Running script when ts-node-dev restarts server - node.js

Question

I currently have ts-node-dev installed with my node js server and have it watching my .ts files with the --respawn flag. My server is getting successfully restarted, but I when a .ts file changes, I need to run a command like yarn build to compile the changed files (or all files) to make sure my changes are present in the restarted server.
I can't seem to find a way to run a script when the server restarts.
I have tried something like:
"start": "ts-node-dev --respawn --transpile-only yarn build && src/main.js"
In my package.json, but it tries to resolve my yarn build command as a file name.
How can I tie a script into my restarting process?
{
"compileOnSave": true,
"compilerOptions": {
"target": "es2017",
"lib": ["es2017", "esnext.asynciterable"],
"module": "commonjs",
"moduleResolution": "node",
"rootDir": ".",
"sourceMap": true,
"newLine": "LF",
"forceConsistentCasingInFileNames": true,
"noImplicitReturns": true,
"strict": true,
// For typeORM support
"experimentalDecorators": true,
"emitDecoratorMetadata": true,
"strictPropertyInitialization": false,
"pretty": true,
"typeRoots": ["node_modules/#types"]
},
"include": ["src/**/*", "db/**/*", "swagger/**/*", "test/**/*"]
}
This is my tsconfig.json, how do I specify with the watch command to watch all the src files and folders?

According ts-node-dev documentation the command is:
ts-node-dev --respawn --transpileOnly <YOUR TS FILE>
You should try on your start script on package.json:
"dev": "ts-node-dev --respawn --transpileOnly --watch src,db,swagger,test src/main.ts"
"start": "node dist/src/main.js"
In your tsconfig.json file, you should have the outDir config, this config defines the folder that you compiled code will be placed, for instance, look at my tsconfig.json:
{
"compilerOptions": {
"module": "commonjs",
"esModuleInterop": true,
"target": "ES2017",
"moduleResolution": "node",
"outDir": "./dist",
"strict": true,
"strictPropertyInitialization": false,
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true
},
"exclude": ["node_modules"],
"include": [
"./src/**/*.tsx",
"./src/**/*.ts",
"src/__tests__",
"./src/**/*",
]
}
I have the outDir config, when I run tsc or npm run build, a dist folder will be created, and inside there's will be all my .js files
