Code-runner server for each language

cb-code-runner

Application that reads json payload from request body, executes the code, and return json output. Clone of glot.io. Modified to combine server + code runner into one application.

Testing

To test the Go code execution program, first install dependencies with go get then start the server:

PORT=8085 go run runner.go

Then test the program by running:

curl -X POST -d "{\"language\": \"javascript\",\"files\": [{\"name\": \"main.js\",\"content\": \"console.log(2+2+2);\"}]}" http://localhost:8085

To build the Go binary, run:

bash build.sh

Examples

The input JSON payload expects two parameters: language and a files array with each object in files containing a file name and code content.

The output will be a JSON payload with the following parameters: stdout, stderr, error, and duration which is the execution time in milliseconds.

Input

{
  "language": "javascript",
  "files": [
    {
      "name": "main.js",
      "content": "console.log(2+2);"
    }
  ]
}

Output

{
  "stdout": "4\n",
  "stderr": "",
  "error": "",
  "duration": "37"
}
