TensorFlow.js Examples

This repository contains a set of examples implemented in TensorFlow.js.

Each example directory is standalone so the directory can be copied to another project.

Dependencies

Except for getting_started, all the examples require the following dependencies to be installed.

How to build an example

cd into the directory

If you are using yarn:

cd mnist-core
yarn
yarn watch

If you are using npm:

cd mnist-core
npm install
npm run watch

Details

The convention is that each example contains two scripts:

  • yarn watch or npm run watch: starts a local development HTTP server which watches the filesystem for changes so you can edit the code (JS or HTML) and see changes when you refresh the page immediately.

  • yarn build or npm run build: generates a dist/ folder which contains the build artifacts and can be used for deployment.

Contributing

If you want to contribute an example, please reach out to us on Github issues before sending us a pull request as we are trying to keep this set of examples small and highly curated.

Running Presubmit Tests

Before you send a pull request, it is a good idea to run the presubmit tests and make sure they all pass. To do that, execute the following commands in the root directory of tfjs-examples:

yarn
yarn presubmit

The yarn presubmit command executes the unit tests and lint checks of all the exapmles that contain the yarn test and/or yarn lint scripts. You may also run the tests for individual exampls by cd'ing into their respective subdirectory and executing yarn, followed by yarn test and/or yarn lint.
