ts-benchmark

Installation:

npm i ts-benchmark -g

Description:

A command line interface for monitoring the performance of typescript.

Features:

• Ability to specify specific fields of benchmark result.
• Watcher which trigger benchmark process on any change made to the specified path.
• It can be use to benchmark two different branches.

---

Usage:

Benchmark the current directory:

ts-benchmark

Benchmark test folder which is test project and watch changes on src folder to trigger benchmark:

ts-benchmark -p ./test -w ./src

Like the previous command but it will shows specific fields of benchmark result instead of all fields:

ts-benchmark -p ./test -w ./src -f 17 18 29 32

Similar to the previous command but it will check if field 17 has reached the maximum valid value "10000":

ts-benchmark -p ./test -w ./src -f 17/10000 18 29 32

Benchmark test folder watch changes on src folder after benchmark master branch:

ts-benchmark -p ./test -w ./src -b master

Options:

option	description	type	default
-p, --path	A relative path to project that will be benchmarked.	string	./
-w, --watch	A relative path to a directory or a file that trigger benchmark process on any changes.	string	undefined
-b, --branch	Another git branch name to be benchmarked and compared with the current branch.	string	undefined
-s, --save	To save and show the previous benchmark result.	boolean	false
-i, --initial	To save and show the initial benchmark result.	boolean	false
-f, --fields	To pick and show specific fields of benchmark result by its index numbers. Maximum valid valid can be set by adding "/" and then maximum value like: 17/10000	array of index numbers between 1-32	undefined
-g, --github	To make the tool integrate with github workflow. "will throw error on failure if a field has overpassed its maximum valid value."	boolean	false
-t, --target	Useful for benchmarking targeted branch of github pull request. -g flag should also be set to true as well."	boolean	false
--help	Show help	boolean	false
--version	Show version	boolean	false
