Begin CLI
Installing
Install the Begin CLI by opening your terminal and entering the following command:
- Mac, Linux:
curl -sS https://dl.begin.com/install.sh | sh
- Then follow the printed instructions to add Begin to your
$PATH
.
- Windows:
iwr https://dl.begin.com/install.ps1 -useb | iex
By default Begin installs to ~/.begin/
(Mac, Linux) / $Home\.begin\
(Windows). You can specify a custom directory to install to by using the BEGIN_INSTALL
environment variable:
- Mac, Linux:
BEGIN_INSTALL=/whatever/path/here curl -sS https://dl.begin.com/install.sh | sh
- Windows:
$env:BEGIN_INSTALL="c:\whatever\path\here"; iwr https://dl.begin.com/install.ps1 -useb | iex
Alternatively, you can install Begin with npm: npm i -g @begin/cli
.
Running locally
Be sure to set the following environment variables:
export DEPLOY=main
export BEGIN_CLI_CLIENT_ID_STAGING=<your staging ID>
export BEGIN_CLI_CLIENT_ID_PRODUCTION=<your production ID>
Usage
Note for Windows users: begin
is a reserved word in PowerShell, so in Windows Begin is b.exe
. Any documented references to running begin
should be interpreted as running b
in Windows.
- Run
begin
to see your list of available commands - Get help:
- Providing no argument (or unknown arguments) will print help; help should never be hard to get!
- Additionally, providing the argument
help
anywhere in your command will always display relevant help (like -h
or --help
flags); for example:
begin dev help
is equivalent to begin help dev
or begin dev -h
- Disable colorized output with the
--no-color
flag, or with the following env vars: BEGIN_NO_COLOR
, NO_COLOR
, or by setting TERM
to dumb
- Output is automatically de-colorized in JSON mode (
--json
)
JSON output
Setting the --json
flag sets the output mode to JSON, intended for use with modern JSON-based workflows using tools like jq
.
As such, final JSON output is always sent to stdout
, even in the event of an error. Additionally, all ANSI colorization is automatically stripped from JSON output.
JSON schema
Successful execution:
ok
(boolean): always true
message
(string): always be present, but may be empty (""
)- Other properties: individual commands may provide their own properties; for example:
begin version
will output begin
(executable path) and version
(semver string) properties)
Unsuccessful execution
ok
(boolean): always false
error
(string): message of the errorstack
(string): stack trace of the error; only present if --debug
flag is set
CLI release channels
Begin has two release channels:
latest
(default) - well-hardened production releases following semvermain
- the newest stuff (on the main
branch, hence the name), not yet released to production
To install main directly, run:
- Mac, Linux:
curl -s https://dl.begin.com/install.sh | sh -s main
- Windows:
$v="main"; iwr https://dl.begin.com/install.ps1 -useb | iex
If you already have Begin installed, to switch to main
from latest
run: begin update --use main
.
Similarly, to switch back to latest
from main
, run: begin update --use latest
.
Tidbits
Wherever possible, the Begin CLI adheres to the Command Line Interface Guidelines.
Begin is async/await
/ Promises
-based. It is currently CommonJS, with plans to eventually refactor to ESM.
Begin is written in idiomatic JavaScript with a key exception: each command's specific require()
statements are in local scope, not global. This is specifically and deliberately done to reduce the coldstart time and ensure every execution runs as fast as possible.
