I recently added the package "numeric": "^1.2.6" to my project.
In addition, I included the types:
"@types/numeric": "^1.2.1"When attempting to import this into my Angular application:
import * as numeric from 'numeric';I encountered an error on this line:
let x = numeric.solve(m, xs);The error message reads:
ERROR ReferenceError: numeric is not definedIf you are encountering an issue with the numeric package missing an index.js file, you will need to manually add the script reference in your project's angular.json configuration.
angular.json
{
"architect": {
"projects": {
"your-app-name": {
"build": {
"scripts": [] <-- remember to modify this
}
}
}
}
}
After making the necessary adjustment, your configuration should resemble the following example, assuming there are no other custom scripts being imported.
{
"architect": {
"projects": {
"your-app-name": {
"build": {
"scripts": ["node_modules/numeric/numeric-1.2.6.js"]
}
}
}
}
}
Don't forget to stop and restart your ng serve command after modifying the angular.json file for the changes to take effect.
By including the script reference in the angular.json, you make the numeric library accessible through the global window object in the browser as window.numeric.
In addition to this global access, if you have downloaded the corresponding typings, you can import them into your components using
import * as numeric from 'numeric'import * as numeric from 'numeric';
@Component({...}) export class SomeComponent {
x = numeric.solve(x,v);
}
Since the import serves as type information only, it is removed during TypeScript transpilation to JavaScript. Consequently, the numeric functions should work seamlessly as they are globally available on the window object.
