Local Environment

If you need to deploy a canister locally, you can follow these steps:

1. Install dfinity SDK

   on Ubuntu system (version 20.04) or Mac system, it is recommended to switch to root user and execute the following commands

   sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"
   
   # check
   dfx  --version
   

2. Create a demo project (type = rust)

   • Create a demo project

     dfx new --type=rust demo
     

   • Start dfx environment

     dfx start --clean --background
     

   • Start project

     dfx deploy 
     

3. Start the project with the compiled wasm package

   If there is only a compiled wasm package and no source code, you can use the following steps for local deployment：

   • Create a demo project

     dfx new --type=rust demo
     

   • Put the wasm package and did file in the project, the path is ./${path}/demo.wasm ./${path}/demo.did, where ${path} is the directory where it is placed

   • Find the dfx.json file in the project root directory, modify wasm and did, and keep the same path as the previous step

      "canisters": {
          "demo": {
              "type": "custom",
              "wasm": "./${path}/demo.wasm",
              "candid": "./${path}/demo.did"
          }
      }
     

   • Start dfx environment

     dfx start --clean --background
     

   • Start project

     dfx deploy 
     

4. Call a method on the console

   dfx canister call   canister_name method_name [argument] 
   

Test Environment

In order to facilitate developers to test, we also provide a test environment , and developers can directly call our test environment for interface access.
