Synapse React Client

This project helps you integrate your app with the Synapse API backend.

See the available Components

Getting started with Synapse. is a client written for the Synapse platform.

Interested in contributing to this project? See contributing.


Run the following command:

npm install synapse-react-client


See index.ts for a comprehensive list of components that can be used.

To function properly, all components must be wrapped in a SynapseContextProvider. To make authenticated requests, you must provide the user's access token as a property to the context provider, among other values. You may maintain this in state, or provide it however you like.

The context provider also maintains a shared cache (via react-query). It is recommended to place the provider at the highest possible point in your component tree, and to use the same provider across components if possible.


const myToken = "example-token" // this value may also be undefined, if a user is not signed in
const useUtcTime = true
const inExperimentalMode = false

<SynapseContextProvider synapseContext={{ accessToken: myToken, isInExperimentalMode: inExperimentalMode, utcTime: useUtcTime }} >
  <EntityFinder {...entityFinderProps} />

Setting Endpoints

Configuring endpoint destinations for repo and portal

Specifying the following in the window object will override request endpoints:

  PORTAL: '<endpoint>',
  REPO: '<endpoint>',

Note - this will apply to all calls being made.


We are primarily using MUI for styling and per-app theming. We provide a default theme in DefaultTheme.ts which can be overridden with your own theme properties.


Synapse React Client also uses Dart Sass. The core css lives in src/style and src/template_style.

For a list of variables you can override, see src/style/abstracts/_variables.scss.

Override the variables by importing the SCSS in your project like so:

@use 'synapse-react-client/dist/style/main.scss' with ($primary-action-color:
      $-my-primary-color, $secondary-action-color: $-my-secondary-color, // ...any other overrides continue);
@use 'synapse-react-client/dist/template_style/Index.scss';

In this example, make sure that your node_modules folder is in your Dart Sass load path.

Adding a new component and Publishing a new version of SRC

To expose a component from the library you must export it from index.ts. Ideally, your component will get its own subfolder within src/components/, which will contain an index.ts file that exports the public API of the component (typically the component and its props type). In src/components/index.ts, you can then export the contents of the new subfolder.

To expose a component for use in, you must export it from umd.index.ts. Note that certain dependencies are not included in the UMD bundle. See the script that builds the bundle, src/esbuild.config.mjs, for more details.

Available Scripts

Before doing anything else run:

pnpm install

In the project directory, you can run:

pnpm start

Runs Storybook, which allows you to inspect and interact with components.

pnpm test

Launches the test runner in the interactive watch mode.

pnpm test:ci

Launches the test runner in the non-interactive mode to run all tests and calculate test coverage.

Links to Resources on Testing:

pnpm build

Bundles the library for production to the build folder.

pnpm build:js

Bundles the library for production to the build folder using tsup. This command creates CJS and ESM bundles with all dependencies removed, and also outputs a single TypeScript declaration file.

Note - this script is run automatically as part of the build command.

pnpm build:esbuild

This project can be built as a umd bundle. It produces three files

  • synapse-react-client.production.min.js
  • synapse-react-client.development.js
  • synapse-react-client.production.min.styles.css.

Note - this script is run automatically as part of the build command.
