I'm trying to import a file that is in the rails asset pipeline and for some reason webpack can't find it.
Here is my tsconfig.json:
{
"compilerOptions": {
"declaration": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es6", "dom"],
"module": "es6",
"moduleResolution": "node",
"sourceMap": true,
"target": "es5",
"baseUrl": ".",
"paths": {
"@images/*": ["app/assets/images/*"],
}
},
"exclude": [
"**/*.spec.ts",
"node_modules",
"vendor",
"public"
],
"compileOnSave": false
}
Here is my config/webpack/environment.js:
const { environment } = require('@rails/webpacker')
const customConfig = require('./custom');
const typescript = require('./loaders/typescript')
const fileLoader = require('./loaders/file');
environment.loaders.append('file', fileLoader)
environment.loaders.append('typescript', typescript)
// Merge custom config
environment.config.merge(customConfig);
module.exports = environment
My config/webpack/custom.js:
const path = require('path');
module.exports = {
resolve: {
alias: {
'@src': path.resolve(__dirname, '..', '..', 'app/javascript'),
'@images': path.resolve(__dirname, '..', '..', 'app/assets/images'),
'@components': '@src/components',
React: 'react',
ReactDOM: 'react-dom'
}
}
};
import "@images/ajax-circle.gif";
in one of my typsecript files gives error 2307 (can't resolve module) and webpack-dev-server
is unable to compile with the following error:
ERROR in /Users/brandoncc/dev/my_app/app/javascript/lib/store_management.ts
[tsl] ERROR in /Users/brandoncc/dev/my_app/app/javascript/lib/store_management.ts(1,24)
TS2307: Cannot find module '@images/ajax-circle.gif'.
webpack: Failed to compile.
It looks like the error comes back to typescript not being able to resolve the file, but I can't figure out why it can't find it.
It turns out that I needed to add a definition for the .gif extension.
Creating
typings.d.ts
with:fixed it.
If you are relying on typescript
paths
feature, you need to usetsconfig-paths-webpack-plugin
that will resolve the path correctly. Just add that to your webpack config
