project: {
ios: {},
android: {},
},
assets: ['./src/assets/fonts/']
};
change assets: ['./src/assets/fonts/'] to assets: ['/src/assets/fonts/']
or use
assets: ['./src/assets/fonts/'] but nameProject/assets
some times you have writed react-native.config.js correctlly
in such cases ; if you do this tasks
it helps you
1- delete react-native.config.js file
2- create this file with same code again
3- write react-native link in console
then you can see resources folder in Xcode
and you can see your fonts in info.plist and copy bundle resources
The "adding the font" should be done in your package.json. Add:
"rnpm": {
"assets": ["./assets/fonts/"]
}
Then run
react-native link

EDIT: The above only works for react-native below 0.60.0
I have followed the steps outlined in the VS Code documentation for getting Intellisense working for React Native by installing typings for React Native. Now, what do I need to do to get autocomplete working? For instance, if I type <Text>, I would like to see an automatic closing of that tag. What am I missing here? This seems like it shuld work out of the box.
To enable IntelliSense (autocomplete) you have to install the official React Native Tools extension.
Installation
Open Command Palette by pressing F1, type ext install and press Enter, then look for React Native Tools extension.
Create a jsconfig.json file
You should create a jsconfig.json file in you root directory. It can be empty but must be present. The presence of such a file in a directory indicates that the directory is the root of a JavaScript project.
(Optional)
The file itself can optionally list the files belonging to the project, the files to be excluded from the project, as well as compiler options.
{
"compilerOptions": {
"target": "ES6",
"module": "commonjs",
"allowSyntheticDefaultImports": true
},
"exclude": [
"node_modules"
]
}
You can find more at https://code.visualstudio.com/docs/languages/javascript#_javascript-projects-jsconfigjson
Create a .babelrc file for ReactNative Packger transformer (optional, if you want to use TypeScript)
You should create a .babelrc file with sourceMaps = true and "presets": [ "react-native" ] for better source-mapping support. (required if you want TypeScript support).
{
"presets": [
"react-native" // this is required for debugging with react-native/packager/transformer
],
"plugins": [],
"sourceMaps": true // must be true react-native/packager/transformer using with node-module-debug
// because of some bugs from vscode-node-debug & vscode-react-native, "sourceMaps" cannot be "inline" or "both"
}
Install typings for React Native (optional)
To get IntelliSense for React Native, run npm install typings -g and then typings install dt~react-native --global in your terminal.
Hope this helps!!
React Native Tools in VSCode can't help you close the Tag after you typed<Text>,you can try to install Auto Close Tag and Auto Rename Tag
In my case, I have to copy jsconfig.json to tsconfig.json, close Visual Code and reopen it. Then it works properly.
jsconfig.json
{
"compilerOptions": {
"allowSyntheticDefaultImports": true
},
"exclude": [
"node_modules"
]
}
tsconfig.json
{
"compilerOptions": {
"allowJs": true,
"allowSyntheticDefaultImports": true
},
"exclude": [
"node_modules"
]
}
I am also not getting any IntelliSense and also package auto-import is not working. Since I am not using Typescript, deleting the tsconfig.json helped me.
Take backup of your tsconfig.json file first
In my case, I've already installed many react-native extensions for autoSuggestion and another helper extension, e.g. "React Native Tools", and "React-Native/React/Redux snippets for es6/es7"
Issues:
autoSuggestion keywords not coming while typing.
command(in IOS) + click not letting me to jump on the target files.
Recently I have seen in VS Code editor for new React-native applications autoSuggestion not working.
Steps I have followed to solve:
Go to Extensions
Search for React or React-native
Remove the installed extension
Reload it.
When I'm launching my project using React-Native default packager, I have this error: Unexpected token on this line:
static propTypes = {
/// ...
};
I took a look on React-Native issues on GitHub, but I didn't find a solution.
Any suggestion?
React-Native packager use Babel for transfer ES6 and ES7, but NOT ALL features. The enable list is here. In your case, class-props is not enabled by default in RN packager. You can use Babel to compiler your code before packager, or just enable it in the packager setting. See this official doc for more information.
Try appending your propTypes to your class:
var MyClass extends React.Component {
....
}
MyClass.propTypes = {
.... /* enter proptypes here */
}
After #Fomahaut answer, I keep looking on Facebook's GitHub repository and found this issue: https://github.com/facebook/react-native/issues/2182
Create a .babelrc file at the project's root directory
Add more rules to Babel
Example:
{
"retainLines": true,
"compact": true,
"comments": false,
"whitelist": [
"es6.arrowFunctions",
"es6.blockScoping",
"es6.classes",
"es6.constants",
"es6.destructuring",
"es6.forOf",
"es6.modules",
"es6.parameters",
"es6.properties.computed",
"es6.properties.shorthand",
"es6.spread",
"es6.tailCall",
"es6.templateLiterals",
"es6.regex.unicode",
"es6.regex.sticky",
"es7.asyncFunctions",
"es7.classProperties",
"es7.comprehensions",
"es7.decorators",
"es7.exponentiationOperator",
"es7.exportExtensions",
"es7.functionBind",
"es7.objectRestSpread",
"es7.trailingFunctionCommas",
"regenerator",
"flow",
"react",
"react.displayName"
],
"sourceMaps": false
}
According to this answer, you need to install a plugin for class properties as of Babel 6.
As of Babel 6, you now need the transform-class-properties plugin to
support class properties.
Steps:
Run this: npm install babel-plugin-transform-class-properties
Add this to your .babelrc: "plugins": ["transform-class-properties"]
(Note, it's a plugin, not a transform; so don't put it in the "presets" list.)
Worked for me.
Install the stage-0 Babel preset (npm i --save-dev babel-preset-stage-0) and add it to .babelrc file's presets section, e.g.:
{ "presets": ["react", "es2015", "babel-preset-stage-0"] }
See if that helps:
$ npm install babel-plugin-transform-decorators
navigate to /<your project root>/node_modules/react-native/packager/react-packager/.babelrc
Add "transform-decorators" to this list:
{
"retainLines": true,
"compact": true,
"comments": false,
"plugins": [
"syntax-async-functions",
"syntax-class-properties",
"syntax-trailing-function-commas",
"transform-class-properties",
"transform-es2015-arrow-functions",
"transform-es2015-block-scoping",
"transform-es2015-classes",
"transform-es2015-computed-properties",
"transform-es2015-constants",
"transform-es2015-destructuring",
["transform-es2015-modules-commonjs", {"strict": false, "allowTopLevelThis": true}],
"transform-es2015-parameters",
"transform-es2015-shorthand-properties",
"transform-es2015-spread",
"transform-es2015-template-literals",
"transform-flow-strip-types",
"transform-object-assign",
"transform-object-rest-spread",
"transform-react-display-name",
"transform-react-jsx",
"transform-regenerator",
"transform-es2015-for-of",

],
"sourceMaps": false
}
