To run app

From root

• run typescript project npm i --prefix examples/js_dom_draw_bechmark_chart/typescript_vanilla_typeorm npm run start:dev --prefix examples/js_dom_draw_bechmark_chart/typescript_vanilla_typeorm

• run v project v run examples/js_dom_draw_bechmark_chart/v_vweb_orm

• running v chart cd examples/js_dom_draw_bechmark_chart/chart && v run .

Dockerfile [docker build]=> Docker image [docker run]=> Docker container

sudo docker build -t <name> .

sudo docker run --name <container name> --interactive --tty --publish 3001:3001 <name>

v run .

A message like [Vweb] Running app on http://localhost:3001/ should appear

exit

To implement new benchmarks in v

In examples/js_dom_draw_bechmark_chart/v_vweb_orm/src/main.v path Create a route returning a Response struct like:

['/sqlite-memory/:count']
pub fn (mut app App) sqlite_memory(count int) vweb.Result {
	mut insert_stopwatchs := []int{}
	mut select_stopwatchs := []int{}
	mut update_stopwatchs := []int{}

	mut sw := time.new_stopwatch()

	mut db := sqlite.connect(':memory:') or { panic(err) }

	sql db {
		create table Task
	}!

	task_model := Task{
		title: 'a'
		status: 'done'
	}

	for i := 0; i < count; i++ {
		sw.start()
		sql db {
			insert task_model into Task
		} or { []Task{} }
		sw.stop()
		insert_stopwatchs << int(sw.end - sw.start)
	}

	sql db {
		drop table Task
	}!

	response := Response{
		insert:	insert_stopwatchs
		@select:select_stopwatchs
		update:	update_stopwatchs
	}
	return app.json(response)
}

In examples/chart/services.v path Create a service to request the benchmarks data by http Decode the info to FrameworkBenchmarkResponse

fn typescript_sqlite_memory() ?FrameworkBenchmarkResponse {
	url := 'http://localhost:3000/sqlite-memory/${benchmark_loop_length}'
	res := http.get(url) or { panic(err) }
	framework_benchmark_response := json.decode(FrameworkBenchmarkResponse, res.body)!
	return framework_benchmark_response
}

In examples/chart/main.v path Create a service to request the benchmarks data by http Decode the info to FrameworkBenchmarkResponse

fn typescript_sqlite_memory() ?FrameworkBenchmarkResponse {
	url := 'http://localhost:3000/sqlite-memory/${benchmark_loop_length}'
	res := http.get(url) or { panic(err) }
	framework_benchmark_response := json.decode(FrameworkBenchmarkResponse, res.body)!
	return framework_benchmark_response
}

Then, update: insert_framework_benchmark_times(); select_framework_benchmark_times(); update_framework_benchmark_times(). with the new function
