zap

know is the abstraction. Half the joy to be found when working within massive codebases is successfully clearing lines.

you do database first. For session handling I use scs github.com/alexedwards/scs , for converting form encoded data to go structs I use github.com/gorilla/schema, for logging I use zap https://github.com/uber-go/zap. For managing roles in an app I use either the voter pattern https://symfony.com/doc/current/security/voters.html in simple cases or casbin github.com/casbin/casbin . For background jobs I used https://github.com/gocraft/work and https://github.com/gocelery/gocelery , for caching i just use redis https://github.com/go-redis/redis , for data validation I used https://github.com/asaskevich/govalidator or https://github.com/go-ozzo/ozzo-validation . For sending mails to customers I used https://github.com/go-gomail/gomail If i need html forms, I first describe form elements as a struct then write form helpers in jet templating to display them like that: type LoginForm struct { Login, Password string Form } func (form *LoginForm) validate(r *http.Request) error { r.ParseForm() form.Decoder().Decode(form, r.Form) form.Errors = map[string][]string{} if err := (requiredValidator{}).validate(form.Login); err != nil { form.Errors["Login"] = append(form.Errors["Login"], err.Error()) } if err := (requiredValidator{}).validate(form.Password); err != nil { form.Errors["Password"] = append(form.Errors["Password"], err.Error()) } return form.getErrors() } func (form LoginForm) LoginFormView() LoginFormView { return LoginFormView{Fields: []Field{ {Name: "Login", Label: "Email", Type: "text", Value: form.Login, Required: true, Errors: form.Errors["Login"]}, {Name: "Password", Label: "Password", Type: "password", Value: form.Password, Required: true, Errors: form.Errors["Password"]}, {Type: "submit", Value: "Submit", Required: true}, {Type: "reset", Value: "Reset", Required: true}, }, Method: "POST", Name: "LoginForm"} } Then I can just write an helper in jet to display the the form view: {* tag attributes *} {{ block attributes() }} {{range .}} {{.Key}}="{{.Value}}" {{end}} {{ end }} {* form field *} {{block field()}} <label> {{.Label}} <br/> {{if .Type == "textarea" }} {* textarea *} <textarea name="{{.Name}}" {{ yield attributes() .Attributes }} >{{.Value}}</textarea> {{ else if .Type == "select" }} {* select *} <select name="{{.Name}}" {{yield attributes() .Attributes }}> {{ range .Options }} <option value="{{.Value}}" {{ if .Selected }} selected {{ end }}>{{.Label}}</option> {{ end }} </select> {{ else }} {* basic input *} <input type="{{.Type}}" name="{{.Name}}" {{ if isset(.Value) }} value="{{.Value}}" {{ end }} {{ yield attributes() .Attributes }} {{ if .Checked == true }} checked {{end}} /> {{ end }} </label> {{end}} {* form template *} {{block form()}} <form action="{{.Action}}" name="{{.Name}}" method="{{.Method}}"> <fieldset> {{ range .Fields }} {{yield field() .}} {{end}} </fieldset> </form> {{end}} This is the exact app structure I use to deal with dependencies and filters : https://medium.com/statuscode/how-i-write-go-http-services-a...
