You can import the JavaScript -agent by using `import * as agent from '@dfinity/agent'` which is as -close as it can be to the real world. - -== Starting / Stopping the Replica - -The `setup` Jest step starts the replica using `dfx replica`. The `teardown` step sends -a SIGTERM to the `dfx` process. Nix will wait for all children and descendants to be -stopped, so Nix will timeout and fail if the replica isn't properly killed. - -== Adding New Tests - -Adding a test is just a matter of having a file with a `.ts` extension anywhere outside -the root directory of tests and the `utils/` folder. This is driven by the -`jest.config.js` file which has a pattern matching all those files. - -We don't force users to have a `.test.ts` extension as this whole folder is meant to be -tests. It's just simpler that way. - -== Using HttpAgent - -The `utils/` folder contain an `agent.ts` file which exports an `HttpAgent` instance -which connects to the testing Replica. Unless required by your test to have a special -agent configuration, you should always reuse that one. - -== Creating and Using Canisters - -Right now, the way to add a canister is to manually build it and check in the canisters -WASM. This is a limitation of the current setup and will (hopefully) go away soon. - -Once the WASM is checked in, a canister `.ts` should be added which exports a factory. -That factory reads the WASM, creates an actor with a random canisterId, builds the IDL -manually (currently) and install the canister on the Replica. A good example of this -can be seen in `utils/canisters/counter.ts`. - -= TODOs - -- [ ] Add a dfx project derivation which generates the WASM and IDL through Nix - so it doesn't have to be checked in. -- [ ] Also, reuse canister IDs exposed by the dfx project derivation above instead - of generating a random one.

How to Run Locally

-
-
-

Locally in your sdk repo, execute:

-
-
-
    -
  1. -

    npm install. To install all Node dependencies.

    -
    2. -
  2. -

    npm run webpack — --watch will start webpack in watch mode.

    -
    3. -
  3. -

    In two separate terminals in a DFX project (create one if needed);

    -
    -
      -
    1. -

      Start a dfx replica.

      -
      2. -
    2. -

      Start dfx bootstrap --root $SDK_REPO_PATH/src/bootstrap/dist/ --providers http://localhost:8080 --port 8000.

      -
      3. -
    -
    -
    4. -
  4. -

    Open your browser to http://localhost:8000. Change code, wait a few seconds for webpack to -build, reload browser.

    -
    5. -
-
-
-

If you need HTTPs (for example, using lvh or ic0.app using redirects), you will need to setup -your own nginx reverse proxy. Look up instructions online.

-
-
-

Note that HTTPS is needed for the crypto API if you’re accessing a non-localhost URL. This is -a limitation of the web API (see ).

Startup Process

-
-
-
    -
  1. -

    The bootstrap server determines which worker host it is using;

    -
    -
      -
    1. -

      If there is a query param workerHost, use that value.

      -
      2. -
    2. -

      If there is a dfinity-ic-host value in local storage, uses that value.

      -
      3. -
    3. -

      If the host ends with localhost and contains more than 1 subdomain, use dfinity.localhost. -This is used to test cross-domain worker.

      -
      4. -
    4. -

      If the host ends with lvh.me, use dfinity.lvh.me. This is used to test cross-domain worker.

      -
      5. -
    5. -

      If the host ends with ic0.app, use dfinity.ic0.app.

      -
      6. -
    6. -

      Otherwise, don’t use a worker (this is for localhost and development purposes).

      -
      7. -
    -
    -
    2. -
  2. -

    The bootstrap server determines the canister ID;

    -
    -
      -
    1. -

      If there is a query param for canisterId, decode that value as text.

      -
      2. -
    2. -

      If there is a dfinity-canister-id value in local storage, uses that value.

      -
      3. -
    3. -

      If the host ends with lvh.me, split the host and use the first subdomain before -ic0.app. For example, some-sub.01234567.lvh.me would result in 01234567. -This is used to test cross-domain worker.

      -
      4. -
    4. -

      If the host ends with ic0.app, split the host and use the first subdomain before -ic0.app. For example, some-sub.01234567.ic0.app would result in 01234567.

      -
      5. -
    5. -

      Otherwise, show a UI for the user to enter a canister ID.

      -
      6. -
    -
    -
    3. -
  3. -

    Create a worker with ${workerHost}/worker.js using the same protocol.

    -
    4. -
  4. -

    Get the canister’s /index.js through the worker.
