You can run multiple command inside Procfile using sh -c command :

worker: sh -c 'firstCommand && secondCommand && etc...'

Notes : Procfile should be at the project root level.

For example :

worker: sh -c 'cd backend && yarn install && yarn build && yarn start-worker'

Or in your case (if u have Procfile at the same level as package.json) :

web: sh -c 'npm install && gulp build && npm run http-server'

You may also have been looking for && or a library like concurrently.

Regardless, and per the docs, use Procfile as nothing more than an entry point to your npm start script.

Use the npm scripts lifecycle as stated (npm-scripts).

Directly From The Documentation (heroku-build-process).

"scripts": {
    "start": "node index.js",
    "test": "mocha",
    "postinstall": "bower install && grunt build"
}

Heroku has adopted the 'there's an app for everything' mantra, but for buildpacks. Whatever you're building, there's a buildpack for it.

Okay, so I've spent a bit of time on that and came up with the answer. By default, heroku is installing all packages from the package.json file, so npm install is no longer required. Then what was left - gulp build and http-server.

For that case, I've added "postinstall" : "gulp build" to my package.json and it left me with web: http-server.

Simplifying things have actually solved the problem. Not sure how useful that information might be to you, but it's worth to share.
