Restoring the support images: \n png2pdf: \n Without this cache you need to convert png to pdf manualy or you risk a compile timeout (had this problem yesterday and did the conversion manualy. Compile time reduction was from time out to 3sec.)\n env settings required:\n (mount point INSIDE the container)\n CLSI_CACHE_PATH: /var/lib/overleaf/data/cache \n (Mount point outside of the container i.e. host, based on your compose volume rules)\n SANDBOXED_COMPILES_HOST_DIR_CACHE: points to the same folder outside of the container\n Test parameter:\n PNG2PDF_MIN_FILE_SIZE_BYTES: 1024 \n ENABLE_PNG2PDF_CONVERSIONS: true \n PNG2PDF_IMAGE: sharelatex/png2pdf:2026-06-24 \n\n It acts on slow png conversions and not all. Hence the texlive image needs this detection hook as the creator intended it. I added them to:\n https://github.com/davrot/texlive-full/tree/png2pdf-slow \n It is a modification of the LatexMK file. Without the hook no png files are cached as pdf.\n\n pdftocairo: \n The creater intended that pdf to thumbnail / preview are created by an external container for safety reasons. \n The only action we do a to-thumbnail-conversion is in the template generation. Since we don't want to disapoint the creater, I restored this safety feature.\n env settings required:\n (default: local imagemagick; other options are local pdftocairo and container pdftocairo via pdftocairo-sandbox)\n CONVERTER: pdftocairo-sandbox \n CONVERSION_SANDBOX_IMAGE: sharelatex/pdftocairo:24.02 \n (mount point INSIDE the container)\n CONVERSION_SANDBOX_DIR: /var/lib/overleaf/tmp/conversions \n (Mount point outside of the container i.e. host, based on your compose volume rules)\n CONVERSION_SANDBOX_HOST_DIR: points to the same folder outside of the container\n

overleaf/web

overleaf/web is the front-end web service of the open-source web-based collaborative LaTeX editor, Overleaf. It serves all the HTML pages, CSS and javascript to the client. overleaf/web also contains a lot of logic around creating and editing projects, and account management.

The rest of the Overleaf stack, along with information about contributing can be found in the overleaf/overleaf repository.

Running the app

The app runs natively using yarn and Node on the local system:

$ yarn install
$ yarn run start

Running Tests

To run all tests run:

make test

To run both unit and acceptance tests for a module run:

make test_module MODULE=saas-authentication

Unit Tests

The test suites run in Docker.

Unit tests can be run in the test_unit container defined in docker-compose.tests.yml.

The makefile contains a short cut to run these:

make test_unit

During development it is often useful to only run a subset of tests, which can be configured with arguments to the mocha CLI:

make test_unit TEST_NAME_PATTERN='AuthorizationManager'

To run only the unit tests for a single module do:

make test_unit_module MODULE=saas-authentication

Module tests can also use a TEST_NAME_PATTERN argument:

make test_unit_module MODULE=saas-authentication TEST_NAME_PATTERN=SSO

Acceptance Tests

Acceptance tests are run against a live service, which runs in the acceptance_test container defined in docker-compose.tests.yml.

To run the tests out-of-the-box, the makefile defines:

make test_acceptance

However, during development it is often useful to leave the service running for rapid iteration on the acceptance tests. This can be done with:

make test_acceptance_app_start_service
make test_acceptance_app_run # Run as many times as needed during development
make test_acceptance_app_stop_service

make test_acceptance just runs these three commands in sequence and then runs make test_acceptance_modules which performs the tests for each module in the modules directory. (Note that there is not currently an equivalent to the -start / -run x n / -stop series for modules.)

During development it is often useful to only run a subset of tests, which can be configured with arguments to the mocha CLI:

make test_acceptance_run TEST_NAME_PATTERN='AuthorizationManager'

To run only the acceptance tests for a single module do:

make test_acceptance_module MODULE=saas-authentication

Module tests can also use a TEST_NAME_PATTERN argument:

make test_acceptance_module MODULE=saas-authentication TEST_NAME_PATTERN=SSO

Routes

Run bin/routes to print out all routes in the project.
