From 17fe607ce5877b251d4eb9bb1fa394e807f4ad39 Mon Sep 17 00:00:00 2001 From: Steve Lohr Date: Tue, 26 Nov 2024 09:19:50 +0100 Subject: [PATCH] Migrate JavaScript to Golang Related to #127 Migrate the codebase from JavaScript to Go. * **Dockerfile**: Update the base image to use a Go image, install dependencies from `go.mod`, and build the Go application. * **README.md**: Update instructions to reflect the migration to Go, including dependencies and build instructions. * **app.js to app.go**: Migrate the main application setup, including database connection, session setup, and route definitions. * **controllers/impressum.js to controllers/impressum.go**: Migrate the `impressum` function to use Go's `net/http` package and templates. * **controllers/landingPage.js to controllers/landingPage.go**: Migrate the `landingPage` function to use Go's `net/http` package. * **controllers/title.js to controllers/title.go**: Migrate the `postTitle`, `getTitles`, `getTitle`, `updateTitle`, and `deleteTitle` functions to use Go's `net/http` package and `database/sql` package. * **index.js to index.go**: Migrate the server setup code to use Go's `net/http` package and TLS configuration. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/schdief/moveez/issues/127?shareId=XXXX-XXXX-XXXX-XXXX). --- services/gui/Dockerfile | 14 +- services/gui/README.md | 39 +++- services/gui/app/app.go | 105 +++++++++++ services/gui/app/app.js | 118 ------------ services/gui/app/controllers/impressum.go | 24 +++ services/gui/app/controllers/impressum.js | 9 - services/gui/app/controllers/landingPage.go | 14 ++ services/gui/app/controllers/landingPage.js | 11 -- services/gui/app/controllers/title.go | 179 ++++++++++++++++++ services/gui/app/controllers/title.js | 196 -------------------- services/gui/app/index.go | 91 +++++++++ services/gui/app/index.js | 34 ---- services/gui/app/login.go | 75 ++++++++ services/gui/app/login.js | 90 --------- services/gui/app/models/title.go | 21 +++ services/gui/app/models/title.js | 20 -- services/gui/app/session.go | 27 +++ services/gui/app/session.js | 18 -- services/ketchup/ketchup.go | 117 ++++++++++++ services/ketchup/ketchup.js | 93 ---------- 20 files changed, 699 insertions(+), 596 deletions(-) create mode 100644 services/gui/app/app.go delete mode 100644 services/gui/app/app.js create mode 100644 services/gui/app/controllers/impressum.go delete mode 100644 services/gui/app/controllers/impressum.js create mode 100644 services/gui/app/controllers/landingPage.go delete mode 100644 services/gui/app/controllers/landingPage.js create mode 100644 services/gui/app/controllers/title.go delete mode 100644 services/gui/app/controllers/title.js create mode 100644 services/gui/app/index.go delete mode 100644 services/gui/app/index.js create mode 100644 services/gui/app/login.go delete mode 100644 services/gui/app/login.js create mode 100644 services/gui/app/models/title.go delete mode 100644 services/gui/app/models/title.js create mode 100644 services/gui/app/session.go delete mode 100644 services/gui/app/session.js create mode 100644 services/ketchup/ketchup.go delete mode 100644 services/ketchup/ketchup.js diff --git a/services/gui/Dockerfile b/services/gui/Dockerfile index 9f06343..93f8d3d 100644 --- a/services/gui/Dockerfile +++ b/services/gui/Dockerfile @@ -1,4 +1,4 @@ -FROM node:alpine +FROM golang:alpine LABEL maintainer="schdief.law@gmail.com" LABEL service="moveezgui" @@ -9,15 +9,17 @@ ENV RELEASE ${RELEASE} # working directory for moveez WORKDIR /usr/src/app -# install dependencies from package.json, but no dev -COPY package*.json ./ -RUN npm install --only=prod --no-optional +# install dependencies from go.mod +COPY go.mod ./ +RUN go mod download # bundle app source -# TODO: remove unncessary files like test directory COPY . . +# build the Go application +RUN go build -o main . + EXPOSE 80 # start moveez -CMD [ "npm", "start" ] \ No newline at end of file +CMD ["./main"] \ No newline at end of file diff --git a/services/gui/README.md b/services/gui/README.md index 3a35e77..0c754f7 100644 --- a/services/gui/README.md +++ b/services/gui/README.md @@ -22,4 +22,41 @@ Access the moveez app page on https://developers.facebook.com.
