Tools (25)
| Name | Description | Schema |
|---|---|---|
enable_data | Switch on a kind of data the lambda needs and does not have: 'database' (a SQLite database for its records - off until switched on, which makes it, empty), 'secrets' (off until switched on) or 'worksp | typed |
create_lambda | Create a lambda. Returns its public address and a private editor key, the only way back in. It starts with version 1 - an empty starter, or a copy of a demo. Nothing is online until deploy. | typed |
update_lambda | Change how a lambda's editor opens: view 'Simple' shows the app, how it is doing and a box to ask for a change - for an owner who does not write code - and 'Full' every section, the code, files, data, | typed |
write_code | Save every file, replacing the previous set: as a new version of the lambda, or - with feature - into that feature. A version is its code and its resources. The code is every file not in resources/: i | typed |
change_code | Change some files: add or replace files, remove files, or replace text within a file. Everything not named stays as it is, so there is no need to resend unchanged files. With feature, the change is sa | typed |
create_feature | Start a feature: a place to change a lambda without touching what it has online. It branches off a version - the newest unless base names another - with a copy of its files (its documentation and test | typed |
update_feature | Rename a feature, change what it says about itself, or move its base. merge_feature refuses a feature that is not based on the newest version, since merging it would undo what was saved after it branc | typed |
list_demos | Demos this platform keeps online, each a finished lambda showing one way to build something: a REST API over records, registration and login, a websocket game, uploads, live updates. Their keys are pu | typed |
merge_feature | Make a feature's files the next version of the lambda, and delete the feature with its preview and its copy of the data - the lambda's own data is not touched. Its docs/ and tests/ become the version' | typed |
delete_feature | Throw a feature away: its files, its preview and its copy of the data. The lambda is not touched. For a feature the user does not want after all. | typed |
check_code | Compile without saving or deploying; returns diagnostics with file and line. Does not build the handler, so deploy can still refuse a route whose return type cannot be served. | typed |
deploy | Deploy (publish) a saved version so it goes live at its public address - the newest by default. With feature, deploy that feature's files to its own preview address instead, against its copy of the da | typed |
read_lambda | A lambda's status (online version, newest version, expiry, its tier and what it may use there), its open features, the recent versions with what each was asked for and changed, its data (the database, | typed |
read_logs | What a deployed lambda has been doing: its recent requests and how they were answered, what it printed, the errors it threw with their stack traces, and how much traffic it has had in the last hour an | typed |
upload_file | Write a file to the lambda's workspace - its data, which every version shares and no deploy, rollback or merge touches. With feature, to that feature's copy of the data instead, for trying things out | typed |
list_files | The lambda's data: whether its workspace is switched on, and every file in it with size and last write - the same whichever version is online. With feature, that feature's copy of it. The code and res | typed |
delete_file | Remove a file, or a folder with its contents, from the workspace - the lambda's data, shared by every version. No deploy or rollback brings it back. With feature, from that feature's copy instead. | typed |
read_database | The lambda's database - its records, shared by every version: whether it is switched on, how full it is, and its tables and views with their columns and how many rows each holds. With table, a page of | typed |
set_secret | Store an API key, password or token under a name the code reads with Secret.Read("NAME") - never put one in the code, a resource, the workspace, a log line or a note. The value is sealed and can never | typed |
list_secrets | The lambda's secrets by name - never their values: whether secrets are switched on, what is stored and when, which names the code reads with Secret.Read and have no value yet (missing) - what the user | typed |
delete_secret | Remove a secret. Code that reads it with Secret.Read fails from its next call on. Only when the user asks for it, or a secret you stored yourself is no longer used. With feature, from that feature's c | typed |
showcase | List a lambda on the public showcase page, change its entry, or take it off. Not part of building: only do this when the user asks for it. With only privateKey it returns the current entry. An entry n | typed |
open_source | Publish a lambda's source code at /source/{publicKey} for anybody to read, star and download as a .NET project, change the license it is published under, or take it down. What is published is the prog | typed |
analytics | How people reach a lambda, as its owner sees it in the editor: visitors, pages opened and requests per day, and the pages, referring sites, countries, devices, browsers, operating systems and crawlers | typed |
platform_guide | How this platform works - read it first: what a version, a feature and data are and how long each lives, what is code and what is a resource, the documentation and tests every version keeps, what the | typed |
