1build Version Awesome License Build Status Go Report Card

1build is an automation tool used for research and development projects that arms you with the convenience to configure project-local command line aliases – and then run the commands quickly and easily. It is particularly helpful when you deal with multiple projects and switch between them all the time. It is often the fact that different projects use different build tools and have different environment requirements – and then switching from one project to another is becoming increasingly cumbersome. That is where 1build comes into play.

With 1build you can create simple and easily memorable command aliases for commonly used project commands such as build, test, run or anything else. These aliases will have a project-local scope which means that they will be accessible only within the project directory. This way you can unify all your projects to build with the same simple command disregarding of what build tool they use. It will remove the hassle of remembering all those commands improving the mental focus for the things that actually matter.



brew install gopinath-langote/one-build/one-build


  1. Download and install binary from the latest release
  2. Recommended: add 1build executable to your $PATH.



  • Create 1build.yaml configuration file by

    1build init --name <your_project_name>
  • Edit file according to project command list, Example of 1build.yaml for node project:

    project: Sample Web App
      - build: npm run build
      - test: npm run test

Running 1build for the above sample project

  • building the project
  1build build
  • fix the coding guidelines lint and run tests (executing more than one commands at once)
  1build lint test

Set new or update existing configuration

  • Set new command configuration for lint to "eslint server.js"
   1build set lint "eslint server.js"

Remove/Unset existing configuration

  • Unset command configuration for lint
   1build unset lint
  • To unset multiple commands at once
  1build unset lint test build

Using before and after commands

Consider that your project requires some environment variables to set before running any commands and you want to clean up those after running commands. It is a headache to always remember to set those environment variables. What you want is to set env variables automatically when you run the command in the project and remove those when the command is complete. Another example – a project requires Docker to be up and running or you need to clean up the database after running a test harness.

This is where before & after commands are useful. These commands are both optional –  you can use one of them, both or neither.


  1. Setting env variables and cleaning those up

    1build set before 'export VARNAME="my value"'
    1build set after "unset VARNAME"

    Configuration with before and after setup

    project: Sample Web App
    before: export VARNAME="my value"
    after: unset VARNAME
       - build: npm run build
  2. Ensure that Docker is up and running

    1build set before "./"
  3. Clean up database after some commands

    1build set after "./"
  4. Remove before and after commands

    1build unset before after

Using --quiet or -q flag

Sometimes you choose to not see all logs/output of your command and just see success or failure as the outcome. So using --quiet or -q flag to 1build command execution will result in just executing the command but not showing the entire output of it, only shows SUCCESS/FAILURE as result of command execution.

  1build lint test --quiet


  1build lint test -q

See 1build --help for command usages.
