24 tools

• 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.

• 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, versions and logs included. Only the default: whoever opens the editor can swit

• 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/: its .cs files are compiled, in any folder, as in a C# project - lambda.cs returns

• 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 saved into that feature - the way to work on a lambda that exists: change it as of

• 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 tests included) and a copy of the lambda's data, and gets an address of its own to t

• 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 branched off: bring the newer versions' changes into the feature first, then move bas

• 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's documentation and tests, so bring them up to date in the feature first, and ru

• 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.

• 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.

• 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 data, leaving the lambda alone. Returns diagnostics on failure, and whatever was o

• 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, the workspace and the secrets: whether each is on, what it holds, and which sec

• 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 and day. With feature, what that feature's preview has been doing instead, kept ap

• 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 without touching the real one. For files the lambda works with at runtime (pictu

• 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 resources of a version are in read_lambda.

• 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.

• 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 'workspace' (on unless the owner switched it off). Do it when what you build needs it -

• 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 that table's rows, newest first, up to 100 at a time. Read only: the lambda wri

• 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 be read back, by you or the owner; only the lambda reads it, from its next call

• 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 still has to set - and which it only uses when they are there, checked with Sec

• 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 copy instead.

• 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 needs a title, a description and a picture (a screenshot or short GIF of the lamb

• 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 program and what is written about it - every version's code, resources, documentatio

• 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 public and read only: read the closest one with read_lambda (and list_files, read_

• 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 snippet returns, what is imported, what is refused, limits and terms.
