TypeScript's tsconfig.json sets paths to
Parcel's ~ module resolution convention
and baseUrl to src directory.
Parcel is given src/index.html as its input,
which references src/entrypoint.tsx.
All TypeScript files in src
may use the ~ non-relative import paths.

I use "esModuleInterop": true for default import (it's only my preference).
I've got my project set up like this:
├── package.json ├── public │ ├── index.html ├── src │ ├── index.tsx │ ├── App.tsx │ └── components │ └── InboxScreen │ └── index.tsx │ └── Task │ └── index.tsx │ └── TaskList │ └── index.tsx └── tsconfig.jsonand my tsconfig.json set up exactly like yours. Typescript is happy with it, but parcel throws an error:
/c/Users/username/Projects/taskbox/src/components/InboxScreen/index.tsx:3:21: Cannot resolve dependency '~/components/TaskList' at '/c/Users/username/Projects/taskbox/src/components/InboxScreen/~/components/TaskList'No idea what I'm doing wrong here... Any insight?
it look weird... why it search file from
taskbox/src/components/InboxScreen/but notsrc.
i think it must be something wrong in tsconfig, for example baseUrl
{
"compilerOptions": {
"target": "ES2019",
"lib": [
"dom",
"dom.iterable",
"esnext"
],
"allowJs": true,
"skipLibCheck": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"strict": true,
"forceConsistentCasingInFileNames": true,
"module": "esnext",
"moduleResolution": "node",
"resolveJsonModule": true,
"isolatedModules": true,
"noEmit": true,
"jsx": "react",
"baseUrl": "./src",
"paths": {
"~/*": ["./*"]
},
},
"include": [
"src/**/*", "@types"
]
}That's how I've got my tsconfig set up. The baseUrl and paths are set up correctly.
I have the same problem as @schematis. Typescript resolves the modules correctly, IDE is showing code completion like it's supposed to, but parcel crashes on first occurrence of '~' module resolution notation.
{
"compilerOptions": {
"baseUrl": "./src",
"jsx": "react",
"esModuleInterop": true,
"paths": {
"~*": ["./*"]
}
},
"include": ["src/**/*"]
}
I'm not working on any TypeScript + Parcel projects at the moment but if someone has an updated working version, I can try to replicate locally and then update the original Gist for future folks.
Can someone help me please? I'm trying to do that but it's not working well.

I think your baseUrl needs to be as follows.
"baseUrl": "./src",
