How to fix tsc-watch restarts when test file uploading? - file

Question

I want to test file uploading API locally in my NestJS project. I have followed this doc. However, when I uploaded files the tsc-watch restart since the upload folder is changed.
Here I am using NestJS version 6 and everything installed from nest-cli. I am also using Google Cloud Storage to store the files. I test the project locally by running yarn start:dev.
I have tried adding upload folder in exclude option in both tsconfig.json and tsconfig.build.json but it does not work.
I have also tried using nodemon. Unfortunately, nodemon does not restart when I make change to the code.
Here are some codes (repo here):
controller
#Patch(':id/file')
#UseInterceptors(
FileInterceptor('file', { dest: join(__dirname, '../../upload') }),
)
async uploadProblem(
#UploadedFile() file: FileDto,
#Param('id') id: string,
) {
if (file) {
await this.service.uploadProblem(id, file);
} else {
throw new BadRequestException('No files uploaded');
}
}
service
async uploadProblem(id: string, file: FileDto) {
const problem = await this.findById(id);
await this.fileService.uploadFile(`${problem.code}/problem`, file);
}
fileService
async uploadFile(name: string, file: FileDto) {
await this.bucket.upload(file.path, {
destination: name,
contentType: file.mimetype,
resumable: false,
});
removeSync(file.path);
}
package.json
{
...
"scripts": {
...
"start:dev": "tsc-watch -p tsconfig.build.json --onSuccess \"node dist/main.js\"",
...
},

},

}
I expect the file to be uploaded and deleted afterward, but tsc-watch keeps restarting and never upload nor delete the file.
Is there anyway to stop tsc-watch from restart when upload directory is changed, or is there any other tools should I use?

Answer 1

The first solution, using ts-lint is to move the upload folder outside the src folder and ignore that folder.
Another solution is the same as you suggest, using nodemon with ts-node, but nodemon itself has the problem of watching files inside docker and change start command to the following.
"start": "nodemon -L --watch 'src/**/*.ts' --exec ts-node src/main.ts",

Answer 2

You can set to ignore watch in package.json
"watch": {
"ignore": "upload"
}
