Frontend customization (prior to 2023.03)

Important

The customization steps described here are not fully up-to-date with the Docker deployment.

To create a future-proof customization, also check notes in Example: Change favicon, add custom CSS and Google Analytics.

The frontend created using Angular framework is located at these paths:

  • /var/webapps/fleio/frontend/staff - staff panel

  • /var/webapps/fleio/frontend/enduser - enduser panel

Adding new themes

Important

If you are adding or changing Fleio files, other than Fleio setting files that are stored in Docker volumes, see Adding or changing files in Fleio Docker images.

First, we’ll use a local environment to write the .scss custom theme and generate our .css file that we’ll deploy on production. Use the following procedure (adapt to your operating system if needed). We’ll use demo as the name for our custom theme.

Note

You may need to specify @angular/cli and @angular/material specific versions in the following commands, check template notes related to your Fleio version first.

apt update
apt install npm
npm install -g @angular/cli
ng new demo --style=scss  # answer no to questions
cd demo
ng add @angular/material  # when asked for prebuilt theme choose CUSTOM then answer no to the next questions

Now, edit the demo/src/styles.scss file. Remove its contents if any.

This is how our template may look:

Template for 2023.02 or newer

Important

Adapt this template if you’re using Fleio 2023.02 or newer. Themes generated using this template will not work with 2023.01.1 or older.

Requirements:

  • have node v18.13.0 installed

  • when running npm install -g @angular/cli specify version “15.1.3”, e.g.: npm install -g @angular/cli@15.1.3

  • when running ng add @angular/material specify version “15.1.2”, e.g.: ng add @angular/material@15.1.2

Notable changes from previous version:

  • $demo-theme: mat.define-light-theme() statement now takes a color parameter

  • @include mat.all-component-themes($demo-theme); statement becomes @include mat.all-legacy-component-themes($demo-theme); - this is because we’ve updated Angular & Angular Material to version 15 and we’re using legacy components until we completely migrate to the MDC-based Angular Material Components

Building the theme for 2023.02 or newer

It is enough to overwrite $demo-primary, $demo-accent, $demo-warn and $demo-primary-color variables in order to just change the primary/secondary colors. However, you can dig further and edit the styling, positioning, etc. of any element of the app.

You can also make use of some already defined color palettes (e.g.: mat.$blue-palette) from Angular Material which can be found in node_modules/@angular/material/core/theming/_palette.scss.

For additional information, you can read: Angular Material theming guide, Sass/scss basics.

Once all changes are done we need to generate the .css file:

ng build

Now locate the demo/dist/demo/styles.xxxxxxx.css file, rename it to demo.css (use your theme name instead of default name, very important) and add the theme to your installation following this guide: Adding new themes in Docker install.

After that include the theme in the available themes list by editing panels configuration files and updating the “availableThemes” setting like described here: Configure which themes show up in my profile.

...
"settings": {
    ...
    "availableThemes": ["demo"],
    ...

Notice we removed “spring” from the availableThemes default array. In this case, we’ll need to also change the app default theme using the defaultTheme property:

...
"settings": {
    ...
    "defaultTheme": "demo",
    ...

Now users will have another default theme and they can change it from their user’s profile page, if any other themes are available.

Building the theme for 2023.01 or older

It is enough to overwrite $demo-primary, $demo-accent, $demo-warn and $demo-primary-color variables in order to just change the primary/secondary colors. However, you can dig further and edit the styling, positioning, etc. of any element of the app.

You can see that for primary, accent and warn palettes we use already defined color palettes provided by Angular Material (e.g. $mat-amber, $mat-brown, $mat-red). You can find additional already defined palettes like those in node_modules/@angular/material/_theming.scss (just search for those we’ve already used in our demo) and you can make use of them just like we did above. If you wish to define your own palette you can take some inspiration from those that are already defined, add them in the styles.scss file and make use of them.

For additional information, you can read: Angular Material theming guide, Sass/scss basics.

Once all changes were done we need to generate the .css file:

ng build --prod --extract-css

Now locate the demo/dist/demo/styles.xxxxxxx.css file, rename it to demo.css (use your theme name instead of default name, very important) and copy it on your fleio installation in /var/webapps/fleio/frontend/staff/assets/themes or /var/webapps/fleio/frontend/enduser/assets/themes directory.

Once copied, you will need to add your theme in the available themes in panel’s config file. Edit /var/webapps/fleio/frontend/PANEL_NAME/assets/config/PANEL_NAME.config.json settings > availableThemes property to look like this (or add it, if missing):

...
"settings": {
    ...
    "availableThemes": ["demo"],
    ...

Notice we removed “spring” from the availableThemes default array. In this case, we’ll need to also change the app default theme using the defaultTheme property:

...
"settings": {
    ...
    "defaultTheme": "demo",
    ...

Now users will have another default theme and they can change it from their user’s profile page, if any other themes are available.

Adding new themes in Docker install

First, you need to generate the theme .css file as in the above docs.

After that, you’ll need to change the index.html file for each panel you want and to and include the customized .css file. To do so, read the following guide: Adding or changing files in Fleio Docker images.

Here are a few notes:

The css theme file should be copied like this (do so for every panel):

COPY theme_name.css "$INSTALL_PATH/frontend/staff/assets/themes/theme_name.css"
COPY theme_name.css "$INSTALL_PATH/frontend/enduser/assets/themes/theme_name.css"

Also, the sed command from the Dockerfile should look like this (do so for every panel):

RUN sed -i \
's^</head>^<link rel="stylesheet" type="text/css" \
href="assets/themes/theme_name.css" \ media="screen"/></head>^' \
"$INSTALL_PATH/frontend/staff/index.html"

RUN sed -i \
's^</head>^<link rel="stylesheet" type="text/css" \
href="assets/themes/theme_name.css" \ media="screen"/></head>^' \
"$INSTALL_PATH/frontend/enduser/index.html"

Remember to update the availableThemes setting from angular configs as described in the previous section by using the following command (do so for every panel):

fleio edit staff.config.json
fleio edit enduser.config.json

How to change the logo in Docker install
